The Park Place Build - Page 2

Very philosophical, HF - I like it.

So by eliminating an unwanted light source, I also do away with a "free" acoustic treatment. I imagine if I sound treatments are done right, the loss of the "trap" can be compensated.

In terms of seating, the distances from my screen wall are going to be 11.5 feet and 16 ft. If I go with a 115" screen and using the 1.5X screen width rule, does that mean the second row has to be my "prime" viewing seat?

I lean towards the more immersive; Mrs P prefers the 2/3 - 3/4 distance. Guess where we end up sitting?

So if I place speakers and use AT for the second row, how much will sound suffer for the first row? Obviously there a lot of variables here - I guess to rephrase...in qualitative terms, how would the average person's listening experience differ while sitting in each row? Would it be bordering on unbearable for an audiophile?

Surely someone must have a multi row theater and has watched a film from a non-prime seat.

okay then...I've read some threads that advise to place the LCR tweeter height between the ears of the 2 rows. I think I'm going to go with this, and if it doesn't work, I only build up the stands or chop them down like that of a lumberjack.

Now if I could pick your brains regarding the HVAC. My room's dimensions are 12' x 21' x 9'. Will a single dead vent to the hallway or utility room provide adequate ventilation for this size of room? I do have a supply and return line overhead but would rather not have to tap into them. Is my only other choice a mini split?

My wife and I are not marathon movie watchers; however, my equipment will be located inside the room. Do I need to address the ventilation for the equipment independently?

Thanks, HF and DE. I'd rather not tap into the main house supply and return so am trying to find alternatives. What about the following:

-2 adequately sized bathroom fans: 1 above the equipment room and 1 behind the projector
-2 dead vents: 1 return and 1 supply

I have the first hvac contractor coming by tonight to give me a quote on a 1 tonne mini split with the outdoor unit off the ground and the indoor part to be on the back wall of the HT. The run would be about 10 feet total.

You bring up a good point, F. I was thinking if I go the route of a mini split, that's all that I would need overlooking the need for a return. What are the consequences of a pressurized room?

Re - heating needs, I would be getting a unit that provides both cold air and heat (down to a certain outside temp ~ -15C).

I meant to thank Ted White and John Hile earlier on in this thread - sorry guys. The service I received from them was top-notch; their prices were competitive with local suppliers even after duty and shipping; and the shipment arrived on time even though I ordered on election day and after Sandy did her damage. I fully understand the sentiments on these boards regarding The Soundproofing Company. Thanks again!

I'm taking delivery of my projector and screen today. Christmas in November! I went with the X30 because the price was right, and I don't care too much for 3D. The screen is an EluneVision 4k AT 110" wide, Scope, 1.15 gain. Interested to see if this screen can compete with its competitors at double the price.

This crossed my mind (even surprising myself!) which had me thinking access panels, but then the soundproofing done on the phone booth would be mitigated; however, if the space outside the theater where the dead vent exhausts (or intakes) is not sound sensitive, couldn't the fan be positioned at the end of the ducting where it would be way more accessible? I'm assuming Ted's manuals show the fan in the middle because it would be smack in the middle of all the absorptive/damping material.

I got a couple of quotes on the supply and install of a mini split heat pump - both were $4000 CAD (that's like a couple of bucks US ) The specs are 12000 btu, 1 zone; the install involves a pipe run of ~ 15-20 ft, drain line about 8-10 ft into my sump pump, outdoor unit off the ground. I'm convinced the margin on these quotes is close to 50% after all costs. But they have bills to pay and mouths to feed like everybody else...errr, I guess.

Thanks, guys!

A few more questions regarding dead vents: I'll be building a screen wall using 2x2s and GOM fabric, and I'm considering placing the supply vent so that it would exhaust into this space. Will the air be adequately pushed through the fabric into the rest of the room? The return vent would be along the back wall of the theater.

Also, being so close to the LCR and subs, will the soundproofing stand a chance?

This is the reason I love this forum! The knowledge and experience of other members is what inspired me to take on this project. Thanks!

Okay so I thought I had everything figured out....dead vent in hallway exhausting just in front of my screen wall + dead vent in utility room at the back of the theater drawing out the warm air...all kiboshed by Mrs P because she thinks the dead vent in the hallway will be ghastly.

Back to the drawing board I go.

I think the answer is soffits. The front and rear would house the supply and return respectively while the sides would be only to match the rest of the room or possibly some can lighting. If I were to go this route, I know I'd have to soundproof the soffits with the ducting, but the sides would not need soundproofing, correct?

What if I wanted to add some cans to the front and rear soffits? Can they coexist with the ducting and insulation?
Would I need to build backer boxes for these cans?
Lastly, should the front soffit be built in front of the screen wall or all the way out from the front wall?

My unopened boxes of GG and clips are staring at me wondering when the heck I'm going to use them lol.

The last sentence I wrote above could not have been more prophetic seeing as it's been over 4 months since I last posted.

I'm dealing with some a couple of water supply lines running underneath my ceiling joists. How important is it that I have these rerouted? I'm going to be using clips + DD + GG.
