Hi guys - My first post on here!!! I'm thinking of getting a new sub and was wondering if anyone can help with any ideas? I'm not really looking to go too far over £350. (But I guess you've heard that before ) Does anyone have any experience with the Yamaha YST-SW320 or Definitive Technology Pro Sub 80? I tried the MJ Accoustics Pro 50 (I think) and found it to be abit 'small' Any help is greatly appreciated. Thanks, Martyn.
