big screen - two channel system enough for dialog?

There is NO question that a proper center channel speaker will enhance dialog intelligibility. Keep in mind that the center channel is THE primary channel used by the audio guys when mixing for movies. Additionally, it "anchors" the sound to the center for those viewers who are off-axis and not in the sweet-spot.

So, don't cheap-out on the center channel. *Most* mfgrs. nowadays make a center channel that is complementary to their main channel offerings.

I currently run Gallo Reference 3.1s for my main L/R, Gallo Ref. AV Center for my Center, and Gallo Ref. AV for my surrounds. My sound is *superb*, and the 60 inch Mitsu DLP HDTV suits my needs for the moment. But I dream of a 92" Mitsu DLP sometime in my future...

No offense, dude, but that room looks like a standing wave nightmare. I would *seriously consider placing some sound damping materials on the side walls near the 1st reflection points. Additionally, some thick, sound damping carpets would go a long ways towards killing the floor to ceiling reflection points.

But, other than that, it is one *hell* of a nice room for a home theater, ya oughta be charging admission. And hey, I need a gig right now, gimme one of those ticket-taker monkey suits with the pillbox hat and I'm yer boy!!

I am sorry I did not read all of your posts thoroughly. Since you have the luxury of building the room, by all means take advanatge of the abilitiy to make the side walls and ceiling non-parallel. This will effedctively kill any standing waves in the room and largely eliminate nulls and voids in the rooms frequency response. If you have the money for it ($2k-$5k), I would *highly recoommend you employ the services of a firm such as Rives Audio. They are *experts* in such things and will give you invaluable information on the proper design and construction of a terrififc looking and sounding HT room.

Man, I wish I was in your shoes, you are one lucky man!!!

10m ceiling is hard to manage for music indeed.

Rlwainwright,

did you mean Mitch4t's 22 ft wide, 70 ft long and 22 feet high room?

What makes this a standing wave problem, the relative proportions or absolute size??

My room is about 17' x 30' x 10'. It's also irregular (about 15' along the long wall the wall jogs in maybe 4' and widens). Will this be a problem??

I have yet to sheetrock it so I can make tweaks if necessary.
