Summary:
I have a pair MB Quart 5.25 QM Speaker's in my 1998 Volvo S70 supported by a pair MB Quart 8" Reference Midbass speakers. Let me tell you these speakers kick ass!!! Tweeters nice and defined. Awesome off axis response. You can hear everything in the music Nothing left in the shadows. The speakers are very clear and articulate.

Strengths:
Bold in your face speakers!!! Blend in well with 8" inch midbass's ( make sure you have them crossed over correctly)

Weaknesses:
Can be a just a very very and I do mean very tad bit abrassive on the treble side, but nothing to impair your enjoyment of the listening experience. Barely any weaknesses.

Summary:
I got these as a Christmas gift and they revolutionized the way I listen to music. I have a pair of the 215.61 powered by a Nakamichi PA1002 with QSD 4" components in the reaer powered by a different PA1002. My head unit is an Alpine 7998 and I have a Focal Utopia sub powered by an arc audio amp. I love my setup, I drove for over a year with nothing except the front Q's and the nak amp and it sounded great. The tweeters are bright but after reading other reviews and turning the crossover to -6 on the tweeter they sound amazing. I love these so much that I bought the S1030 home speakers for my stereo and they rock as well. The clarity of these speakers is unrivaled and when installed properly (dynamat and good wires!) the bass response is very true to source. Imaging is outstanding and the speakers seem to be able to handle all the power my amp can throw at them. I keep the gain set in the middle so as to avoid noise but even with the head unit turned to the max these babies show no sign of giving up or distorting.

Strengths:
Power handling, clarity, imaging, bass response

Weaknesses:
none

Summary:
These speakers are truly beautiful. I have 2 pairs in my 300M with a JL 300x4 amp. Anyone who claims MB Quart's tweeters are harsh had them improperly installed. Done correctly these speakers are perfect!

The clarity at high power.

Summary:
These are amazing speakers. I have the 215 5 1/4 inch model and they put out as much mid bass as my 6 1/2 inch focal polykevlars (maybe more). They are every bit as good as the polykevlars and probably then some. I think they are rivaled only by the Focal Utopia, high-end ADS, and Dynaudio. They are one of the finest set of car speakers money can buy. The imaging is unbelievable. I too set my crossovers to -6db. The tweeters on this setting are perfect and not overly bright. I am told this is the proper setting for a single mid driver. I have no choice but to give them my highest recommendation. You can''t go wrong.

Summary:
Wonderful speakers. The first thing that becomes obvious when listening for Q''s is the abundant midbass. The 215.61 set puts out far more midbass than other 6.5" speakers. Tweeter does need to be tuned, but when it is tuned, the upper range is far more accurate out of the titanium dome that other soft domes on the market. Wonderful imaging and depth. Very transparent and take power well. I have had Focal Utopia''s.... They DON''T compare. Midbass is non existant in Focal.

Strengths:
midbass, imaging, dynamic capability.

Weaknesses:
tweeter needs to be tuned down.
