Let me catch you all up to speed with my build. I've been stock piling materials for several weeks now and am slowly making progress on the framing.

My first theater design was in 2009 for a new home I had designed (architect by trade), but we didn't build it. Fast forward 3 years, bought a newly constructed home in January of 2012 and put in a couple of provisions for my dedicated theater during the build. My dad builds homes for a living (and built mine), so I got the chance to add some dedicated electrical outlets and coax to the closet under the central stairs which will be my future AV/Media closet.

Pay no attention to the color scheme as I haven't decided on ANY of the colors yet.


Xray view facing the screen:


I'm moving this water pressure tank next weekend so that it's out of the theater:


Framed the entry door:


I'm using 2x4's spaced at 24" on center and will be using one layer of 5/8" drywall for the walls and soffits (more on this later). I'll be using a million and a half tubes of acoustic sealant anywhere I can. I built the wall parallel to the existing stairwell wall and held it off by 1". And also built the return wall which creates the storage space behind the back of the HT. I'll be picking away at the other two walls over the course of this week. I plan on holding the walls along the concrete foundation walls by at least 2" to allow for the water inlet pipe run back to the storage room. I'll be wrapping the new pipe in insulation so that it doesn't create noise within the wall.

The finished room dimensions will be approximately 12'-2" x 19'-8" x 7'-3" before acoustic treatments. I've fully decoupled the walls using the room within a room concept. The only attachment points to the pre-existing structure will be at the sill plate that rests on foam sill sealer and the tops of the walls which will be held utilizing RSIC-DC04's fastening thru the existing drywall into the floor trusses. The existing ceiling is 5/8" drywall with engineered floor trusses with the cavities filled with R19 fiberglass batts. Since I'm building a "fish-tank" I'm hoping I can watch movies and play my video games while my wife and son sleep two stories up. We'll find out since, once I get the first layer of drywall up in the room, I'm going to do some serious, full range, high SPL testing. If I find that my methods are not sufficient I will add another layer of 5/8" drywall with Green Glue between the staggered layers. If that still doesn't function, I'll just have to adjust the maximum volume setting on my Onkyo! :heehee:

I'm new to posting here but have been an avid reader/researcher of both this forum and AVS. So I'm familiar with the methods used for sound isolation and the like. I haven't set a budget on this build as I will pick away at it as funds allow. So far, I've got a stock pile of all the 2x4's I'll need with only the riser and stage lumber to purchase. I've got seven 3" can lights for the soffits, black Lutron dimmers, black outlets, electrical boxes, wiring, 200' of CL2 speaker wire, PVC electrical conduit which will create a raceway around the soffit for future low voltage runs, RG6 subwoofer cable, a 7.1 HDMI wall plate for the AV closet, High Speed HDMI cable for the PJ, all the R13 insulation I'll need for the walls and soffits and probably a bunch more of miscellaneous items I'm currently forgetting.

Every trip I make to Home Dustpan :rofl: from now on, I pick up at least one 50lb bag of sand since I will need 30 of them to fill my stage. I'm currently at 8. It's less burdensome to lug one or two bags down every couple of days rather than trying to do it all at once. BTW, that's over 1500 pounds of sand...

I've got some 3/4" MDF left over from subwoofer builds (I install car audio as a part time job) which I will use to make backer boxes for outlets/lights and such. I'm going to mount my PJ within a hush box which will have an exhaust fan dumping the hot air into the adjacent storage space and keeping as much of the PJ's noise out of the HT.

I'm framing the soffits in such a way that actually makes them more like roof framing. They will not touch the existing ceiling and will hang from the new wall framing at the perimeter of the HT utilizing Simpson Strong-ties. Therefore, it will be decoupled from the rest of the house. Any penetration into the HT drywall will receive a backer box of MDF and sealed with acoustic sealant. The soffit and the main ceiling cavities will be filled with fiberglass batts as well.

I'm going to build an 8' x 8' riser and push it to the back and one side of the HT. This will allow my in-swing door to fully open 90 degrees and will allow for the most seating. My seating plans are to get a reclining sofa for the front row and I'm still battling my decision for the back row. I've found some real theater seats locally on craigslist, but I'm sure they aren't all that comfortable. But at only $150 for two rows of 4, I may just buy them and see if I can squeeze both rows on my riser 8'x8'... Since the theater will be used by only me 60% of the time and by me, my wife and one son 25% more, with only the remaining 15% being for family gatherings and parties, the sofa will be the money seat while the back row(s) are "filler" seating. I may have just talked myself into buying those seats while typing this! :heehee:

Actual shot of one of the seats I might buy:


If you haven't noticed already, I tend to ramble on and type too much but it's mostly due to me keeping a running list of things I need to do or decide on or even things I need help with.

And before I get bombarded with "what are you doing for HVAC" questions, let me give you a bit more information. I live in Maine. My basement is 8 to 10 degrees cooler (even more so in the winter) than the rest of the house and currently has no heat source besides the earth below and surrounding it. I've got 2" of rigid insulation under the slab and 8" thick concrete walls around the perimeter. We, here in Maine, don't have central forced air, ducted HVAC systems because we don't usually have the need for cooling. When and if we do, we use window AC units to cool our homes. The adjacent room to my theater will be a game room / bar area which has two windows that can easily take a window AC unit if the need arises. As for heat, the adjacent room will get one of the infrared Edenpure fake fireplace heaters and that's it, no heat in the theater other than warm bodies and lighting (my equipment will all be within the AV/Media Closet). If I find that the air is too stale in the HT, I will simply open the door and run a small room fan to circulate the air. When it's just me in the theater most of the time I can't imagine it getting uncomfortable over the course of under 3 hours and if it does I'll figure out a way to manage it then. For now, there is absolutely zero plans for any venting or cooling for my HT. My initial plan was to use two dead vent systems, (one for supply and one for exhaust) and although it would be a royal PITA, I've designed the framing to allow for me to add them in if I need them, only needing to cut away the drywall. Go ahead, you can say it now... "We told ya so". Yeah, yeah.

I know it! I was very thankful not to have had the flooring down!

Well it wasn't the ice that initially caused the problem, the pipe had been buried by grass so it wasn't flowing well enough to begin with. Our house was built in 2012 and I never knew where the pipe was nor thought to even ask. Now that I know where it is I can keep an eye on it year round and make sure it's clear.

Water is my biggest concern for when we eventually do the basement. It is dry now, and has been for the 5 years we've been here except for a tiny spot that weeps a minute amount in heavy rain. I'm hoping to spray foam and take care of that but you never know where water could come from.

Thanks Joe. It was actually "fixed" by the builder while we were still under warranty, with that thick, heavy rubber stuff that you drill out and inject. Seemed to do the trick except for a tiny tiny bit that still comes through under heavy rain. Anyway, sorry for the derail, I'll look into some additional sealer. :)

No problem derailing my thread.

Honestly my build has stalled yet again due to my architect registration exams. I'm taking one in two weeks so I'm focused on studying. I'll probably finish hanging drywall soon though and then caulking EVERYWHERE. At least that's what's next on my to-do list.

I bought some plywood to build some shelves in the storage room this past weekend so that I can get stuff up off the floor that isn't in totes. That's priority at this point. And I'd like to use up the rest of my lumber to make more work space which means framing the rest of the basement walls. So much to do, so little time.

I'm tentatively setting my finish date on the HT a year from now so that I'll be ready for Super Bowl XLVIIII (notice the 4 I's?). :D

Took my exam this morning. Its been too cold in the unfinished, unheated basement to work. I've got a few space heaters to help. I plan on working on the room this weekend. Trying to get my mom to watch my kid so I have more time to work. I should be able to finish up hanging the last pieces of drywall and start sealing all the gaps and joints with caulking.

I have gmail and it was in my "Promotions" folder. I don't know when it arrived since I hadn't checked that folder until I got into work. It doesn't alert me to emails received in that folder so I found out about me winning by seeing someone post it in the giveaway thread. I confirmed I am subscribed to the newsletter but didn't know it would get filtered in the promotions folder.

It's funny because last night I thought to myself, "If I won, I wonder if Sonnie pronounced my name correctly when he "said it outloud"." :rofl:

Got the OSB cut for the storage room walls. The battery died on my screwgun so I wasn't able to hang all of them but at least they're cut and in place now. Soon I'll build the shelving units out of the scrap OSB and some 2x4's. Most of our stuff is in plastic totes but the shelves will keep what we don't have in the totes up off the floor and more organized.

Image


Entry door opening is framed out and all the insulation is in. I couldn't decide on what size door to get and had already framed the walls, hence the additional jack studs at the opening to accommodate the smaller door I picked.

Image


These three Lutron dimmer switches that are right inside the entry door will control the room cans in the soffits, the 3 cans over the screen and the riser lights and rope lights within the tray.

Image


I got a couple more sheets of drywall hung and cleaned up a bit too.

Image


Image


X marks the spot! Behind this layer of drywall and the X is plywood blocking for future front height speaker brackets. I put electrical outlet boxes with monoprice in wall speaker wire from the closet to each speaker location. I've got monoprice speaker plates that I'll have to paint black for each of the 7 locations I've got in place. If I decide to go with rear surrounds later on I've prewired for ceiling speakers to be installed in the soffit.

Image


Image


I'm using black Leviton Decora outlets and covers throughout the room.

Image


I ran monoprice's "high quality" CL2 rated RG6 cable for the subwoofer amp connection to the stage along with speaker wire to the LCR locations. I ran an HDMI cable from monoprice, CAT6 and pull string within the conduit that runs from the closet to the PJ's future location. I've got plywood blocking installed along with the wiring and boxes for the side surround speaker locations.

This weekend I plan on putting up more drywall of the pieces I have left to finish up the soffits. I'll need ten more sheets to complete the room. I'll be hanging the ceiling insulation once I get the drywall so that I can do both installations at the same time so that the insulation doesn't sag and rip at the staples. Then its on to caulking EVERYWHERE at all the seams, the top and bottom of the walls and the outlets. Some of the outlets need extension rings, so I'll pick those up this weekend too. And I need to buy a 3" hole saw to cut the holes for the can lights.

I still have to add the blocking within the soffit for the PJ box to hang from. Once I get it in and the drywall done I can start thinking about how I want to get the PJ up there. I might just build a "hushbox" although make it more like a shelf with vertical supports on either side of the PJ and leave the front and back fully open so it can easily transfer air for cooling. Of course I'll take pictures so you'll see what I'm talking about.

Because funds are a bit tight right now, I'm going to have to wait on the rest of the drywall. But I've got enough hung that I can finish up the front of the room and start building the stage. I've got all the lumber I need to construct the stage and the riser, except for the plywood (I do have 3 full sheets of 3/4" T&G for the stage though). I've got a bunch of sand, roofing felt and plastic sheeting for the stage as well. So as soon as I get the front of the room sealed up I can start building it. I bought a roll of carpet pad a while back too.

I've got the ten sheets of drywall, rope lighting, carpet, plywood for the stage and riser and the DIY screen materials left to buy which is not too bad. Oh and one more RF-62 II for my center. It's coming together! :T

Thank you. My wife got a promotion today! I picked up a part time job at Tractor Supply doing assembly work (putting together wheelbarrows and lawn mowers) and running the fork lift. That should help financially to finish up the basement projects and still keep gas in our boat this summer! So we've been getting a lot of great news and a steady stream of good luck recently! It's a welcomed, nice change of pace!!!

I'm not religious at all but I believe in "paying it forward". We got about a foot of snow and freezing rain overnight last night and on my way to plow my grandfathers driveway, I saw a couple shoveling their 50' long driveway by hand! I turned around and offered to do a quick plow through. They said they had someone coming to do it but they were late. So they asked how much I would charge and I said, well I plow for my family, I don't do it for work or anything. I plowed out their driveway real quick. They were clearly late for work and the wife got her young son out of the car to wave to me. As I backed out she yelled, "Happy Valentines Day!"

It's moments like that that humble me and I appreciate the "lucky" moments more. The projector is scheduled to arrive early next week! The wife and I are out for a Valentines Day lunch while the kid is at daycare. We'll be stopping at Home Depot for some stuff and then I'll be working downstairs some more.

I plow for where I work so I take care of my drive as well. I clean out the two neighbors drives it's all shared and they always park in the way! Try to be nice and that's what I get. Congrats on the good luck as of late may it stick, looking forward to the rest of your build and enjoy the projector!

I applied caulking to the studs before hanging the OSB to the storage room side of the wall to keep it from making noise when the HT sounds are cranking.

Got the first level of shelving built. Still need to screw the bottom brace to tie the three legs together and I'll be adding another row 24" above that row for extra storage.

Image


After that's done, I'll be framing out the "lobby" walls and door openings and the knee walls around the family room and then I'll be done with framing.

Has anyone on here used the Lavolta LED strip light kit that PE sells for their step lights at their riser or ceiling light tray?
