MB Quart sound quality
Just had some MBQuart PSD216's installed in my C5.
They are 6.5" 2 speaker components. Amp is Precision Power PCX-5800. JL Audio sub in the rear. Speakers sound a little muddy to me. Anyone compared these the Q series by MB Quart?

Re: MB Quart sound quality (MrVegas)
I'd say it's the install. MB Quartz makes one of the best sounding sets I listned to while high-end shopping. Do you have them crossed over at 70hz? My Focal Utopias sounded muddy until I set a high pass filter at 70hz on 'em. What kind of power are you running? How are your tweeters set up? They should be unobstructed and facing the opposite seat.

Re: MB Quart sound quality (Kale)
Kale... I think the power is OK as well as tweeter placement. I'm curious about the 70hz high pass filter. What does that do? Cut out certain frequencies? Can that stuff be adjusted on the Quart crossovers?
Thanks a million for your help.
Also, certain hi-fi gear needs some *burn-in* time. Perhaps my amp and speakers need some time for that also.

Re: MB Quart sound quality (MrVegas)
The PSDs are a lower end MB Quart. Their best speakers are the Q series like the QM and QSD. The best solutions for muddy sound are tweeter placement and blocking low frequencies. As long as you are using the MB crossovers, you should be ok with respect to tweeter frequencies. I don't think though the crossovers block low bass to the mids and tweets. If you are running these speakers full range, meaning all frequencies are going to the amp and the amp is putting the full range of frequencies to the MB crossover, the woofer/mid of the MBs may be trying to make deep bass which will keep it from making as much mid as it should. It sounds instead like you have highs problems. The only solution for highs is tweeter placement or replacement with better tweets. Also, check to make sure that all speakers are wired properly +/- as if one is wired backwards the speaker will pull instead of push and it ends up fighting and canceling out to some extent the other speaker.

Re: MB Quart sound quality (92TripleBlack)
a high pass filter cuts out frequencies about x,
a 70hz high pass will prevent the speaker from playing lower than 70hz frequencies. Your 6.5's can't reproduce those sounds properly, anyway.
A good amp should have a built in adustable crossover. If not, you can use
in-line filters called "F-Mods"

A good crossover will only have about -12db/octive. Your best bet is by using electronic filtering with your head unit or amp, whichever is applicable. These will typically provide -18 db/octive. Check your head unit features and amp crossover points. You may simply need to dial things in.

Re: MB Quart sound quality (Kale)
If you can afford a C5 and MB Quarts, don't waste your money on F-mods! :bs Either get a head unit, EQ, or amp and dial it in. :smash: :smash: :smash:

Re: MB Quart sound quality (MrVegas)
You may have a problem with the way the drivers are mounted. Make sure they are not directing energy into the door panels. This can make them sound that way. MBQ's are traditionaly "bright" and should not be muddy at all. Also ensure that they are in phase. Hard to get out-of-phase with these speakers as they are keyed. The larger of the spade lugs is the positive side.
