Musicar Level Three w/DSP

Just posting some pics of a Musicar Level Three install with DSP in a 2011 E90 M3:



We removed the stock HiFi system:



We damped the door a bit (we really don't think BMWs need much of this stuff, and we've seen some DIY jobs where people went nuts and wasted a lot of material and added weight with no real benefit):



We did a Level Three, we upgraded the woofers underseat to a new model which requires some work underseat, and we used the 2013 Helix DSP:



This was doing 24dB crossover filtering, time-domain compensation for differeing speaker lengths, channel-by-channel output level matching, and finally, 30-band parametric equalization (by 6 channels!) We're believers that compensation for the differing speaker distances is a bigger benefit than the equalization, especially with good speakers.



There is a JL 6-channel amp in the stock amp location. There is a modified Technic harness (remember there's a DSP):



Morel mids in the door, 28mm tweeters in the dash:





This is a Morel mid - not in this car, but I somehow lost the pic of this car so this is another E90 for illustration purposes (the speaker is a Morel 2012 model):



The badges were for photos for Morel's Facebook page:



The Musicar tuning cart gets rolled out:





Compare the graphs - you can see the difference between the electrical signal getting to the speaker and the acoustic signal getting to our ears:



Finally, here's the trunk after a 6-channel DSP sound system was installed:



Sounded GREAT, very musical, excellent imaging, we used the DSP to tame the stock rears a bit and make them less annoying. We hope the client will let us borrow his car for the BMW CCA meet this summer in Portland.

But what about the woofers? So, normally. Musicar systems are 100% plug-and-play, bolt-in. However, these new Level Three woofers are just too big to drop in.



Tom decided to make the stock enclosure into a mount similar to what BMW does in the E60 and E70. He made a template and used a router to mod the bottom of the enclosure, as shown:





Then we install sealing foam before bolting the speaker in:



The speaker also does require a partial ring on top to hold the carpet out of the way:



Now the speaker fits fine, and the stock speaker can still be reinstalled later.



Stock grille goes over it no problem!

So we can do this if you send in your enclosures to us for modification. We may start a core program if there is sufficient interest. The kit will include these parts but will be assembled:




This is not required for all cars - The E60 and E83 are two we know this isn't needed in, and we doubt this fits in the E70 at all (tbd). This approach is for the E90. We will be testing an E92 soon to see if this can be performed in that car.

Hah! Customer just picked it up, and he agreed - we outperformed his Burmester system in his 911! (Our instructions were to have a similar level of performance).

Drool...

Exceptional work as usual.

Just how spendy are those Maestros?

Supposedly, the play down to 30hz under the seat (per their website)! Dang!

Ummm... wow. My father had you do a parking distance retro on his new Mercedes E wagon and couldn't stop talking you guys up. This is just awesome. By chance is the integration for an enhanced-audio car as clean? Any possibility of my coming by to see what sort of options exist?
