Infinity Kappa 693.7i

These speakers are truly a completely satisfaction. Has a real nice sound, crispy and clear highs, and they are powerful too! I have to mention that I never, by rule, I never run any speaker with bass or low frequency, because the speakers of this kind I think they aren´t made designed for this use, so, I don´t know if the speaker can support an strong bass, but I don´t care (I have a couple of very good subs), these speakers works pretty nice well!

These speakers do a great job filling in the rear end in my car. I like the option to boost the tweeter, even though it does sound a little harsh so I've refrained from using it. Only running them off head unit power right now, they could definitely use a speaker amplifier because they sound a little weak. Cranked all the way up though, the still sound crystal clear. I used some rubber sealant (easy to remove, don't worry, my speakers aren't glued to my rear deck) in between the speakers and the rear deck and I get absolutely no rattle. If I knew about SonicElectronix before I wouldn't have paid more and bought them retail :(

I have these 6 x 9's along with the Infinity Kappa 63.7i 6 1/2's and this set rocks. Listening to these on my system without an amp can hurt your ears after listening to music for 15 minutes. The treble is extremely clear however the bass can get a little off after putting the volume near max. I suggest adding a little amp to bring the full bass potential out in these speakers.

i bought these a day ago just getting them worked in and they bump hooked up to a kenwood 2 chan amp not even half way up

I bought these speakers on a recomendation from a friend and i absolutely love them they have great sound and were really quite easy to install. Plus they look great it's almost a shame to hide them behind the door panels
