Front: Klipsch RF-7 II
Front high/wide: Klipsch RB-81 II
Surround sound: Klipsch RS-62 II (2 sets in parallel @4ohm
s) - placed on the walls about 10ft apart in between tiers
Rear SS : Klipsch RS-62 II or Klipsch RB-81 - place on back wall
Projector: Epson powerlite 5030UB (then upgrade to 4k projector later on)
Fixed Screen: Elite screen or monoprice screen (HD white)
Fiber optic ceiling star boards (not sure how yet)
Chairs: Palliser Rhumba (black)
I have done regular living room (18x15 room) 7.1 before but never anything this large. The room isnt built yet because i dont know placement and really still planning
That Pioneer SC-79 looks like a VERY nice Home Theater receiver. However, even with it's THX Ultra2 certification, it is only THX certified for Reference Level, (RL), in 3,000 cubic feet of space, at a listening distance of 12 feet. http://www.thx.com/consumer/home-entertainment/home-theater/thx-certification-performance-categories/
That's great but... you have 10,500
cubic feet of space to fill, or more than 3.5 times the space that the THX certification applies to. You are listening anywhere from 17 to 25 to 33 feet away. The Inverse Square Law dictates the available headroom at those listening distances. http://hyperphysics.phy-astr.gsu.edu/hbase/acoustic/invsqs.html
IOW, figure 6 to 12 dB of additional loss for the increased distances.
That receiver would wok great in a room 1/3 the size of the room you're planning, or about 3,500 cubic feet of space. A 3,500 cubic foot room is still a very *large* room, bigger even than the THX spec'd room.
However, in your 10,500
cubic foot room... that receiver would be... hmmmmm... can you say "dwarfed" "overwhelmed" "out of it's element", etc.???
The Klipsch RF-7's are GREAT speakers. They're high-sensitivity, high power handling speakers. However, as good as they are, they're not even THX certified. To get to THX certification in the Klipsch line, you need to go to their THX U2 line. Even then, their THX speakers are only certified to get to RL in 3,000 cubic feet, at 12 feet away. As capable as the U2's are, they would really struggle with full Reference Level in a 10,500
cubic foot room at double or more of those listening distances.
Klipsch makes some "pro-grade" speakers for these types of applications: http://www.klipsch.com/kpt-jubilee/details
If you want Reference Level in a space as large as you are talking about, you NEED high sensitivity, high power handling capability speakers. The Seatons and JTR's I previously linked fill that bill. The Klipsch Pro Line also fills that bill. JBL and several others will do the same.
Let me say again, you have 10,500
cubic feet of space to fill, and your listening distances are 17, 25 and 33 feet. You are mating all this to a 150" to 200" display. Consumer-grade speakers and receivers need not apply.
