Hey everyone been a long time lurker and havnt posted much if at all. Apologies that the below has been repeated a few times but would really appreciate a fresh opinion from anyone willling to help. So I’ve recently moved House which is now detached and have a bigger space which I was able to fill with some goodies....wife approval of course. I’ve a 55” Samsung js8500 tv, Yamaha Rxa1700 aventage receiver, monitor audio bronze 5 floor and centre speakers with q acoustics 7000i rear speakers and two Cambridge audio c46 ceiling speakers. My room is about 2000 cubic feet leading into a room of 1200 cubic feet with wooden floors throughout.....which brings me to my query, best subwoofer I’m currently using my q acoustic 7070si which isn’t cutting it I’m afraid....I’ve only really one place I can put it due to the better half’s direction....space/budget wise I’ve narrowed down to these subwoofers. PSA s1500 SVS sb2000 XTZ 12.17 I’ve mostly swung towards the XTZ due to overall reviews and price but would push the boat out for the PSA if I thought it would have the extra performance for the diff in price. Any thoughts or experiences greatly appreciated. P.s can’t fit duels well could but cant lol. Thanks, Andy.
