  1. Square rooms are almost certain to have dreadful bass nulls - avoid like the plague. Only thing worse is a cube. You can model room sizes here - try putting in a 3m x 3m x 3m cube. Ideally your room will model all dark green - in reality you'll probably have problems at a few specific bass notes. Fyrchek plaster is usually a bit cheaper than the Soundchek and performs at least as well. You'll need a lot more soundproofing than just that to get the level of reduced noise transmission you described. Next bang for buck is to add insulation to internal walls (heavy fibreglass or 48Kg/m3 polyester). Next step is yellowtongue flooring under the plaster. After that you get to more expensive stuff like isolation clips and furring channel. A single solid core door with a jamb at the bottom is a good start. Also consider adding a return air vent so you don't suffocate in your sealed room.

    The Oppo is a great choice!

    I'd suggest listening to a demo before spending that sort of $ on a sound bar.

    For your LCR speakers it's best to get a matching set as mismatched speakers can produce odd sound changes in panning scenes. If you're going 7.1 rather than Atmos you could go with in-ceiling speakers, but it may take a while to get used to the soundstage coming solely from overhead, especially so for the front soundstage where your mind expects it to come from the direction of the screen. For the LCR speakers consider going for an acoustically transparent screen and installing in-wall speakers behind the screen. Note, AT material will have a lower gain (reflectivity) and you may want to step down another 5"-10" in screen size. Did I mention that when planning this stuff you soon realise how much of it is about compromise...

    Cheap speaker cloth : where to buy

    Not red, but some options here and here.

    I originally went with a scope screen because I had a setup where I needed to fit L&R speakers under the screen. If starting from scratch not sure I'd still bother. A 140" scope screen gives a 16:9 image of ~110", so a big difference. A 140" 16:9 screen gives a scope image of ~133", so a much smaller mismatch.

    If you don't have a slide to move the lens out of the way, the image would be stretched out to fill the scope screen if your projector doesn't have a "squeeze" mode to bring it back to 16:9. Not ideal to leave the lens in the light path and use image processing to squeeze it back to the correct aspect ratio, but if you don't have a slide, that's what you're stuck with.

    TBH I wouldn't recommend going down the path of an A-lens nowadays, not since lens memory and higher lumens have become readily available. If you really want to go down the rabbit hole, there's a good used one here for $2.2K (sold for $5K on a group buy). Best matched up with a motorised slide, but not essential. An A-lens stretches the image horizontally and your projector then chops off the black bars and stretches it vertically to fill a scope screen.

    No matter which way you go you'll end up with black bars on some material - 16:9 stuff on a scope screen has them on both sides. If you go with a scope screen projector placement becomes critical, as you'll zoom between two image sizes (unless using an A-lens). Not sure how far you're sitting from the screen, but 150" is very large. To get enough brightness for HDR on UHD you'll probably be replacing lamps before their nominal end of life (lamps dim as they age). Depending on how far back you sit and personal preferences, I'd be wary of going over 140", regardless of aspect ratio. I'm running a 130" scope majestic screen (with an A-lens) and sitting ~3.7m from the screen. Projector is an older X500, so no HDR.

    The standard domestic installation is 4 Atmos ceiling speakers.

    To be honest, none of the power amps Selby sell offer a whole lot of bang for buck IMO. A used Elektra would be the best bang for buck - older models prior to the HD/HD2 go for ~$1400 for a 7 channel, lower for the 6 channel versions.
  12. OK, that would be close!

    OK, looks like in-walls could be problematic in that space.

    You might also consider in-wall speakers for the surrounds, but would recommend you check with a stud detector whether you have any issues before committing to this path. I couldn't go in-wall as the cavity for a sliding door got in the way. I went with a set of Dynamix that have a single mounting point at the rear.
