Shhhhhh Don't tell my wife. Looking at B&W 802Ns

Depends how YOU talk to THEM!
Appears that your room is long enough for proper coherence of these drivers. Just make sure you don't sit in the nearfield...HER'S either for awhile!
And NO, they don't sound AT ALL like 804s to me....have fun.
(MY wife thought the N802 looked like Darth Vader trying to sneak into a convent! Ha! She also thought Disney designed the Revel Salons....)

You *just* get by size-wise; a little room treatment on side walls wouldn't hurt the sound (but that's stretching the waf, isn't it?). Otherwise, I'm not sure you can get 10 b/ween the speakers--too close to side walls? Just to be on the safe side, ask Rives about treatment b/ween the speakers.
WAF: Try showing her a pair of big Apogees first -- by comparison, the B&W's look normal...
(My wife thinks Duevels look like an old laundry machine with a traditional chinese cap on it, & Apogees belong to a construction site.)

Hey - we won't tell her if you don't! Install 'em while she's out, and just wait and see how long it takes her to notice the change on her own. I wouldn't say anything - just have some of her favorite music playing when she gets home!

My wife loves them and I just had to have them. I did a 10 hour round trip selling my 801 III's and buying my N802's. My wifes words were "they are fabulous" as we sat and listened. They are a much improvement on an already great speaker. We just love the looks, and the HTM1 center is a huge improvement and awesome match in the theater. Gotta love 'em and happy listening!

Put whatever your wife loves in a box; right next to your system. Whatever it costs. Consider it part of the price of your speakers. It's always helped me. Good luck.
