Hi I'm looking to pick-up a second hand sub-woofer to go with my current setup and would appreciate some advice. I live in a mid terrace house and have drawn a rather childish diagram to show the layout and sizes. Its mainly used to watch movies/tv shows and now again I'll play music like Nightwish/Xandria/Collide/Android lust through it. AV Receiver: Onkyo TX-NR609 Front: Cambridge Audio S70 Rear: Cambridge Audio S20 Centre: Cambridge Audio S50 I've been thinking something like the Wharf SW150. Buying second hand I don't really fancy spending more than £180 perhaps. I've only just started looking at woofers today so I'm not really quite sure what I should be looking for in terms of spec.
