Advice please: Surround choices for my room

803 Views 1 Reply 2 Participants Last post by  m_vanmeter
My smallish room is 17 x 13 x 9 and I am planning an all inwall system for 100% theater use. There will be one row of seats (a very wide couch, actually) that puts the viewer's heads approximately 15 feet from the front wall and 2 to 2.5 feet from the rear wall. The viewers on the outside ends of the couch will have their heads approximately 2 feet from the side walls.

I am pretty set on the klipsch KL-7800 thx in walls for the front LCR behind an acoustically transparent screen due to the fact that they have an integrated enclosure and I like the dynamic horn sound for home theater. If it matters, sub will probably be the new Elemental Designs A7s-650 or two SVS ultra cylinders (either choice would be nearfield behind the couch)

Based on this information, which of the following would you choose and why?

1) matching klipsch KS-7800 thx surround (uses "Wide Dispersion Surround Technology" which seems to be a bipole surround) in a 5.1 config with the surrounds slightly behind the viewer at the dolby spec location at 110 degrees.

advantage: matching horns, somewhat minimize problem of being too close to the surrounds

disadvantage: still too close to surrounds to use a bipole configuration?, no rear surround speakers

2) a true dipole inwall surround for both rear and side surrounds in the dolby spec 7.1 locations

advantage: dipole mitigates being too close to surround locations, 7.1 future proof

disadvantage: non matching surrounds (and really non matching because fronts are horn tweeters)


I guess a third option is something like the emotiva erd-1 surrounds that can be bipole or dipole so I can experiment with them to see what sounds better. Of course they would not sonically match either and I would lose the all in wall aesthetic (although they are only 4 inches deep).

Any other suggestions would also be appreciated.

a suggestion for 5.1 - use dipole speakers to diffuse the sound, set at 110 degrees as you mentioned.

for 7.1 use dipole sides and monopole rears, but with pivoting tweeters to ain

more or less towards the center listening area.
