UPS man delivered my Xsub today. First impressoin ... WOW. Very nice sounds. Let me start by saying that my HT is still in pieces and mostly in my office and un-calibrated. So I quick hooked up the Xsub to my Marantz SR8400 and paired it with a set of Axiom M22Tis. I quickly hooked up the sub via the LFE (is this better then using the speaker wires? The Xsub has two LFE inputs and I am supposed to use an RCA splitter if my receiver has only one LFE out. I used no splitter and hooked to only one input on the Xsub). So with no calibration and no surround sound, I still have to say that I loved the sub. Perhaps there was a bit more ... boom ... then I would have liked, but I wont judge it will I have it sitting in my HT and properly hooked up.
For $250, I think its a pretty damn good deal.
