New 3D Rotary tweeters for non-3D W222
Anyone looking to purchase: the installation was quick and easy. I've created a new thread with the door panel installation removal video in case anyone is looking. Installation was also easy (the video is playing a 2x speed).

thanks for your report i am thinking of doing the same with my car. The way you have put this report together i think i can give this a go.Thanks for your help and the time you have put into this report. cheers


All current MB sedans suffer from FrontBass syndrome. Typically, MB would use a conventional speaker array, with 6" woofers in the doors, a 4" mid and 1" silk dome tweeter, and a dedicated subwoofer on the rear parcel shelf. This is a tried and true formula that is very easy to tune.
With the introduction of FrontBass, there is neither a true sub-woofer nor any true 6" midbass speakers. Instead, MB relies on the resonating cavity in the cabin footwells to handle the whole range. Theoretically, mounting the speakers directly to the structure would give a transducer effect (the "hit" on a low frequency sound) that you can feel. That handles the ultra low end, and the resonating cavity should fill out the midbass.
In reality, um, no. The bass gets way too loose trying to play up high enough to meet the low end of the 4" midrange, and it's cutting through a lot of carpet and insulation, which makes it muddy.
With respect to the "Burmester" branding, that's exactly what it is and that's pretty much all there is. Burmester doesn't make car audio gear, and they didn't start making it when Mercedes licensed their name. The "Burmester" speakers are the same off the shelf stuff that has been installed in every Mercedes and BMW Harman/Kardon system since forever ago. I'm not saying the "Burmester" speakers are similar to the HKs...they're identical. Either they're made by Harman, or whichever supplier makes speakers for Harman also makes these.
I've auditioned the base audio in the W222 and I thought it actually sounded pretty decent. I'm not sure I'd change much. But the Burmester 3D, in addition to some more amplification, puts some real good old fashioned 6" woofers in the doors (as well as more surround speakers. But those 6" make a huge impact. For that reason alone I'd pay the freight for the 3D.
With respect to the special 3D tweeters. Starting with the optional Bang & Olfsen system in the W221, Mercedes decided to add some eye candy to distinguish the $6400 upgrade. Their solution was to pull a little razzle dazzle with the tweeters, since they're right at eye level I guess. So the B&O got very exotic looking tweeters that were also illuminated. Snazzy!
To create these exotic looking tweeters they took a plain old standard issue 1" silk dome tweeter (I have a coffee can in the garage full of them) but rather than surface mounting it vertically, like all car tweets since the dawn of time, they created a housing where the tweeter fired straight up. Obviously orienting the tweeter, which is a very directional speaker, so it fires up into the roof is a bad idea. So they created a little diffuser (they call it an "Acoustic Lense") that then reflected the tweeter's output horizontally into the cabin, which is where it belonged in the first place. All sizzle, no steak.
Likewise, to create some obvious outward expression of how much more the Burmester 3D system cost, you got the latest incarnation of the all form/no function, rotating and illuminating tweeters. I have not dissected a Burmester 3D tweeter housing but my guess is inside all that stuff is a plain old basic car audio tweeter. The rest is eye candy. Obviously, illumination is irrelevant. Rotating the speaker baffle inward toward the cabin by a half inch is likewise, um, not necessary from an audio performance standpoint.
The reason the knock-off Chinese units don't sound any worse than the standard Burmester is that in all likelihood they use the same actual tweeters.
As best I can tell, Burmester's contribution in these cars is limited to design and tuning, and in licensing their exotic premium brand name. Again, I haven't dissected a 222 so I can't say for certain. But if MB holds true to form, the Burmester in the C, E and S share components, with the S getting more stuff, although not necessarily better stuff, unless you spring for the 3D, in which you definitely get more stuff and possibly better stuff, but I doubt it.

the frontbass syndrome is annoying and the lack of equalizer tuning is annoying.. it's weird that my 87 grand national has a better equalizer in the stock radio..lol
As the 222 sits now, I'd run the Prima for 3 Way active in the front (Frontbass, 4" mid, tweet) and 2 Way passive in the rear doors. That'll use up the 8 powered channels. The 9th low voltage sub out would need to go to a separate amp and a box in the trunk. I wouldn't add any more surrounds at first.
When you're tuning the Prima, and with an active set up in front you can tune each individual speaker for EQ, crossover, level and time correction) you'd repurpose the Frontbass speakers to function as true mid bass drivers, and smooth out the transition to the 4" mids. Since they tend to be bright, a little EQ helps take the edge off.
Then you'd tune the sub to start way down low and cut off where the Frontbass start coming in. You also might consider replacing the stock mid/tweet with the Focal KRS100 vs the "3D" tweets. They sound good, aren't power hogs, and the tweets are very nice, much smoother and cleaner than stock. No light show though 😕.
The other speakers (center dash and rear parcel shelf) that are orphaned on the Prima just leave on the factory amp and tune around them. The Prima has so much DSP it's very easy to blend everything in. That part always flips people out but I've done it now on two cars and I've never found it necessary to get into them.
Basically if you used the system in the 205 write up you'd be in good shape.

I figured they would not sound any worse or degrade the overall sound quality but I am surprised at how much better they sound over stock... it may be some placebo effect but I am VERY happy wih it






I totally agree with you on the looks of these speakers... they definitely add to the car and at $800 I found it to be worthwhile!

so did you retro fit the 3d amps or wire the 3d speakers to aftermarket amp? I'm in the process of doing my audio now and I can't decide what route to take.
