Actually small apartment house unsuitable (about controller position 30 overcomes one floor of a recent building, old building accordingly pessimistic), in my concrete application relined the Hochglanzklarlack pyramid the Sound Projector Yamaha YSP-5000 and does the job grandiose, depending on the application gently anschiebend to brachial, regal staggering.
If you buy one, then should be for all time the Subwoofer confidence.
Must not go unmentioned is then no smaller subwoofer Yamaha that afford similar for half to one-third of the purchase price.
That would be the reason purchases.
Once in a Lifetime is unreasonable in the subwoofer question and the monster in the living room, the better it can not draw the conclusion.
All thumbs up, great cinema
