I am wanting to upgrade from B&W 603s3 mains because they just aren't capable of filling the room up in which they are now placed. But I also have dual SVS 12 inch sealed subs that I love. I am wondering if the subs with the Triton 2s would be redundant. I am pushing the system (B&W center and surrounds) with a Marantz SR7007. I know I will have to replace the whole set up due to changes in tonality in the speakers so this is pretty important. Would dual subs be pointless?
Thanks

Some great scholar once said, "there's no such thing as too much bass".

Keep the subs! If they are positioned in the front of the room, use them to give the T2's more LF dynamic range (set T2's to Small with maybe a 40-60Hz crossover). If subs are not up front, use them as LFE-only subs (T2's set to Large) to give the system improved dynamics for movies.
