Thanks to all of you here who already have SVS subs,I've finally got round to buying one,and the PC-Ultra arrived yesterday. It's not been properly setup yet,other than level matching etc and a bit of fiddling with the PEQ,but what an improvement over it's predecessor. As someone who's had a decent set of full range(Linn Keltiks)speakers previously,finally we've got back to the bass depth and control we had previously,but without any of the room matching problems. It actually got everyone's feet tapping,and not one soggy note around......more when it's fully done. The title of thread refers to the fact that although it's in the lounge,working,and better than any previous sub we've had in there,my wife hasn't found it yet(yes....it surprised me as well!)....she will this morning when she goes behind the ESLs to open the lounge curtains....so there's how to hide a 1 cubic metre cylinder in your lounge....behind a set of old Quads. Also a word of thanks to Ron and Erik at SVS for their advice,and their superb service....from order to delivery it took under 7 days....quite amazing.
