i am running infinity kappa 63.5i's in the front and refrence in the rears both driven from my kenwood amp (60W rms a channel) and they sound freaking incredible i thought the refrances were ok when they were up front but its a world of difference, im picking up little details in my music that i have never heard before and i have the logitech z560's on my computer which are really great speakers but there even no comparison. now i just have to decide which infinity sub to use, the perfect 10.1 or the perfect VQ, any advice?
