Hi everyone!! Just wondered if i could have a few reccomendations for a new sub, i currently have a ****ty gale sub which i nicked off my dad (i think he got it from RS for £100) and i'm sure it can't be doing my system justice, i currently have a marantz 4200, celestion f series speakers and about 300 to 400 quid to play with. Also, does an expensive sub really add anything to the whole surround sound dvd experience? I dont know coz i havent listened to any other sub, please help me ANYONE!!!
