I have 2 sets of KFC-X178 (28hz - 25khz) running off an HU without an amp and they sound decent.. Not competition level, but decent. They have nice bass and seem to be clean. They have a large magnet and are built very well.
Instead of going hog wild on a system now, I was thinking about them instead of maybe the CDT CL series due to the ability to go lower in the freq range.
kenwoods to be were very overemphasized in the midbass section. My old manager at the shop tried the flagship set since he could get the cheap through comp and they were good but not as musically inclined as say the JL XR series. Midbass was better but overall SQ was not compared to the JL.
ok, but the emotional series are well engineered and its the excelon version here in the u.s. , you will have to import it from japan, because they will never release it out here, also you can try the xxv o4s which they would have on ebay, and now if you want to go pioneer, then i highly recommend the ts-p720prs comps
