Tks for the input, Takeereasy. You've affirmed my main concern, which was that the Mirage system would not have the balls to hold to is this room. Basically, I've also figured out that the dealer pretty much wasn't listening to what I was saying with regards to room size and was pretty much set on a one-size-fits-all answer, so I'm back to square one.
As far as budget, I didn't start off with posting it as I first wanted to get any feedback on the Mirage in general and specifically its use in my application. I'm not setting a "hard" number, but I'm aiming for staying ~$1000US/pr for fronts, up to another $1000 for subs, and up to $500 for a timbre-matched center, then pretty moderate for 4 surrounds to finish out a 7.1(or 2) system.
The big issue in my case is getting a workable solution for side surrounds. Because of ventilation ductwork and pipes, the almost 8' ceiling in the basement bumps down to 82" high from the back wall of the HT area out 6'. Wer'e doing 2 rows of seating, so the back row will be completely under this bump-down, while the front (primary LP) row will start then at 7' from the back wall. This creates a big problem for side surrounds . . . if ceiling mounted in front of the bump-down, the side surrounds are completely occluded from the back row--not acceptable. This leaves us with ceiling mounting in the bump-down; since it's only 82" high, anything that hangs down more than 6" or so is going to become a head-strike hazard in two main walking paths. That's how I ended up looking at Mirage--the OmniCans offered a workable option for the side surrounds and allowed use of identical drivers (regular OmniSats) wall-mounted for the rear surrounds. For the rears we're locked into a back wall surface mount, so going with traditional in-ceiling speaks for both sides and rears won't fly, either.
ANY ideas for dealing with this surround issue other than Mirage would be greatly appreciated!
Actually, I talked at length with an HT enthusiast/salesman out at Nebraska Furniture Mart today while we were ordering seating. I told him my issue, and he also had serious doubts about running the Mirage kit in my room. He actually referred me out to much more "serious" sound shop and suggested I take a listen to NHT's Super Audio and Evolution lines. He contended that the NHT's were sonically compatible with the Mirage OmniSats and suggested that I might stay with the Omnisats for my surrounds but go with the much more full-throated NHT's for fronts and center. But he also suggested that I might want to consider beefier surround options . . .
Thoughts on this?
As to subs . . . the Hsu VTF-3 MkII is on my "short list" . . . will one be sufficient to pressurize my room? If not, I was considering pairs of either Outlaw LFM-1's, Hsu VTF-2's/STF-3's, or Rocket UFW-10's. I know that these pairs don't extend down as low, but they offer more air movement than any single sub I can afford (the Velo DD's are regrettably out of my range!).
Would the VTF-3 MkII hold its own in my room if I go with more full-range towers for my fronts?
