Built-in Projector Shelf - Can It Be Done?
SandS replied to Caine77's topic in Room Acoustics, Construction and Design
I'm a 'go big' sort of guy, gone up a few sizes over the years, now running a 130" scope from Ozts. I had one P j sitting in a 'pidgin hole' in the ceiling, the front of the room has a raised ceiling so the PJ was over the lower part of the ceiling. Worked ok, had a vent into the roof. Has your room got the same ceiling hight as the garage I take it you would box it in to the room. As long as you have enough room around the PJ for air it should be ok -
Cabinet design for LCR & subs
SandS replied to Johnny_Boy's topic in Room Acoustics, Construction and Design
I used to have a SubM and Mark Seaton said you needed to be about 4" out from Wall (100mm) I was going to buy one more for under my AT screen but ended up building two 15" folded horns I would have them side on, but that's only me. The guy I sold the submersive to has 2 now and I'm sure he has them side ways with not much room. Less bending down if AVR is up higher. -

If you just had the Emotiva's on the bottom would you have enough room for the AVR etc either side of the centre speaker. maybe then you would have enough room for both subs side ways. -
Converting front room to theatre
SandS replied to jazzman1974's topic in Room Acoustics, Construction and Design
Looks very nice. I have a 130" AT scope with 2 rows at 3.5 and 5 metres. Would love a 150" . I sit in the front. Although I have Seaton Cats I was very impressed with the Krix mx5 with only 2 Atmos it was a great sound. I like the idea of the baffle wall setup. The mx5 did not as much base as my two 15" folded horns but the mx10's have 12" , bigger than the mx5 I listened to. I think you can extend the baffle wall each side of the center with filler plates to widen the left and right a bit. With a big room area, is a third sub needed some where in the room. Krix from Aussie must be a -
I wouldn't do it but seen where people don't run a centre, just a phantom centre. When one of my Catalyst amps was being repaired I just had L and R. It wasn't too bad...

I was at a 4K PJ demo a while back, 150" 16:9. The centre speaker could have been a bit higher but it was nearly on the floor. As soon as there was speaking in the movie my eyes where drawn down to the sender speaker. I supose I am used to a AT screen now.

130" . 16:9 starts to get very high, how high is the ceiling? I have 130" scope AT screen and the 16:9 image is close to the floor before I zoom back out. It would put your centre speaker very low if not an AT screen Is an AT screen an option for you My 300mm riser is 3.6m back from the screen and 1.5m deep. I sit in the front row. The 3m wide image on a 130" 21:9 screen is about the same as a 135" 16:9.
