This is correct. No where near the same quality and no longer made in Germany.

The Q series used to be 'hand made' and were really hot stuff 7 plus years ago. Something about hand made German speakers just sound right for the shark.

I'm not looking for a set, but I figure there will be folks that are. So, I'll ask the question.

Now that MB Quarts suck.... any recommendations on speakers that don't look like they belong in the Fast and Furious, sound good, fit without needing a saws-all (or, like the MBQs come with trim rings OOTB?)

Ok, did that. Lowest cost MB Quart - $109. Blaupunkt with better specs - $39.

Next.

my 87 has mb Quartz all around, sound great but I'm not too keen on the look
on the doors of my 88 I have a set of Blaupunkt overdrive, this is a 2 in one tw/mid thinline speaker... a bit on the high side tone wise but with a good eq this shouldn't be a problem
below are 3 pics, 1st w/BP grill and 2nd/3rd after I adapted the 928 oem grills onto them (I have another pair of these new in the box if you're interested)

That looks better than my pimp-ride grills. I like it. I'm gonna work on the stock grills and make them fit over the speakers.

Ok, just for fun… free to a good home speakers (just pay shipping). REI 4.25 front Blaupunkt 6.5 coax rears.

I know they will fit the factory locations because they were in my car when I purchased. Used less than 6 months, but been in storage for 5 years.

They all worked when removed,,, I just need to make sure I haven’t already disposed of them. PM if interested.

rixter

fyi.. I cut the oem trim ring off the original speakers so the oem grill can screw on
I then mounted that ring over the trim ring on the new speakers when mounting to the car .... took about an hour per side including removing/replacing door panels to ensure fitment, so figure 30-40 minutes each, most of it adapting the ring

I modified my OB door panels with fiberglass, I have pics of the process if needed. Blaupunkt Velocity components 1.5 tweet, 4 " mid and 6" bass in lower panel. I also modifoed the rear qtrs to flush fit the components.

Very nice looking install! It that original leather? I’m a huge fan of burgundy interiors.

I'd love to see some picture of the fabrication process. I have a set of sixes I need to install low in the door. I want to do something like yours out of fiberglass.

Need to edit out the extra "http://" for the link to work

Hi Sterling,

Thanks for the link. I've seen those pictures in other threads, but not the commentary. Nice use of basal wood. Did you use glass matt in addition to balsa wood and resin?

The picture of the back side looks like the ring is flush with the original panel, yet on the other side it’s built out at least an inch. Is that volume filled with balsa wood or is the picture deceiving. I can’t imagine having a solid inch of material without it weighing a ton unless the gap is filed with balsa wood.

Do you happen to have any more images for other angles or earlier in the fab process?

Yeah, I love your interior - I think I saw it at the Shark breakfast. It all looks top notch, but what I discovered by accident while working in the car is that I like to rest my leg in that area where the 6 1/2" speaker goes.

Since you're local, where do you source your materials from, like the balsa wood in particular.

If you need grilles that look at home in a 928 a/d/s/ makes nice grills. They also now make pretty good speakers too - they used to make fantastic speakers but went the way of MBQuart (beat them to it in fact).... you can still sometimes buy the 'old school' units on ebay...

Example of the grilles on ebay

I actually have component sets in the doors with a/d/s/ grills on the 5 1/4" and stock Porsche grills on the tweeters, 6.5" a/d/s/ grills on the B pillar (with again stock tweeter grilles) and 3.5" a/d/s/ grills on the rear quarterpanels.

All my speakers are a/d/s/ but pretty sure the grills would work OK with other brands of same size too. The 6.5" are mounted on top of the factory profiled spacer rings - though I had to cover them (leather) to tidy them up (fit and spacer ring repair issues).

And actually normally you don't even see the speaker cones behind the grill - the camera pick it up more for some reason.

Spacer ring on the rear quarterpanels is because the depth is very challenged there - no decent speakers seemed to fit 1/4" more makes all the difference.

Here are some basics on my door panel mods.

A. Upper Section: ( see pics below )
1. For the upper panel, made a plate out of mdf for the 2 upper components and beveled the edges to match the edges of the exsisting panel.
2. Glued the plates in place with construction adhesive and secured from back until glue was dry.
3. 2 layers of fiberglass matt and resin to blend into the panel
4. Sand smooth and skim coat with plastic filler and shape to preference.
5. Add 1/4 padding underneathe and cover with leather.

B. Lower Section: ( see pics below )
1. Used a pre-made 6.5" speaker mounting ring ( available on e-bay and audio stores ) mount in perfered position in front lower corner of panel. Make sure there is enough clearence in the front and lower edges in the door sill. They just need to be tacked into pace. The fiberglass will hold it in its propper position.
2. Use the expanding foam insulation and fill all of the area that needs to become part of the shape. let dry 24 hours. Shape and contour to preference..I used a hand saw blade to shape things initally and finished the closer edges with coarse sand paper...you may also end up with some large pitted areas. Just hit them again with the expanding foam and shape to taste.
3, IMPORTANT: You cannot apply the fiberglass directly to the foam. It will melt the foam underneath. You must cover the foam area with either a few layers of a latex paint or similar material. I used a layer of packing tape over the foam areas, making sure the wood areas were still exposed to bod with the fiberglass. Please see the 3 and 4 pics. You can see the tape through the resin. ( the best tape I found to use was the silver flexable duct work tape used in home HVAC systems )
4 Covered new area with 2 layers of chop matt and resin. Sanded and recoated in needed areas. Skim coated with plastic filler and sanded to shape.
5. covered with matching carpet.

I hope this is of help, I do have more photos of the recovering process also.

Yep Alan good looking grills.
