I got a set of MB Quart component autosound speakers, their TOTL set from a previous era. MB Quart RSB 335 consists of 8" woofer, 5" midrange and 0.75" tweeter, along with crossover. Crossovers looked to be high quality- all film caps, etc.The 8 inch woofers have a high QTS - 0.99
So, rather than put these in my car I had a a set of transmission line cabinets made based on the classic Daline design. I did not do any calculation, I just widened the cabinets a little to allow mounting the 3 drivers. I progressively packed the line with acousta-stuff, and used a sealed subenclosure for the midrange well stuffed with it.
They sound VERY GOOD. Mids are a bit forward- pleasantly so, and bass is very tuneful, solid, taut and has a bit more extension than you'd expect from an 8 inch driver.

Car stereo, yeah, not an exact science. Some cars have speaker placement which is not too bad, in other cars it's clearly an afterthought. A skilled autosound shop can try to make the best of it, but buyers of aftermarket car audio tend to want loud, boomy, LOUD and bright systems. It's the rare car audio retrofit that is aimed at better imaging, coherence, detail....There are a number of luxury or near-luxury autos that have put a lot of engineering and consideration into their sound systems. The "ELS" systems in today's Acura models are really pretty excellent; the Mark Levinson (Harmon International) systems in Lexus cars sound very good. Even some of the Bose-engineered systems are decent- I have an Infiniti G37 and it's Bose system has good imaging and is decently balanced- sounds very good on classical, acoustic jazz and folk- the Bose engineer who designed it a violinist. Wes Philips of Stereophile even reviewed the setup, see http://www.stereophile.com/news/071706infiniti/ This Infiniti Bose system, however, leaves most hip-hop and pop listeners cold.
Interestingly, some high-end cars seemingly just slap big audio names into their cars without the real acoustic engineering needed to make them sound anything like realistic on music. For example, the B&W system in 2010-era Jaguars is not considered top-notch, the B&O system in Aston Martins is said to be lacking and many of the other Bose systems out there in BMW's are not all that great (though better than "stock" audio)

Well, on the one hand you can make crap and you'll probably sell a ton. Remember those 6x9's with 3 or 4 different tweeters mounted on the pole?
On the other hand, imagine building a speaker when you have no control over the cabinet. It'll probably be made of rattling pieces of thin metal and plastic. In addition, your speakers are probably going to fire into someone's calf, or a piece of glass 6" away. Oh, and they need to sound as good at freezing temperatures as they do on broil. Basically, you have to say, "We spent countless hours perfecting this in the lab, now go f**k it up with your installation."
So true -Bry
here in the deep South, higher humidity, did not fare well for MB Quart speakers. I was thinking about this very subject very recently. Living out some fond memories I guess you could say. Anyhow, in the early 90's
Sony (not Sony ES) made some very generic looking car audio speakers
separate tweeter and 4 1/2 in midband driver. I can attest that these were very fine sounding speakers, inexpensive compared to the competition, as well.
Easily on par w/ Polk Audio and Boston Acoustics competition series.
Sounded as good as MB Quart to boot.
Road and engine noise should be a dead give away that fine audio in a car is not going to happen.
But I always did like to play "what's that kid listening too" as I hear boom, thud, boom, thud, thud, boom coming from a car driving down the road that I can hear from inside my HOUSE with my stereo on !!!
I'm not sure I'd want to do the research it would take to get any good at that game.
I've always felt that the people in the best position to make car stereo sound good are at the factory because they can devote time to tailoring the system to that particular environment. Unfortunately, that's something that rarely happens (or happens well). It's also getting much harder to replace a factory stereo that's built into the same plastic as half the dash and communicates with all the other electronics in the car.
Anyway, it was a fun hobby when I was younger but it was always hit-or-miss. I don't know if I'd ever devote the same time and energy to an installation today.
...with a Burmester system built it.
My '04 Cayenne had a Bose surround system that sounded pretty good. My current '13 Jeep Grand Cherokee Ltd. had a 10-driver system that was so hard and screetchy sounding I ripped most of it out.

Cool project- no doubt. Back in the day I preferred Oz Audio speakers over MB Quart.
Very nice job there. The only thing I'd have doubts about is the
tweeter used. I'd probably go with a silk dome or possibly a good
aluminum dome, but not Ti.
Yeah I just used what came in the kit. Sounds pretty good, actually. Not tizzy.
