Over the past year and a half, we've received countless emails and phone calls asking where our E39
Wagon Subwoofer system had gone and whether it would be coming back. Until now, the answer has been "Sorry, but we've discontinued the system."
As you all know, we're a company run by enthusiasts, and as a showing of support for our E39 wagon brothers and sisters we've
decided to produce a limited run of the subwoofer systems.
For the first time ever, BSW is going to do a 'group buy' for one of our subwoofer systems. Priced at $499, we are offering this at a very low price in order gauge whether or not the system will find it's way back into our product mix.
The minimum run is set at 10 systems, so we'll need at least 10 pre-paid orders to start production. Once the minimum has been reached, we'll begin production if the minimum quantity is reached before October 31. Orders will ship no later than the 22nd of November, just in time for a holiday installation.
Package includes stealth enclosure, subwoofer, amplifier, brackets and all
necessary wiring and instructions.
If you are interested in this package please feel free to post in this thread, or contact us directly via email or phone. All orders will need to be taken by phone as the item is not available on our website.
Questions? Ask away!
Want to add more life and energy to your music WITHOUT giving up your trunk? Add a BSW subwoofer system!
Designed as a 100% complete, easy to install BMW subwoofer upgrade kit, our t110 BMW E39 Subwoofer System provides a simple, easy way to add a subwoofer (or replace your existing subwoofer) and dramatically enhance the impact, liveliness, and energy of your audio system without having to change any other components in your BMW -- because our t110 subwoofer system is engineered specifically for your exact BMW.
The how and why of bass in your BMW
Fully 1/3rd of all recorded music is below 80Hz (this is called bass!) Almost no interior component speaker can reproduce sound below 80Hz without high levels of distortion (some CAN reach to around 60Hz, but that's really the lower limit). The cheap paper drivers BMW uses in their audio systems are no certainly no exception to this rule.
Why? High output bass production requires that a speaker physically moves a great deal of air relative to what's required for higher frequencies. This air movement is accomplished in either or both of the following two ways:
High Excursion: Excursion refers to how far a speaker can move in or out from its resting state. The smaller the speaker, the larger the amount of excursion required to produce bass output -- and vice versa. However, a small driver with high excursion is far less efficient than a larger driver with lower excursion (require TONS of power from the amplifier) and is very impractical in a car audio situation due to the space required in front of such a driver to accomodate the movement. (It's also difficult to design a very high excursion driver that remains accurate at the limits of its movement).
Large Cone Surface: As the cone surface area of a speaker increases, the more air the driver can move -- and the more efficient a driver becomes relative to a speaker with smaller cone surface area. However, the additional mass of such a driver requires more power and a more stout motor structure (the components that control the speakers) to keep the driver controlled and accurate.
Both solutions do require substantial power output from the amplifier driving them, but power can be expensive. For cost savings reasons, manufacturers will produce a larger coned driver out of lightweight material (i.e. paper) to minimize power requirements. Unfortunately, the resulting lightweight subwoofer is flimsy, and when combined with low power yields muddy, fuzzy bass at moderate volumes and distortion at high volumes. This is PRECISELY the case in BMW's premium systems equipped with a subwoofer.
And if you don't have the premium system, because your stock amp and speakers (and even high quality component speakers and an aftermarket amp) are small in size, share the same lightweight construction, and are low in power, you'll get the same fuzzy bass, just less of it.
And so, an effective, high power subwoofer solution is needed. But with the BSW t110.e39, it doesn't have to come with sacrifices.
