Hi guys, looking to add a sub to my system, for some reason I want to go for a Yamaha one 'cause it may fit with my DSP-A5 well? Also I like the "look" of the Yamaha subs. My budget is up to £150. The SW215 seems to fit the bill, I'm not looking for gut wrenching bass, just something which adds a bit more slam to movies and fills bass out on music. Not read any reviews but usually Yamaha subs don't get reviewed well vs the smaller niche companies. Has anyone got this or have had first hand experience? Thanks...PJ PS the DSP-A5 has single phono out to sub - is this standard?
