I love this subwoofer, so I bought another one and a Harman Kardon 3490 stereo receiver that supports two subs

Just pure, clean stereo using a high powered receiver, A/B (two pairs) of large floor standing speakers and this awesome sub made by Theater Solutions

In years past, most products would show up in audio hi fidelity stereo magazines with reviews that would really showcase the pros and cons of equipment, now it seems that this is just an outlet for advertizing of products that buy advertizing.

so i bought this and it fits the stereo now perfect nice and loud with hard thumping bass
