This is my first post so Hello! I've been considering a new sub to complete my Home Cinema. I've been considering either YAMAHA YST-SW105 SUBWOOFER or SONY SA-WM20B SUBWOOFER I've found numerous reviews but none of them conclusive. I want to spend about £100-£150 so can anyone recommend either of these or alternate for around the same price range. I don't need it to go that loud but I would like it quite deep.
