Why JMAX? Well, my name is Jeff for starters, but after brainstorming forever with the family about what we'd call it, we ended up going with the bad dad-joke that kept on going. "JMAX - it's a letter better" It just stuck so now everyone refers to it as that.

This has been something I've wanted to do over a decade now, but every time I was about to start something else always got in the way. Half of the speakers I used had just been sitting in my closet the last 5-6 years waiting for this day to come. Now with all the new 4K and Atmos excitement I got the bug again and finally managed to put it all together and make it a reality. (Big difference for me considering I haven't even had as much as 5.1 in over a decade now)

While I never posted here much before, I do give thanks for all the threads I lurked in (and drooled over) for years getting ideas and inspiration for how to go about doing things. So far I'm pretty proud of what I managed to put together and wanted to share the build and final results with other enthusiasts. Hopefully I didn't forget too many important details, but feel free to critique and and offer personal recommendations.

Skip this spoiler if you want to follow the thread for progress, or click to jump right to the final room results.

And now for the instant gratification build pictures! (Netflix bingewatch style)


Here we have the future home of what will be known as the JMAX Theatre. Wish I could still find some pics of what my original movie room looked like when I first bought the house, but that was in a time where big screen rear-projections were the in thing. This room had basically been a vacant storage room for the last decade until I finally pulled the trigger on this project. Only remanence of the old room would be the curtains and theatre purple walls. Let's tear it down!

Here's where we started the basic framing to get a nice and even rectangular room. In one of the pics you can see the room we're building is actually to the right of the front door. My house is a pretty open floor plan with plenty of space, so even though it's located at the front of the house there's still plenty of living areas throughout for everyone to lounge in. Being by the front door also makes convenient for when friends come over for a late movie-night and they don't have to wander through the rest of the house waking the others up. Was a little worried at first about closing this room off because it would kill the flow of having two paths to walk around to the kitchen, but since completion I couldn't have been happier with the results.

Early beginnings of playing around with screen-size possibilities with some painters tape, followed by closing off the back wall and a small fortress of Roxul insulation.

Lots of Roxul in the walls covered up by mass loaded vinyl, in-wall surround and ceiling speaker mounts placed, recessed lighting installed, and thick sound resistant drywall beginning to go up all over.

And now the riser for that theatrical stadium seating feel, and more of the buildout where components will go. (One inside the closet, and the other for the Sanus rack facing into the theatre room) Once that stage went up things started to get really exciting for us.

Built another false wall up front to hold the in-wall speaker boxes, not to mention figured it was a good idea with the wall behind it having plumbing pipes running through it. Things were exciting before, but once the speaker boxes went in it became real. Anticipation was even more unbearable now. Also started work on window covering panels here. Dark on the inside, still looks like a normal house with blinds visible on the outside. Made conditions really dark to work in once we blocked out the sun, but I wouldn't want a theatre room any other way.

Sanus case in place, and crown moulding and sconces up. The 2-way sconces were bought at Home Depot for like $40-$50. Think they were mainly meant for outdoor use, but I liked the look of them for the room and they were far cheaper than other alternatives I was looking at. I just changed the original stock to color changing LED bulbs for the blue effect.

Oh boy oh boy oh boy . . .

Pre/Pro's on the rack, front speakers on the main wall. I really want to rack mount a microwave for popcorn at the bottom of my secondary closet rack, but figured there's some science involved that should tell me that's a real bad idea for my other equipment. (even though that would provide for some extreme concession functionality!)

After weeks of waiting for a carpet restock, it's finally in. Unfortunately for me, while waiting on carpet my contractor took another job so in the meantime I found myself listening to every concert DVD I could find on an uncalibrated system while watching it all on a 19inch TV. (That Eagles DTS soundtrack never gets old)

The main hallway before the theatre is themed with older movie posters I had from my original movie room. Behind the double doors to the left of the first picture is where I store my physical movies, and once facing inside, to the right is where the rest of the hidden closet that was cut off originally from the theatre room is. You can access the back of the Sanus rack in there, but the rack next to it houses my DVD players, power conditioners, and various older components that I never use but for some reason don't get rid of. (yay, mini-disc!)

I prefer it this way because it keeps the pre/pro rack clean and locked up with all the good stuff, while the other rack is hidden in a closet but easy to get to, not to mention having the DVD player accessible right next to the movies is a big plus. Much easier than unlocking a case door every time you want to change out discs.

And this is where I am now. Only thing really left on my list is to upgrade my player to the Oppo, and lastly, install the acoustic panels when they arrive later this month. Maybe add some Dolby Atmos and custom JMAX type signage somewhere among the little nitpicky stuff.

Definitely a fun experience to see it finally come to life. (and you got to see it all progress without all that pesky waiting!) :D

Hope you've enjoyed seeing the build thus far, and look forward to seeing your comments, questions, and critiques. (not to mention a list of what else I still need since we all know it'll never truly be done.) :)

- take care!

Nice build. I am jealous yours is done already, or very close to be completed. I like how all came together.

Can you share the info on the carpet? I like that darker look.

Also, I like the choice you made on the Marantz gear and how all of the gear fit's into the 2 racks. 1 hidden and 1 to control realtime in the room . nicely done.

I too am a huge Roxul fan! that rockwool just works. good choice. How do you like the mass loaded vinyl? I was debating on doing that as well, but haven't done allot of research on it.

The carpet is called "After Midnight" and you can get it anywhere from level I - IV for quality and thickness, so I went with the top IV level. Best, softest carpet I've ever had and could easily sleep on the floor in there.

I also love having the two racks. Was kind of unintentional at first, but being that part of the closet is a somewhat narrow fit, I needed the Sanus/Marantz to be visible to the theatre side but mainly because I needed an easy way to access the back panels of it. If I just put it in the closet without utilizing an opening there would be no way to get around to both sides of it. When I get the panels I plan on hiding it's visibility on the theatre side by putting a panel over it on a door hinge. Should also help with any glare distractions.

The other rack was just an old thing I had laying around forever and when I saw I'd have the space to fit it in nicely next to the the Sanus I went for it. Not as easy to get to the back panels of this one, but there's not exactly much going on to need to. Have the power conditioners on the rack up top and an easy access hole that runs next to the pre/pro to hook things like HDMI cables up. As for functionality it works great for me, and everything there is hooked up via IR that runs to the left side surround speaker for easy control.

As for the Roxul, vinyl, and Soundbreak drywall etc, I've never had experience using anything like that but figured if I was going this far I might as well try to go all out (for my budget). I don't have much to compare it to or know what's exactly doing what, but it does do what I was looking to do. Not soundproof, but it definitely dampens and keeps most of it contained in the room and not spill out too far. Having in-wall bass travels through other walls during big scenes, but sounds more like a nightclub way off in the distance if you're in the room next to it. This room is on a corner side of the lot so I had a lot of free space to be loud to work with originally, but I'm thinking the walls have definitely done their job since I can still crank it while the rest of the house is asleep, not to mention no angry neighbors.

JMAX is lookin' good :cool: I know that strip lighting can be 'cliché', but I love it! I love the blue scheme, which flanks my 'Red scheme' in my theater. But I have to ask, are those front In-walls your only front soundstage? I love the hidden-speaker-approach, but I've never really liked in-walls for a dedicated system. Anyhoo, check out my theater in my sig, it will give you a few ideas, or just look for fun. What size screen are you going with?

Yea, definitely cliché but I still love it. Easy way to make it look good without breaking the bank. Guess I should've taken more pics with different lighting, but all the lights can also change colors if I wanted to re-theme it. I'm just partial to the Tron-like blue feel so I leave it there most of the time.

Yea, that's it for my soundstage. Those are the speakers I had been sitting on in my closet for 5+ years, long before I decided I was gonna go all out on this project. Really didn't even look too hard into newer speakers when I started this, but figured since most of my expenses was going to be in construction that I'd just use what I already had. It's my first real experience with an in-wall system but I'm happy with it. They're loud and come in nice and clear. I really just wanted the clean look all over, but also figured if I used big speakers hidden behind the screen I'd lose too much more space coming out with the wall.

This was my screen:
Seymour AT screen with Premier Frame = 2.39:1 ratio
(Frame dimensions: 136.7" x 61" , Image Size: 130" x 54.3")

Cool, I'll check yours out!
