I am actually interested in sound quality and matching the best sub to the amp I already own (infinity 1211a). The rest of the components I am running is the Infinity Reference Components (6.5 inch and tweeter), and Kappa 6*9's which are powered by an Infinity 7541a (Channel 111 Watts RMS per channel) amp. So it is an entry level system I guess..not high end by any means but decent enough.

As for price well..let's say under $1500 for two subs? Is that reasonable?

Does anyone have a take on the Kicker Comp VX subs versus Alprine Type X (sound quality)? Would 650 RMS per sub be enough to actually power the Kicker Comp VX decently?

If I decided to just go for base the DS12L5 would seem like a good option. (Kicker sub box and two S12L5 Subs). How are the boxes made by the speaker company themselves?

Thanks for all your help again and putting my endless questions..I appreciate it.
