I recently moved into a new house and the family room is now laid out as pictured. It's a moderate sized room (about 20'x15'x9'), with many entrances/exits. The entrance on the top left is actually a door that can open/shut, which forces my front left speaker (and consequently the whole system) to the right. The other openings have no doors. The bottom (back) of the room has a large 3 panel sliding glass door. On the upper right is a raised hearth that extends from the opening to the front wall - with a brick veneer from hearth to ceiling. This may make mounting a speaker on that side of the room difficult, but I'm convinced I can drill into the mortar.
The primary seating position(s) are the double reclining couch on the right side of the room, which are relatively centered. I realize this seating layout is suboptimal for HT, but it's the best I can do in here with so many entrance/exits. You may notice the absence of my sub in this layout - since it doesn't fit well into this room, I'm moving it to my basement rec room HT, and planning on picking up a (much smaller) Epik Empire for this room. Note that I plan to move my 602s downstairs as well, since they're a bit large to use as surround/rears in this room (and definitely not wall mountable - which is a must)
The problem: You can see how I've got my surrounds currently situated, but there are a couple issues with this: 1. if I move the left speaker to the rear (bottom) of the room like the right rear, I can't generally hear them since they're below the couch, and 2. it's far too loud and direct for the person in the arm chair where it's currently situated. These speakers are also way too big to wall mount, which I'd like to do to clean up the room.
The proposed solution: since this room is used 90% of the time for HT use, switch to bi/dipoles for the side surrounds, and pick up a pair for the rears as well. While I'm upgrading, switch to a 7.1 setup since I now have locations that work as such. You can see the proposed locations for the bi/dipole speakers in the drawing as the triangles in red.
1. Would I be better served in this situation by using front high speakers rather than rears? I can easily accommodate them, but I think they may look more like a "wall of speakers" and a bit less room friendly. I'm still not sure how much I would gain out of adding rears over a regular 5.1 setup.
2. Since there is limited space to the outside of the rear speakers (to the sides of the sliding door), would I be better off with monopoles there? I'm concerned that half of the bi/dipole sound field would be thrown directly into the side walls since the speaker will likely be within 2' of them.
3. Should I mount the rear speakers at about the 4-6' height, or near the ceiling angled down (in the case of monopoles)? I'm planning on having an electrician come in and wire the rear of the room for those speakers, and I'd like to put the panels right under the speaker locations if I can, so i'd like to get it right on the first try. I'm leaning towards positioning them around 5-6' high, not near the (9') ceiling.
4. Due to the brick supports on the large mantle over the fireplace on the right side of the room, the surround speaker on the right will have to be just in front of the seating position, so it would be impossible to put the listener directly in the "null" of a dipole. Is this ok? Or should I go with bipoles if that's the case? How would this affect a quadpole like the Axiom QS8s?
5. Would appreciate suggestions for speakers. I'm pretty set on some form of indirect speaker for the surrounds on account of seating positions, but I'm open to suggestions for the rears. Whatever it is needs to be wall mounted though - I want to get these speakers where they can be heard and not have to take up my floor space. Budget is ~$1000 for all four. On my short list right now are Axiom QS8s surrounds paired with M3 on-wall rears, or infinity ES250 surrounds and rears (if I can find them used).
