Hi Micah,

I was wondering if the amp is part of the box or separate and if it has a bass knob. Also, what's the frequency response of the sub you're using? Thanks.

Amplifier will be separate. (But this enclosure can only be purchased WITH amplifier and sub as a complete package). In most vehicles it can be mounted in the same panel on the opposite side of the trunk on an included mount. For select vehicles equipped with nav AND cd changer, you'll have to give up your CD changer for an iPod integration kit or similar if you want the amp hidden or you can mount it on the outside of the panel. Amp is very small, though, so trunk space is not impacted in any measurable way if external mounting is required.

It doesn't have a bass knob, but bass is very well blended and needs little adjustment from one recording or source to another.

Fs = 35Hz -- and the woofer plays accurately well below that. Here's a link to the specifications of the woofer we're using so you can see a frequency response curve:

Note that the prototype we built used an off the shelf woofer. Final version will likely have a subwoofer optimized specifically for this enclosure (although I'm not sure how it could sound any damn better! :))

I think I may have the distinction of having been the first to order this! Johnny, tell him what he has won!

Oops, need to do a revision of content. It is an 8."

EDIT: Fixed!

Thanks for the order, John! :)

As i mentioned in another post, my X5 was fitted with this setup by BSW and all i can say is that i am very pleased with the sound and setup. I wasn't sure what to expect when i dropped off my car, but i was amazingly surprised with the sound and solid bass levels, stealth installation, and amp setup when i picked it up. The 8" sub unit fit neatly into the compartment with the X5 specific custom-built enclosure.

Its been two weeks since i've had the unit and have had no rattling or unexpected vibrations while driving. Unfortunately I dont have DSP, but can make some slight adjustments to the bass and treble when needed and that works just fine. I'm no audio expert but the sound is incredible compared to my stock unit with no sub.

When i came to pick up the X5, Jason of BSW played a cd of The Crystal Method's Vegas and I was blown away with the bass levels in the tracks. Both Jason and Micah of Bavarian Soundwerks have been great to work with and I highly recommend this system and for the price it can' be beat.

Let me know if you have any question and i would be happy to answer them.

The way the wiring is done, is the sub input signal independent of the headunit's bass level control? Obviously some way to cross-over the lower frequencies to just the sub would free up the existing speakers to better reproduce the mid frequencies. Usually this means the sub signal must be "preamp", but BMW audio is known to be a bit quirky...so how did you guys get it to work in this particular case?

Also, how long is this sale expected to last?

You can pull the signal off of the "woofer" speakers and adjust your crossover for the sub using the aftermarket amp that's driving the sub.

Micah, is the sub designed to play through the panel covering (just like the OEM DSP system) without requiring a grill or any other opening? Hmmm...I'm still trying to figured out a way to hide my tiny amp if I decide to go this route since I DON'T want to lose my MP3 CD changer; plus the fact that I am ANTI-iPOD...can't you tell from my avatar? :D
