So the Sound Proofing Company has several SPC wall solutions. I was looking at the SPC Wall solution 1, very close to what i was going to be doing, however, it looks like it's marketed and tested with 24" OC studs

Why can i not find anything related to 16" OC stud locations, basically standard building code spec? I am pretty sure I'm not going to reframe to 24" OC. :eek:

So is there a link to some test results or reall world experience with 1/2" gypsum, 2x4 - 16" OC wood studs, Roxul Safe and Sound, 5/8" gypsum, GG, 5/8" gypsum. tape, texture and paint ?

Continuing the research, I came across Roxul's Safe and Sound spec sheet, but i just realized they provided some STC test results with 16 O.C. wood studs.

Roxul Safe and Sound Specs

The wall profiles i was planning are this, but not sure i will even achieve STC 50 without doing some type of decoupling.

Wall Profiles - Left, Right, Back Walls.
2x4 wood stud 16 O.C., ROXUL SAFE'n'SOUND, 4 mil poly vapor barrier, 5/8" gypsum, Green Glue, 5/8" gypsum, tape, texture, paint, 1" Linaccoustic RC, GOM Anchorage Onyx.

Wall Profile - Screen Wall / Front Wall

Plan A
2x4 wood stud 16 O.C., ROXUL SAFE'n'SOUND, 4 mil poly vapor barrier, 5/8" gypsum, Green Glue, 5/8" gypsum, tape, texture, paint, 1" Linaccoustic RC, 3M-77 spray adhesive, 1" Linaccoustic RC, GOM Anchorage Onyx.

Plan B
Minimal Screen wall, based on BigMouthinDC design.
All the wall behind the screen and on the sides would be 2x4 wood stud 16 O.C., ROXUL SAFE'n'SOUND, 4 mil poly vapor barrier, 5/8" gypsum, Green Glue, 5/8" gypsum, tape, texture, paint, 1" Linaccoustic RC, 3M-77 spray adhesive, 1" Linaccoustic RC. Not sure what i would cover it with.

So, the real question is, should i be expected to get reasonable results with these profiles?

Other than installing hat channel, are there any other recommendations you could provide?

I don't think 16" oc will cost to much in the way of sound transmittal. My guess is they go 24" to wring out every last bit of sound proofing. When I do my framing it will most likely be 16" oc unless someone can provide rock solid evidence 24" is significantly better.

My plans are real green so don't laugh or make fun of me. I'm still trying to figure it all out. And I've just started working on my plans in detail. Like you, I have a builder. Mine's a Semi-Custom Builder so we've asked for a lot of things. But it too gets expensive and they were in such a hurry to lock us in we let them push us around and hurry us. Now I'm kicking myself because I really never got a chance to break it all down and study it. By the time I got all of my plans and such from them they tell us we're locked in to what we've already submitted any additions or changes now will cost $250 just to submit a change order, $500 if plans have to change and we have to pay 100% of the cost of the difference in the change. So I'm trying to collect everything that I want and hold on to it until the last. Or decide if I can do it myself. I'm going to be doing a lot of that myself.
I'll have to do it one weekend and have you and the wife up to spend the weekend and we'll work all day and hot tub it and party into the night and I'll smoke you some food that'll make even Smokey Mo cry with envy. Lol.
I am a week away from my construction meeting..Still have changes coming into my head daily right now..Nerve racking..lol

Based on your plans that were attached, a couple of things i would change on your build.

  • the location of the entrance to the media room,
    • depending on which way you are planning to have the screen wall, IMHO, I would want the screen wall on the outside wall on the right. I would have them put a single 30, 32" or 36" solid core door entering the media room next to the 'Stor' location. The 'Stor' location could be used to have an inwall 19" 42u rack. get rid of the slant wall that the plan has the door in, and square that off.
    • if you put the screen wall on the wall that is adjacent to the 'Game Room', IMHO, i would then move the door on the left wall, straight in front of what looks like a overlook balcony to below. you could still use the 'Stor' space as a location for a AV rack. again, make the room 4 sides only, get rid of the slanted wall. I would have them put a single 30, 32" or 36" solid core door.
Do you have a build thread started yet? plans of layout for the media room?

Have not done the construction meeting yet. Solid core door was definitely on the list. I thought of closing the storage space off instead of the door and have the wall opened into the theater to use as a bar and equipment holder area.
You are correct to assume the screen would be on that outside wall. I kind of like the angled door because if it is opened during a movie the light wouldn't hit the screen if the hinge side was on the right and door opened in...
I thought I would have them double dry wall the entire room and I would green glue in between the the layers as they put it up. Also double the floor too.
Any other changes you can think of?

Hi James, I am very familiar with Wildwood at Northpointe. We spent many weekends looking at homes there and thought that's where we would end up, it's a great community. We ended up buying in Cypress last year and then we unfortunately got flooded during the tax day flood. We just moved back in a couple of weeks ago after nearly 7 months. The good news is we made many upgrades during the process even though the house was brand new. The best upgrade was building out my theater. It's smaller than your room (approx 11'10"x 16 after wall treatments) but I was able to get 2 rows with a riser and an 110" screen. It's cozy but very comfortable.

I just wanted to let you know I bought my theater seats from the popular place outside of San Antonio that you mentioned. They have a great showroom but as an FYI they may not have what you want in stock. It seems like they keep most things in their California warehouse but not in Tx. I went with the Seatcraft Sonoma and it is a great seat of very high quality. The buying experience was very good and I highly recommend them. As you probably know, they are the owner of Seatcraft and 4seating.com which has received some poor reviews so I wanted to let you know that my experience was a good one. If I can answer any questions for you just let me know.

Gypsum and Green Glue walls

So the Sound Proofing ......So is there a link to some test results or reall world experience with 1/2" gypsum, 2x4 - 16" OC wood studs, Roxul Safe and Sound, 5/8" gypsum, GG, 5/8" gypsum. tape, texture and paint ?
Like you I've been looking a lot for facts about which is better 16" o.c. or 24" o.c. builds. But unlike you, i might can change to whichever is better. Through what I have been able to find it appears that 24" o.c. is better. But along the way I did find a lot of helpful info. And some examples of 16" & 24" o.c. cases. So check these locations out. If someone with more intelligence can teach what all of this means it would be helpful. But I do hope these two locations will help. Attached also is something I put together. I was going to call each and ask them various questions to see if they could determine my STC rating for the design I was wanting.

https://www.soundisolationcompany.com/wp-content/uploads/images/pdf/green-glue-diagrams.pdf
https://www.soundisolationcompany.com/solutions-products/soundproofing-walls/green-glue-2/

You mentioned Roxul Safe and Sound gypsum: is that better than say any of the other quiet rock out there? I think SoundBreak was another one. Is there a comparison of each out there anyone has found as to which drywall is the absolute best?

Time for an update...finally.
It's been awhile since I've been able to sit down and focus on the thread, with finalizing the move from Alaska and let alone having to renovate the rental property in Wasilla in December (brr....) and to put it on the market, and finally enjoying Christmas and the new year.

I've done some additional planning and sketching on plain ol' paper (Sketchup coming soon). With all the great builds out here, I have gone back and reviewed my initial design several times and have made changes to incorporate some of these great build ideas into the Re-Deux. I hope i can build as nice as half of these out here, such as the "Better Late Than Never" build by @jhermsmeyer or Cranky's Cavern by @crankycowboy and of course the outstanding acoustic treatment work done by @VETDRMS in "The Learning Curve".

All of these builds are truly inspirational, and I hope I can even come close to replicating the success that they have had in those.

Below are some of the changes, quite honestly, based on the above mentioned builds.

Screen Wall - Inspired by the final outcome of the builds mentioned, and the discussion by @[email protected] in here, I like the size/sound staging that will be achieved with a short throw room that Re-Deux is, along with the seating locations for 2 rows, without feeling like sitting in the front row at the local theater. Using what @BIGmouthinDC posted, this is what I hope to mimic, with some changes to the sofit/marquee.



Sofit
- Trying to replicate what @hifiaudio2 did in his previous build, and his inspiration from the Cinemar build, i hope this works out.



Acoustic Treatments - When it comes time, i hope to mimic @VETDRMS acoustic treatments inspired by @audiovideoholic on the ceiling and around the room.



Wish me luck, as I am ramping up into full swing.

This is my favorite build too - the L/R outside the screen frame providing an accurate replay platform.

It's not a matter of my preference, it is simply this array will replay film with the extended width required as outlined in my post in the dedicated build forum. (Very uplifting to learn you have considered the evidence and Big's build example!)

And you can test it for yourself.

Try these scenes to confirm discrete effects linked to offstage character location (these are not mentioned in the original thread) with encoded effects to sync to them outside the screen frame:

Sanctum - the early scenes in the cave. Several characters are heard in L/R channels but not seen.

Despicable Me..when Gru sits on the alligator couch...

These are just two interesting scenes confirming the front speaker array is there to provide a window on the universe of the characters – but it extends past the edge of the screen frame.

Wish I could experience your system when it's done! Good luck!

Sirjaymz!! Looks like you have done your homework, and have a great plan laid out. Thanks for the mention! If I was able to inspire you in some small way with my build, then I'm honored. I look forward to seeing your progress!

Made a some progress over the past couple days.

Cleared out the game room next to the HT to allow for overflow of materials and parts. That was a chore. I think i need to adopt a new rule on if I don't use something within 2 years, no need to look inside, just donate the box... lol

Removed the sconces and listed on craigslist.
Removed the ceiling fan and sold it on craigslist this afternoon :D
Removed the carpet and all the pad. loaded it into wifes car. she's like , REALLY!? I haven't bought my replacement vehicle yet since i turned in the Passat to VW for Buy-back.. so we are down to 1 car. :mad: but, we got paid handsomely for driving a car for 2.5 years for free and they paid more than i bought it for. can't go wrong there.

Took up the first of two 3/4" sub-floor boards to access the cavities to add Roxul Safe and Sound and caulks all the crevices. It was screwed and glued, so you can imagine the effort needed. :eek: Only 1 more to go.. ugh.

Maid's coming tomorrow, so gotta clean up the mess so she can wipe down.

looks like a great plan!

do you plan to maintain access to the attic hatch?

the acoustic treatments reference looks interesting. as I am still fiddling with those, I will take a look.

good luck!

Yeah.. so there is about 6 feet from the front of the existing wall to where i am going to build a new pony wall that will support the roof. that will move the entire wall back about 3 feet, and also provide significant room for the 2 subs and center channel behind the screen.
I will be installing that same door in the new pony wall.
Then i plan on building a screen wall similar to yours and @crankycowboy 's wall. i like how you enclosed the speakers outside the screen.
i'm limited on overall width of the room, as i still want my L/R channels to be at the 30 degree mark left and right. If i need to move the MLP forward to achieve that, i will, as it will also provide addtional leg room for the riser seats, and allow me to move those forward off the back wall. @Tedd recommends about 4 feet, but, not sure that I will get that. depends on where i am able to make the screen wall at in relation to having enough space for the Klipsch RF-82II's to be toed in at the 30 degree mark as well.

Thanks for the luck. I definitely can use all i can get ;)

hey, wanted to thank you for the learning curve thread reference!

I have been reading through the massive treatments thread trying to figure out if I am on the right track (which is not very efficient)...

the learning curve thread seems like a good summary, and shows some qrd diffusor builds, which have always fascinated me. I might be a bit to far along for wall placement, but sounds like they might be useful on the ceiling too.

thanks again!

No problem on referencing the build thread. @audiovideoholic provided some really good knowledge to #VETDRMS for his build, and I personally really like how it turned out. the build quality is very good, but also, having the support of somebody that has the know-how is always a huge plus for the guidance that is provided.

I read through some of the treatment thread as well, and you are right, it's so difficult to get that concise build design qualities that probably all rooms should have, but difficult to ascertain what those are with so many responses. It's good that we all talk about it, but there really isn't a consolidated thread that summarizes the knowledge base that I think you and I have been looking for. 'The Learning Curve' thread pulls some of those key elements out and provides a good consolidated items for us to quickly review. Needless to say, the build quality is outstanding, so it makes it easy to follow along.

I'm glad to see the "Better Late Than Never" build is pretty much completed for you. You are in full measurement mode, and looks like you have some decent results. I am not completely sure on what measurement software you use or the method, but I am completely fascinated by how far we all go through once we get these build put together. It's the technical side of me that loves the 'tweaking' part of this whole process, let alone the kicking back and watching a movie once it's all done. Man, I cannot wait.

I would not use linacoustic at the bottom of the soffit, you want a nice open path into the fluffy insulation for maximum bass trapping. Just use chicken wire to hold things in place above the fabric.
