I have gone heard a lot of component speakers MB Quart, JL, Fosgate (suck), Kenwood, Sony, Polk, Orion, Eclipse, Alpine, Clarion, and a few others. These speakers blew them all away. Rich, smooth, and clear. Some say overly bright but they don't realize there is a tweeter adjustment to back it down. I personally think they sound near perfect at any setting but for the best sound you have to adjust in car for best results. Unfortunately I couldn't justify $450 speakers so I went with the rally 6's which were great but I soon became a REAL CAR AUDIO GUY and went with pro 12.5 subs and the pro 6.5's among other upgrades. And all I can say is WOW, if you really care about your car audio sound quality these speakers are it.

Unparalleled sound quality.Unparalleled clarity.
Too expensive.

These speakers will blow away and MB Quart, eclipse, rockford, DEI, polk, etc etc in terms of sound quality. They have plenty of power handling too if you want to go deaf.

5 for sound quality.
4 for price.

Boston Acoustic Pro series are GREAT sounding speakers for the price, but if u are trying to compare those to the MB QUART Q Series, u shouldnt even try, the MB QUART Q Series are much more expensive, if u first look at both the pro series and the q series, you will understand why the Q series by MB QUART are much more expensive, the craftsmanship of the speaker is just amazing, and if u compare the two in sound quality and if both are hooked to a quality amp with a quality install, the Q Series imaging and the detailed sound overcasts the Pro series with ease. But hey, im not knockin Boston Pro's, they sound good, and for the price, i think its worth it, though u can get it for much much less than the retail price

One of the best sounding separates I have heard. I spent at least a month auditioning speakers, and the only comparable model to the 6.5's I heard was Diamond's Hex series (regrettably, I never got to hear ads's 326i model). Very smooth and clear on the high end, rich and full on the low end. The diamonds may have had a slight advantage in the midrange (the 6.5's were just a little flatter ), but I was sold on how the 6.5's were put together. Installation was a snap. You can mount the tweeter on-axis with the woofer (for those of you squeamish about cutting into your door panels), and the bracket bolted right into my car's existing speaker holes.

crystal clear, absolutely no distortion at highest setting, good base when set properly

can't think of any yet

I reviewed speakers in this price range for about 1 month before deciding to go with these in the front, rally's in the rear, JBL sub connected to a panasonic 9000 DVD in dash, xtant 603. This set up sends chills up my spine,great sound accross all ranges. I would recommend to anyone but need good amplification and system to maximize potential.
