Got a boxed set of aelites in my 30x15 lounge - consisting floorstanders, series 2 rears and the centre. Am hopefully collecting a denon avc-a11 tomorrow. The question being what sub should I purchase in the £800-£1200 range to complement the above? It will be used on a 80/20 basis in favour of home cinema. Thanks for taking the time to read this and hopefully respond.
