    Our industry has faced a lot of downturn over the last couple years. OEM products like the Ford Sync are squeezing tight revenues in the aftermarket. In the last year, industry professionals from all over the world have been trying to work together to raise awareness of the products, and the qualified technicians who installed them. Car audio used to be a plentiful business where a talented installer like myself could make a few thousand a week, but that well is running dry. We see products like this as another thing to take food from our families, so that is why we get so passionate about it. This product fills a need, as I said, but today few people know what they need. That's why we are trying to educate the lay person, so they can make a more informed decision about what is right for them.

    I linked this thread to one of the top 12V forums and the "box" got laughed at quite a bit.

    JoeyK, Pepsi870, gmannino, and John have already said, these boxes are great for someone with no money to spend. Is this the typical BMW owner? I don't think so. Instead of pitching this cheap, quick and easy box on a BMW forum, encourage custom boxes that are going to last longer, sound better, and look better inside of a BMW owner's trunk.

    Look in the trunk of a $30000 BMW and see a $30 sub enclosure. What does that say about the owner? Broke? Uninformed? Fell for the hype?

    As a BMW owner AND a professional installer for 11 years, I would never install this kind of rubbish in my car or a customer's car. Period.
    Well, when we have people who claim to be 'industry experts' with 1 post, then yes, I'd say they are newbies here. Which 12V forum did you post this one, 12voltinsider? I can link this, and 99% of the installs on this site, to a forum where they'll get laughed at and ripped apart all day long, is that supposed to make me as cool as you? More money does NOT equal better.

    For the final time. The enclosure is well designed. IF glue is used, I see no difference between this, and any other enclosure, so long as it fits your requirements. Can you build a better enclosure for $30? Somehow, I doubt it. I know I can't, even if you spread out the cost of say, a sheet of MDF, screws, glue, etc.

    You're just like every other clueless car audio salesman. Go back under your rock, ok?? Car audio has seen a downturn for years, but I don't believe it has anything to do with a $30 enclosure. ALOT of it has to do with the fact that a majority of car audio install shops are VERY dishonest. Drivers have become overpriced, which has allowed the flourishment of MANY internet brands that build a quality product. Brick and mortor shops killed themselves. I'm not willing to pay $500 for a rectangular ported enclosure, are you? Or $250+ for a 'custom' sealed enclosure. Thats what ALL the shops in Upstate NY where I'm from charged, and it has helped lead to their demise. I'm sorry, but I have no sympathy for install shops that can't compete (unless, of course, all you have is BB/CC, who have killed the lower end of the market by providing massive amounts of cheap trashy equipment to the droves who will continue to purchase it).

    Also, equipment quality as a whjole has seen a massive downturn as well. Most of the big players simply don't make equipment that is anywhere near the quality of that which they did 5+ years ago. I have a pair of Orion XTR series 2 10's in my closet that I'll never sell. They're 10+ years old, and still sound great. I've had much newer XTR's, after the DEI purchase, and they simply aren't the same, and they definitely did not last. Same goes for the abundance of cheap amps. Hifonics is a great example. Hifonics used to make amazing amplifiers. Now, they don't, the failure rate that we've seen on them over the years online has been massive. US Amps sold out and is now asian made trash.

    kendogg... If you are a fan of Orion from the glory days, you have certainly heard the term "smokin' O's"? It was a reference to their amplifiers. While there is an influx of cheaper, less reliable brands, there are still some great companies producing products that excede the performance and reliablity of the days of old.

    It is true that the 12v industry has some challenges ahead. Times have changed, and many shops are struggling to keep up. There are many other shops however that are thriving. Shops that have found a way to excell even in tough economic times. One of those shops is Boulevard Customs. The shop that pepsi870 works at. It is one of the premier shops in Florida. Pepsi870 is a very skilled and talented installer. They are a shop that can "compete". They have secured a spot in their market.

    There are still great shops that offer great values to customers. There are still great manufacturers that offer great products to the consumer.

    I definitely remember that. I also remember it being a case of poor build quality the last couple years at Orion's buildhouse before they got scooped up by DEI (or so I've been told/read at least).

    Huh, strange. I've been doing this for a long time. Not sure why I've never heard of them. What subs has this company designed?

    John did most of the original design on the Eclipse Ti (9100 series) motor, as well as a few other home theater drivers, and I'm sure car drivers that I don't know about. John worked fairly closely with Thilo of TC Sounds back in the day, before Thilo screwed him, and most of the rest of his customers, before going under. Now John builds all of his drivers in-house. Also, formerly known as Stryke Audio, but was asked by RF to change the name due to infringement with Lightning Audio's apparent ownership (I think??) of that name.

    EDIT: FWIW - this is what I hate about 'people who have done this a long time'. No offense intended towards you, but shop people are always far too quick to bash brands they've never heard of. But, I'm sure the same happened of JL, RF, etc., before they were known brands......maybe??

Taking a small sealed box (these boxes do seem like small sealed boxes, even though the volume is not shown. You can calculate the internal volume by using the given dimensions) and cutting a hole and installing a port would not only hinder the performance of the sub woofer, it can easily damage the woofer and cause the voice coil to short out, which can also damage the amplifier.
    Gosh... where do I start with this.

    He didn't say 'simply cut a port and be done'. If you really took it that way, you're being WAY too literal.
    Let's take the 12" version as an example. 1.55 cubic feet is NOT a small sealed enclosure! In fact, there are probably several woofers (ones with a low Q/low VaS) that would work great in a 1.55 cu. ft. ported enclosure (provided the math was done ahead of time so that expectations were realistic). Would it be ideal? Nope. Did Tom say it would? Nope. The seller is offering a product that targets a certain market and I don't see that you have any basis for thread dumping. If you don't like it, move along. Nobody bugged you while you were attempting to pedal your services. Attacking his business makes you look like an ass. What happened to the companies you supposedly owned?

    Secondly, please state the "Scientific fact that GENERALLY says [your words, not mine]" that an improperly sized ported enclosure will cause a voice coil to 'short out'. Considering that you thought the enclosure was too small, your statement makes no sense. If the enclosure was ported and undersized, it would most likely increase the power handling, increase system Q, boominess, etc. You're more likely to damage a subwoofer from a vented enclosure that's too large due to decreased power handling but that's just my opinion and it doesn't really apply here since you thought it was too small to begin with. A vented enclosure being too large would most likely cause mechanical damage due to over-excursion, decreased power handling, increase heat in the motor assembly, etc. The voice coil may 'open' but I haven't seen many 'short out' and cause amplifier damage. I could be wrong. I'd be interested in seeing your emperical evidence on this one. State some facts and we'll all learn something.

    This enclosure could be tuned to the mid to high 30's (something the factory system can't touch) but that's really irrelavent. You're just hunting for something to pick on. He's selling a sealed, entry level enclosure for folks that want it. It's all about expectations. Nobody will argue that a properly designed and built custom enclosure will be better but that comes with a price. Tom makes no statement to the contrary. If you insist on bitching about entry level products, maybe you can bitch to the Maxxsonics guy about their shitty stuff as well. After all, they are the kings at taking good stuff and making it cheap.

    The other way an improperly ported enclosure is thought to cause damage to a woofer is related to the tuning frequency. The ratio of the surface area and length of the port along with the box volume equate to a specific frequency. Playing the subwoofer at high levels below the tuned frequency will prevent the woofers' and amplifier's ability to control the suspension of the voice coil, which causes audible popping and eventual physical damage to the coil from striking the magnet. Some woofers prevent this by not mechanically allowing the coil to strike the magnet, but most do not.

    Other than your unwarranted unneeded personal remarks about myself, there is not much to argue there. While a handful of manufacturers have made great strides in the evolution of sound quality and performance, they are often overlooked because of high marketing budgets from companies who build flashy, high profit garbage. Consumers are as much to blame, as all of us demand that products cost less and less, while innovation and raw materials continue to increase prices.

    This leads to struggling business owners becoming dishonest in the pursuit of a buck. The prices you talk about for encloses could easily be a ripoff. When I build a custom, color-matched MDF box for a single woofer, the price often hovers around $70. Its fair for my time and a fair increase over a universal over the counter design. Over time the crap shops get weeded out, like any other business, but until they do many are unknowingly taken advantage of.

    Industry leaders from all the major players recently held a summit in an attempt to raise awareness for the industry. Surveys report that less than 6% of americans can name a car audio manufacturer. We also participated in this summit and have pledged to help the effort to educate and inform the general public of whats out there so they can make an informed decision.

    The factory speakers in your car might sound good to you, until you hear a set of JL Audio's ZR line of speakers. Those are an amazing improvement in quality and performance, but then go from those and hear a properly tuned set of Hertz Mille components, and you'll be blown away how much better those can sound even over the JL. But how many of you know that they are out there?

    The more you know the better your decisions in anything in life. If you already know it all, then its time for you to move on to something else. I don't know it all, or claim to, but I have studied this art and science of audio for 10 years as a professional, so I am qualified to offer an opinion. And I offer my opinions and advice like a grown-up, without talking ill of other people who may just want to learn something.

    Thank you for your response, its pretty obvious in this thread who have professional experience and those who do not. You cannot fit a high output woofer, with is large magnet displacement and fit a port, with its displacement into these 1.55 cu ft boxes. It will be too small.

    Seriously dude, you are trying to sell us a Blaupunkt box, with foam tape sealant. This sales thread is miseducating the BMW owners of this forum.

    I really want to know, all of these guys supporting the box and talking sh*t to the rest of us opposing the box, would you really use this box in your own car?

    Go sell these boxes on another forum, not a premium line of cars like BMW.

    Depends. I recently was given permission to use a friends woodshop to build an enclosure. So, now - no. If I needed an enclosure,a nd had no place to build one myself, and this fit my needs - absolutely, without a doubt. I'd buy this over probably any other pre-fab box on the market (especially since Q Logic enclosures are WAY overpriced, and I see alot of those come apart from poor manufacturing. And the R/T boxes sold at most retailers are particle board).

    GTFO with your negativity and mindless bashing of something that you cannot compete with.

    This was part of my point before, if you 'professionals' would worry more about what YOU were doing for YOUR customers, and if you worried more about building/selling a BETTER product than you do about bashing other things that you deem 'inferior', maybe you could make the audio world a better place, instead of making DIY people like me tell you to go f*(& yourself. I'd never, EVER shop in your store if you have this attitude in person. You're that a**hole that would look at my amps you've never heard of and tell me they are junk, aren't you??

    Guys, move on please. If you don't want to use this box then DON'T. You have stated that you don't like the adhesive used on this box and I have said that you can glue it if you like. You said that this size is not for all woofers and I agree. You have said that IMPROPER port tuning is bad and I agree. (although this is not a ported box)

    This box is not for everyone, but I think most of you have agreed that it is a good inexpensive solution for someone whose speaker will work within the enclosure volumes.

    Your commments about not wanting to use it in your BMW because it is not "worthy" makes me laugh. I have seen many poorly constructed enclosures in BMW's and even more expensive cars. There is nothing wrong with the construction of this box. PERIOD.

    Please go back and cite where any of the pros on here told any DIY consumer to f themselves. All we are doing is to try and raise awareness about a certain product.

    You don't even have your own woodshop for Pete's sake! How many sub enclosures have you actually built in your lifetime? Do you know what works and what doesn't work? Do you not realize that you can't freakin assemble a sub enclosure with double sided tape?

    Do you realize that it is ghetto as he11 to take a sealed enclosure and turn it into a sealed enclosure? Besides, what is the chance that the darned sub that you already own is going to work properly with this new "ported" enclosure that you purchased. Or let me get this, you're gonna purchase the box first, and then go look for a sub that would work in it.

    Can you imagine a guy with an E39 M5 and one of those boxes in the trunk? I would laugh, and applaud the salesman that pulled one over on him.

    My god people, this is a BMW forum and not Honda Civic forum. Take pride in the products that you purchase and install in your vehicles!

    You don't even have your own woodshop for Pete's sake! How many sub enclosures have you actually built in your lifetime? Do you know what works and what doesn't work? Do you not realize that you can't freakin assemble a sub enclosure with double sided tape?

    Do you realize that it is ghetto as he11 to take a sealed enclosure and turn it into a sealed enclosure? Besides, what is the chance that the darned sub that you already own is going to work properly with this new "ported" enclosure that you purchased. Or let me get this, you're gonna purchase the box first, and then go look for a sub that would work in it.

    Can you imagine a guy with an E39 M5 and one of those boxes in the trunk? I would laugh, and applaud the salesman that pulled one over on him.

    My god people, this is a BMW forum and not Honda Civic forum. Take pride in the products that you purchase and install in your vehicles!
    Wow, I just ralized you're in L'ville, thats teh funneh. And your reading comprehension skillz are teh suck. Why don't you go ahead and re-read what you quoted, because you read it wrong.

    I've built 6 enclosures by myself in my life, and have 3 I need to build shortly. I forgot, quantity = knowledge. Thats like the people in the FI section telling me that since I don't own a turbo car, I don't know anything about turbo cars, or what they're doing wrong . Sorry, I live in a townhouse, I don't have room for a woodshop.

    You also seem to have missed the part where I AGREED that the enclosure should be glued together. If it is infact glued together, everything else about it seems to be solid construction.

    How many people do you really think buy a subwoofer then have a custom enclosure built for it? Do you have any earthly idea how many pre-fab'd enclosures are sold in this country? Any idea what woofers will/will not work in those enclosures either? Why not petition the manufacturers/salesman of those enclosures to educate their consumers on the relationship between a subwoofer and it's enclosure, rather than dog this one, which seems to be fairly well built?

    You also seem to have missed my dig on brick and mortar shops. I refuse to buy anything from a shop anymore. I may not have the install experience that a pro installer has, but 9 times out of 10 I have more knowledge of car audio and how things actually work than the ones I've met over the years. I hate being lied to by idiot salespeople. I hate having salesman/installers tell me my equipment is junk just because they've never heard of the brand (which is EXACTLY what you did in a previous post of yours). The 'pro's' that you are defending have a TERRIBLE image in the marketplace, and have a nice chunk of the downfall of this industry on their shoulders. There are thousands of posts all over the internet 'this guy sold me this, this guy tried to tel me this, I got charged this for install, was I ripped of'? and unfortunately, alot of the times, that answer is yes. Get off your high horse and accept the fact that your industry has destroyed ITSELF.

    And as far as taking pride in your BMW's - you'll have to fight that battle all over this forum. Rides n Stylin section trying to rice out their cars as much as humanly possible, people trying to turbo for as cheaply as humanly possible, etc. etc. etc.

    You crack me with this line man. 9 BOXES!!!! Wow, that's insane. I think that I built 9 boxes by the time I was 17 years old.

    According to what you just said, you have about the same hands-on experience as an average Best Buy installer.

    I've always been told that the more work that you do, the more knowledge you gain. But I guess this is not true after all.

    Anyway, keep up the good work. Hope you enjoy your prefabs, and don't quit your day job, "Dogg."

    Seriously dude, you are trying to sell us a Blaupunkt box, with foam tape sealant. This sales thread is miseducating the BMW owners of this forum.

    I really want to know, all of these guys supporting the box and talking sh*t to the rest of us opposing the box, would you really use this box in your own car?

    Go sell these boxes on another forum, not a premium line of cars like BMW.
    Slow down Greg, you're the only one talking about 'high performance woofers and megawatt power in these boxes'. And, you're only doing so in an attempt to say that this box isn't for everyone and every situation. No shit... I think we all know that - even the people that are new to this hobby. You're way off base and not even relative to the argument. I'm not defending anything but the seller's right to sell an entry level piece and marketing it as such. It's a 3/4" MDF 1.55 cu ft. box. If those dimensions work for someone, so be it. He's an authorized/paying vendor on the forum you suck up bandwidth from. And you have the nerve to tell him to go somewhere else? What a tool. Just walk away like the 28yr old man you claim to be.

    So you're telling me that everyone on this forum knows this box is not for every woofer? I did not know this knowledge was so common. Its strange but thousands of customers of mine have asked about the correct enclosure for their subs. How come those people did not know but every where knows?

    I dont think so. There are probably hundreds of people on this forum who do not have that knowledge so please leave it to people with professional experience to guide them into the correct box. You say everyone knows the box is not for every woofer, cmon, not everyone knows that. You should apologize for saying that.

    And I would have left this thread already but douche bags like you keep doing nothing but talking shit and addressing me back into the thread. You have not even contributed any technical advise to this thread. Every response from you is just negative and does not contain valuable knowledge for new comers to gain from. How many boxes have you designed and built? How many sub systems have you installed? Are you a industry professional? How many years have you been in the industry?

    So perhaps you can walk away and leave this conversation for people with experience and industry professionals so that new comers to box design and read and learn about the pro's and cons of a box like this. Again, this box is great for entry level sub systems and im sure there are lots of people who would benefit from a box like this.

    I apologize to the vendor for saying he should leave, although I dont remember saying he should leave entirely. I remember saying he should sell this box elsewhere but its too late for that.

    ^^^^ Maybe you should consider my words when I say that most industry 'professionals' aren't very trustworthy, or even professional (cough cough, YOU cough). The more you say that, the more I want to ignore you, but it's soooo hard to ignore somebody that repeatedly talks downt o people.

    Ignore me then, I dont care. I've already helped tons of people who PM with their technical questions. I'm willing to help anyone who asks me for help. I'm not trying to sell anything to rip anyone off, I have no reason to lie.

    Yes. The old 12W6's liked a good sized box, and 1.5 is about right.

    That sub would probably be OK in that box. The 12v6v2 likes 1.25 cu ft. You could always try it out as is and then add blocking inside the box (2x4s, etc.) to decrease the internal volume if you wanted to. It can be tweaked down in size that way. it's better to buy a box that slightly too big than slightly too small.

    Right, thats the v2. The originals liked a larger enclosure, just like the W0's did.

    N/A
    IIRC 1.25 was the rec sealed enclosure for the original 12w6. Keep in mind too, that the JL speces are NET, not including speaker displacement. The little extra airspace you would have with the Blau box wouldn't really be an issue, it might play a little lower due to the little bit of increased efficiency, just be aware that the power handling would be down just a little as well.. And, generally speaking, you would loose a little peakiness (from what I have seen with volume increases in sealed enclosures..).

    If you are going to buy one of those enclosures for the 12W6, I would plan on gluing and siliconing the box.

    If you can swing a custom ported box, the old JL's were awesome in a little larger vented enclosures..
