I use a REL Stentor III with my 802N's. Extremely fast and musical sub. B&W subs are really not what you would want.
How To Add A Sub To B&W N802's
I am thinking about buying one of the B&W 800 series subwoofers to my N802's. I honestly know nothing about how to go about this or if it is even a good idea? I thought about upgrading to bigger B&W's like the 801's but thought this might be an easier and cheaper route. Any advice on this at all?
