I would have to say Focal, MB Quart, Diamond, and Boston are all great. I have even heard JL Audio's ZR series, and Polks new SR series and they sound good to. I'm currently using Polk/Momo 6.5 Component set F and R in my accord. My car is fully matted with Dynamat and Dynaliner as well, and it sounds great. I love the old Boston Pro Series components (all black set) those were some of the best to me. Focals best sets are the Utopia Be series and K2 series IMO.
