How To Add A Sub To B&W N802's

Assuming you plan to use bass management (TACT, PARC or some such device for room modes) then go for it. I am not familiar with B&W subs and they may include thus feature.

Otherwise you may find room modes iompressive but too much for good two channel listening.

I use 803D mains and a B&W ASW825 sub with HTM2 center and 805s for the rears. This works very well for HT, but I run only the 803D for stereo and have been very satisfied with the base. Perhaps some speaker positioning or room adjustment/treatment could help? Also the B&W is a bit of a difficult load, especially the big guys like you have- maybe a bigger amp?

yeah I feel like I am missing that slam. I listen at very loud levels and my room is fairly big but who knows how long I will be in the same room. I read it is a good idea to get two subs for stereo listening but I really don't think I can do that finincially right now. I will only be using this for streo music by the way in case that helps with the replies. This is kind if embarrasing but I don't even know how you would hook up a sub, do you hook it up to the preamp or what?

Shadorne I do not even know what bass managment is. Honestly I never even though about a sub till recently but at first it seemed like a good idea instead of upgrading the speakers which would be very costly. The sub I am looking at retails at $3500.

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.
