Welcome to Scott's home theater and addition build. Thanks for the great info from the AVS guys, it was definitely a learning experience and still is a work in progress!


Updates are on page 3, here is a recent pic of the 2.35 acoustically transparent screenwall in progress

Square rooms (19x19) are bad for audio. Many here would extend the wall where that room inside your room is to make it more like 19x14

From time to time, the Gene Pool could use a little chlorine ...

See, that is true, but there are so many theaters that are in square shaped...
What if the room has very good acoustic dampning? (Is that the correct term?)

Hmmmmm What to write?

Thanks for the link! Any other suggestions/comments on layout? I'm going to the depot today to pick up more wood for the riser, and finish up the wiring this weekend.

Well, is there a way for you to show us actual pics of the room? That way we'd know what's been done and what's there to do. That'd help a lot and make it easier for us.

Made some progress over the weekend, since its just me at the house now

Mid atlantic 24U rack rails and a couple shelves. Thoughts on using the right side for a DVD rack or just insulate over it?



Back of the rack, took a long time to clean up the wiring


Spent some cash on Blue Jeans Cables (3 series 1 HDMIs & a component). I still have room in the conduit for more wires, also lots of mounting points for the projector in case it needs to be moved.



Here is the screen wall and the insulation is finally done in the theater room. Still need to finish up the rest of the addition in order to get the insulation inspection.



Mounted the Klipsch ceiling speakers & enclousures in the master bath. These are wired into the closet too.

Lots of beer at the time of purchase, and multiple video inputs. I already have 13 speakers a couple subs running to the closet, so might as well add in some more HDMIs.

Yeah, I was thinking the same thing. Scawt, doesn't your AVR have HDMI switching?

Nope, it's an older Yamaha THX that doesn't have HDMI. I'll upgrade later, so shouldn't be a problem

Last update for the addition and HT room until the drywall is done:

I officially hate insulation now. I'm never doing this again by myself. The walls were fine, but ~15ft vaulted ceilings in the master bedroom weren't fun.



looking the other direction


So the plumber hooked up the tub and it was leaking from the jet lines. I'm glad the spa company replaced the part/labor under warranty, but still have to put the POS back in the hole


Built the final two inwall speaker boxes for the theater room. I'm glad those are finally done. The windows will have hinged cover eventually.


Picked up the last two surround speakers


I've never been so happy to have two buckets of glue


I should have put the putty pads on before the insulation, but didn't think about it till later. I'm glad their in before drywall though.


I had my electrician friend come back and wire in two dedicated 20A for the a/v closet. The 15A is the outlet below. I feel a lot better now



I'm waiting for some more rack shelves to come in and faceplates from stayonline. Custom PS3, XBOX, etc..

Wait until you try to hang the drywall on those ceilings. I ended up solving that little issue with the ol' checkbook. Goes against all my DIY street cred, but my lower back is more important.

Good advice. I think I'm going to do the same thing, I don't want to deal with the drywall on a project this big. I had my drywall/sanding/mudding experience with the kitchen remodel already

If you are planning on putting a door (such as glass) on your equipment rack, I would recommend setting the rails back at LEAST 3 inches to allow for knobs, buttons, and other protrusions from the equipment.

My rack is set back about 2.5" and its BARELY adequate for my glass door.... it's good enough that I don't want to dismantle the whole thing to move it back .5-1"... but annoying enough that I wish I had..

If I'm not mistaken that is actually one dedicated 20A hooked up to four outlets. You would need two runs of the yellow romex for two dedicated 20A. Don't worry you should be fine.

However you do have a code violation of using a 20 amp receptacles on the 15 amp circuits. I also spotted one next to the bucket of GG. I suspect you bought them for every outlet?

A few locations are now also expecting the ground plug to be on the up side for new construction.


Theater looks like it is coming along great.

I noticed that too, 20amp outlets on 15amp circuits is a no-no.

Yep, our house is one of those. Ground plug up, thankfully we found out (from a neighbor who also built his own home) about that before I wired them in - otherwise I'd be redoing the entire home.


Looking forward to more pics! BTW, I'd second the $$$ on the drywall - going high and vaulted, etc... not too much fun. I don't think it will hit the cred too much. ;-)

Thanks for the heads up guys! I'm going to give him crap about the outlets, so they will get fixed before final inspection.

I'm pretty sure the two 20A are on a single 12/3, so I guess they are not dedicated.

Dedicated means that the line comes from your breaker box directly to the outlet box with nothing else connected that consumes power or more importantly for HT that introduces some interference or ground loop issues into the system.

Your two duplex outlets (4) connected to the yellow Romex are probably dedicated.

Aww, I thought they had to be separate runs for each outlet to be dedicated, but yes he ran it directly to the box. Thanks for the info!

If the run is 12/3, then it can be wired as two dedicated 20A by sharing the ground and neutral. In the breaker box the black to one breaker, red to another breaker, white to neutral, and bare or green to equipment ground. Caution if you use half size or tandem breakers, be sure to plug the black and red onto opposite legs of the panel.

I also think it's a good idea to use a 2 pole breaker for a shared neutral circuit. The down side is when one breaker trips, it trips the other as well.

I love the green stuff


I can't wait till I can paint and cover the windows. I'm going to Lowes tomorrow to pick up some black and a dark red for the theater room. I'll test out of some other colors too.


Guest bedroom:


Going upstairs:


Master bedroom, bath and closet :






I should be able to finish the flooring next week for the hallway and guest bedroom. I'm going to pay for the carpeting since I don't want to do that again.

I still can't decide whether to do the AT screen, but I'm definitely leaning towards it after all of the threads that I read. I need to start sketching some ideas out.

Thanks! I'm trying to figure out what to do with the 4 zones and the volume control. I ran speaker wire and extra Cat5e to zone 2 and 3 from the rack, but 4 got neglected and is outside without the Cat5e. I want a single receiver to control everything, but 7.2 plus 3 other zones is getting complicated

I'd be curious how you achieve that. In my own build (7.2 for HT and 2ch for ceiling speakers in the playroom), my installer had me pick up a separate 2ch receiver, aside from the Marantz AVR8003 driving the dedicated theater. I had just assumed that the ceiling speakers could share the Marantz with the HT.
