Project: upgrading my front sound stage ('06 Vert)

Hey guys. Been wanting to replace my front stage for a while now. Have had the DLS Reference Series RM6.2 box sitting in my closet for a few (MANY) months, just waiting for a free weekend. Ta-da...free weekend. Actually I'm going to a wedding in ATL in a week, and that's perfect break-in time; DLS recommends 15-20 hours. By the end of that trip, they'll be perfectly broken!

Just a comp between the CDT mid-woofers and the DLS ones:

The DLS are MUCH beefier, heavier, deeper, and more than twice as heavy (CDT @1.69 lbs, DLS @ 3.70 lbs). Hope they don't affect my 1/4 mile times...

With the vert, you can't really block off the door panel and mount to the door like you are able to in the coupes/sedans(?).
Almost the whole door is open to the door card (thats the plastic and leather panel), making it impossible to accomplish that. So we are left with the second best option of solidifying the door-to-speaker relationship. Since it still does not provide solidity, I say don't kill yourself trying; get a good solid seal and throw some vibration damper on the door card, grab a beer and move on to other things.

Other things in my case is the fact that I want to move my tweeters from behind the metal "grills" to a more desirable spot out in front. That is going to involve destroying some things, but I will make it look good in the end. If not, I can always buy new inserts and put them in the back of the metal grills again. New inserts are cheap-cheap.

More as I have something to show...(mid, and tweeter installs and new wiring run still to come)

From my buddy. He is a dealer.

A while back, I put his "E46Fanatics Special Prices" price list in a post. You can find it if you search under my posts. His prices are awesome and for us he pays the shipping, too. Just have to mention my username.

Okay...

I got the tweeters done. I am very pleased with the way they look.

I dunno how i feel about the carbon fiber. but I do like the fact you're surface mounting them.

The mid-woofers on the other hand, have been a real bitch! I did not take into account the diameter of the magnet on the DLS. Besides that, it's just sooooo much deeper than the CDT driver. I guess the data I was using was wrong. Oh well, I WILL make it work.

I did a LOT of cutting, solder-gun plastic melting/manipulation, etc. to get that driver right up at the front of the door card. That makes more space behind it...making enough room for the driver to fit when I put the door card back on the door. (The vert has a window guide track that runs right behind the speaker magnet, so I can't cut on the door any more than I already have, during the last installation.

Right now it's held in place with 100% (black) Silicone. I will clamp it in place tomorrow; I'll have to fabricate some hold downs...I'm thinking I'll start with some metal corner brackets. Probably pound them out to about 60 (vs. 90) degrees and use the existing mounting hardware to apply the pressure. I don't know, haven't got that far yet!

Speaking of original mounting hardware, one of the screw "receptacles" broke, so I epoxy-puttied a screw in its place. I liked that better than anything else I could think of at the time. I put a nut on the top of the putty, too; now the screw can't spin in the epoxy, because the nut will make it stop.

I'll get a pic or two posted of those.

--Kinda hard to see what's going on here, but the speaker is full-on buried into that door card! I'm sure you'll be able to see the shiny aluminum cone and DLS logo even through those horrible OEM grills! Kinda excited...
(I went through hell to get to this point, which explains why this is sooooo messy and sloppy looking. Haven't done any clean-up yet.)

(I'm quite frustrated with the BMW / Harmon engineers. To put a midrange and tweeter behind a tight METAL mesh is blasphemous. And the mid-woofer grill is almost completely DIRECTIONAL. I blew across the grill at an extreme angle (like you'd blow across a coke bottle) and the air actually turned and came out straight down! That means you are getting zero off-axis sound. Weird engineering, to say the least.)

As you see, the grill was removed, and the cloth taken off and discarded. Then the placement of the tweet was determined based on keeping it within the grill.
Taped, marked, dremeled. Sounds a lot easier and quicker than it was.

Btw, anyone thinking of doing this needs to know that the area that had the HK plate is recessed. You'll have to use a hammer and something else that's flat to pound that back into a flat area; I used the wrong (flat) side of a masonry chisel. Also, it leaves two holes, so you have to re-cover it versus leaving just the metal and painting it, etc.

Finally got the mid-woofers in close enough to the back side of the grill, in order to allow the door panel to be re-installed. Man, this was tight! I had to cut, Drexel, and melt away a lot of plastic, but it fits awesome now.

Keep in mind that I am not one who cares much for good, clean installs in the places where no one else will ever see. The back of this door is a completeness, and it's ugly. I don't care, because it doesn't matter to me.

Here is the speaker buried balls-deep in that door panel (siliconed between grill and front of speaker frame):

Since it fit, I went ahead and secured it. I put thick plastic carpet protector pads on the back side of the frame. Then I was able to use fender washers on two sides; they hold it down with good pressure. For the remaining, previously damaged side, I bent and cut an angle bracket to apply the downward force that it needed.

Then I loaded up every available tree space around it with black silicone. Great for keeping that speaker in place, shock-absorbtion, de-coupling...great for sound deadening. Win-win.

how much of a difference have you noticed in bass response?

Haven't put the doors back on yet. Just got the passenger side door done yesterday, and I'm waiting for the silicone to completely out-gas before I re-install them. The doors were similar to this before with the CDT drivers, but they weren't as beefy so I didn't have these space issues.

Yesterday's work (pass side door):

Thanks! If you subscribe to this thread, I'll write a review once they are broken in.

DLS says 15-20 hours at moderate volume only, so with my upcoming road trip to ATL and back (10 hours round trip) and then a week of commuting to work and back (1.5/day), I should be able to do a recalibration on the MS-8 around the 15th or so. Then I'll post up my impressions.

By looking at this driver, I think I'm going to be very pleased!

DONE!! (for now, anyway)

I finished up last night. Everything fit nicely, and the system sounds pretty amazing. Counting down 20 hours so I can crank it up and really give it a good tweaking.
