BW 9NT or Nautilus 804

Hello, I have a chance to pick up a set of Nautilus 804's for slightly more than the 9nt's cost. However I have heard there is really little difference is quality but a huge difference in cost. Any comments?
The biggest difference is the matrix cabinet in the Nautilus.
I'd advise the 804's. On cabinet alone, these speakers are superior. I am a huge fan of the CDM series ... but after spending a day with the 804s I have a new cookoie jar started ... You're right about cost, but these speakers have it all.
804's clearly have it over the 9NT. Not close, IMO. Not that the 9NT is a bad speaker, but the 804's do everything better.
