B&W Nautilus Subwoofer to match N804s


I am slowly but surely building my complete Nautilus home theater system. Yes, I haven't eaten anything for a while, but it is worth it. I have purchased the N804s for left/right and the HTM-1 for center. Eventually I will buy two more N804s for the rear (or possibly upgrade to the N803 for the front). Anyway, other B&W owners, what sub do you have with your system? Does B&W make a worthy sub, or should I look to something else? My room is about 17x15, and the sub will be along the side wall, not in the corner. Thanks.

I am using the Vandersteen sub with my N804's in my 2 channel music system and have been very happy with the results. Really blends in nicely and fills out the rather lean and weak low end of the 804's. I use a HSU sub in my HT setup. I don't think that it is as good as the Vandy but you really can't beat it for the price.
I have the Nautilus 802's and htm1 and N805 for my rears. I use a asw 2500 but I would go with a REL.
You may not need a sub of much size if you use 803s instead of the uptilted 804s. But my take is from a 2 ch music perspective, not HT. Have fun.
Has anyone seen the new Martin Logan sub? I forget the model, but it has three 10" drivers and is shaped like a raised pentagon. Heard it the other day and it sounded just as good as the REL Stata.
i have the jm labs sw38a in my system with n804s. same bass driver as the wilson grand slams and very tight, controlled bass. watch the crossovers on whatever sub you get tho - let the n804s do what they can and just fill in the lowest lows with the sub (IMHO). enjoy. baz
