Looking forward to seeing the finished product
Speaker cable? You only started building a month ago!
Sure, but I still can't believe it. I've been working on mine for an eternity, so I'm quite enviousHelps when you're not doing the heavy lifting yourself.
Yeah I looked at that extractor too. It should do the job. I think the passive inlet will be fine. It'll be negative pressure though.I've finally made a decision about air recirculation/extraction for the cinema.
Extract
I've ordered a very quiet 5" inline fan. SL TD350SILENT
Really hope it fits as it is pretty large. Intend to run 5" ducting from above the AV cab to the front via the pelmet and across the front pelmet to outside.
Inlet
Currently planning to take 5" inlet from the kitchen. No fan, going to try it with just the positive pressure caused by the extract. Run ducting to behind the projector hush box and push air from back of projector to front.
Good plan.I’ve spoke to an installer and they can run the pipes outside so don’t need to decide now.
Must say the build quality in these Hisense TVs leaves a lot to be desired.
Need to finalise locations for Atmos speakers, now all the joists are in. I've marked what I think - all to scale. Brown shows the joist locations and the steel running across the room. I've labelled MLP, Atmos locations and pelmet. TopFronts will be inceiling, TopRears in the pelmet - both approx 45 deg.
LCR (Red) shown for context.
Due to the pelmet and joist spacing they will be just inside the Left and Right. Any thoughts?
I can go wider but they are then very close to the sides of the pelmet so figured reflections would be more of an issue. @mb3195 @kbarnes70 ?

I have back to back communicating doors for my room-in-a-room build but don't bother closing the outer door most of the time. With other doors closed in the house and a long sound path back to other occupied rooms there is next to no sound travel of anything much above 100hz.Acknowledged weak areas
- The door will be the biggest weak point. I've considered back to back communicating doors but didn't want the faff. Bolting two firedoors doors together or adding mass to the back. I'm going to see how a single door performs and there from there.
