Differences between BW N804 and BW N805?

Yes, without a doubt(and I've sold Nautilus/matrix myself) the 804N's are better than the 805N's, yes!!! Better bass, better top to bottom sound, everything! Also, you can biamp the 804's for supber results if done right..yielding an evem much much more dynamically tranparent and effortless full range sound(won't really work with 805n's).
The 804's end up winning in just about every aspect pertinent, and are worth the extra money in my experience.
Get em if you can afford the price increase.

I was talking about the Nautilus series, as I've never heard the Matrix series.

Lthkeeper, did you hear the N804 vs the N805 side by side the same day/same system?

And you can successfully Bi-amp the 805.

IF you're saying that the $3500 804 are worth the additional $1500 over the 805, well, I must respectfully disagree.

I still say that if the 805 don't do it for you, (about the only complaint possible is bass response), a REL Strata sub for $1500 retail will give you real bass response, not just a 9 db lower -3db point.

Plus, you probably will have to use a strong solid state amp to drive the 804, whereas the 805 can actually use and benefit from a tube amp and the REL subwoofers have their own amp built in...

Anyway, whatever you choose, try to hear both side by side, and take into consideration the distance from the speakers that your primary listening position will be.IF it's 7 feet or less, the 804s probably won't sound properly integrated, top to bottom.

Also, if you go with the 805, dont use the B&W stands, they kinda suck.

I would suggest the Osiris stands (you can get from Sigsound.com and avalonav.com)
I have dealt with both, fine gentlemen, the both)

Depending on your seat height, you MAY want to get the 21.5" stands, as I found that the 24" stnads were too high for me.

happy listening!

Thanks all for the responses. Chazzbo, you recommend the REVEL M20's and say they are different to the N805. What are those differences? Thanks again.

No Contest! With the right electronics, there is a huge difference. The n805 is just a monitor, better suited to HT imo. But the 804 is a good stand alone speaker, better depth, range, sound stage. For the price of the 805, you're better off putting that $ into a better speaker. If you don't like the 804, there are plenty of other good speakers in the same price range.

Revel M20's well it'sbeen a while but they seem to have a dryer presentation that isn't flat.Tweeter adjustment is added plus.But the 805's are able (with power) to go a bit lower with more slam I am just not sure if they are as flat as Revel's.Hey in this price range Maggie 1.6's if I had a dedicated room and add a subb latter well that maybe way to.Also and I hope ragu is listening the Audio Physic Sparks are KILLER for the $2K range.But me well if I was doing HT 805's would fit a sane budget but if I could clock some overtime at work I'd buy a used set of 803N's for $3500.Itergrated from top to bottom with beautiful deep soundstage and good imaging.I think that 805's @$2K and 803's@$5K list are the winners.But the 804 as I mentioned before is a nice spaker where in the old series the two middle speakers (804 and 803 Matrix made up until three years ago) weren't wothy of consideration.
