My screen is actually fixed frame acoustically transparent and also DIY using Seymour XD material.That room looks incredible! I remember the "before" pic you posted of the damaged ceiling. Wow what a comeback. I esp like the acoustical treatments. I have never seen ceiling treatment like that. What is it called or who is the mfg'er?
I know most everyone has the more practical flat panel direct radiating video but I much prefer a projector like you. My screen is good quality DIY but fixed. Looks like yours is a roll down. May I ask what brand?
The ceiling treatments are a mix of Auralex T’fusor and Geofusers all stuffed with Ultratouch denim insulation.
I prefer front projection also so I can use 3 identical speakers for LCR and not compromise with the center channel. Also I can have a 150” 2.35 screen and change aspect ration on the fly which is awesome!
