Moving along. Installed poly batting and did initial setup of plazma TV, motorized pj screen, front speakers, projector...
The 110" diagonal 16:9 Da-Lite Cosmopolitan screen is hanging from two 8" L-brackets at either end, approx 6" from the front wall and bottom is 27" from floor. It was a bit of a b*tch to install the heavy screen by myself and with only 1/8" clearance to the walls on either end of the motor casing. For the motor wire routing, Da-Lite only provides holes on the end of the cap, so I drilled an exit out the back in order to hide and route the wiring as I had no clearance on the side. I find it really strange that Da-Lite would only include an ugly side exit for wiring... who would ever want to look at that?! Another oddity, Da-Lite provides a white wall switch (installed to the right by the door) for the default motor setup. Who would ever want a white wall switch in a projector room? I'll be spray painting that switch and some other items with matte black. For now, it matches the white poly batting. LOL.
The side Mythos 10 speakers are positioned just in front of the screen to allow clearance for the bottom bar on the motorized screen, and toed in (right speaker to left seat, left speaker to right seat). The center channel Mythos 10 front is flush with the screen face and angled up at maybe 20 degrees. I fashioned some L-brackets to hang the speakers from the walls and achieve the desired angles simply by hammering the brackets to the bend needed.
Initially I had intended to mount the side speakers with the tweeter (center) up at screen mid-point (56" from floor), but that seemed way higher than optimal for seated position (and the mid TV height of 48") so compromised with a tweeter height of 50". Aesthetically, the speaker bottoms align with the top of the wainscoting trim you see on the side walls.
The front height GemXL speakers are mounted using two Adam Hall SPSG3B Wall Mounts
. These are metal brackets are the most solid I have seen... far better than any plastic mount. Minor caveat is to discard the flimsy "safety cable" as it is useless. I bought 4 of these items for less than $15/ea and was astonished to receive 4 pairs (8 total) for under $60. Great deal! Current price is $26.50 at Amazon so perhaps I scored a better than normal price
Here is the Sony HW30
mounted at screen center and minimum height allowable above the rear window. Lens center at 89.5" from the floor nets 5" above screen top which is at 84.5". Lens center is 18" from the 9ft high T&G ceiling. Throw distance from lens to screen is 12' 3".
$40 AV shelf is from Peerless
. Sure I could build a basic shelf with brackets for $10-15, but that would need to be 20 inches wide which is much bulkier than this minimalistic looking Peerless shelf which almost looks like the projector is hanging in mid air. Laying on top of the HW30 is a black microfiber cloth I use to drop down over the pj lens when it's not in use, instead of messing with the lens cover and misaligning focus, etc.
Due to the wood ceiling and window headers in the rear wall I decided not to get too cute with the projector wiring. I'll run the power, hdmi and ethernet along the wall corners to the AV stack where my power center/conditioner resides.TBD:
- Currently waiting for a shipment of black 16oz Commando cloth from ScenicSource
to complete the fabric treatment in the screen/tv alcove.
- Install AV console/cabinet in rear alcove and connect wiring.
- Add window treatments (aka curtains). Have legacy curtains on hand, wife needed new sewing machine (of course) to complete her hemming task.
- Mount the same type of curtain on a swing arm or track for the glass pane entrance door. I would have done this even if we had installed a solid panel door as the finish sheen needed to be subdued regardless and black paint was not a WAF option.
- Add some furnature (toss in a legacy couch and hope the WAF promotes getting new seating
- Mock up surround and rear speaker (all GemXL) locations before fishing wire through walls. Need to decide if rear surrounds are in or out and adjust surround locations accordingly. Likely the main seating will be close to the back wall so rear speakers may not be optimal (per discussions in Audyssey threads). Have enough speakers and amp channels to do either 7.1 or 9.1 setup.
- Find optimal location along front wall for the SVS sub, likely somewhere between 2ft from either side wall.
- Tidy up wiring.
