Dual subs should be a must in a theater of this quality. If you don't want to do dual subs up front, then you could get a couple of in-wall subs from Velodyne, Atlantic Technology, or Klipsch and hide them in a couple of columns on the side or in the rear. I know M&K's subs are expensive but you can get 2 Velodyne in-wall subs with their amplifier for under $2000 I believe. If you do actually decide to go with a multiple sub setup, you will never believe how you went without 2 subs to begin with.

Hi Guys,

I was able to get rid of some older components to help justify the purchase of an HSU VTF-15H sub. It arrives this Friday!

I didn't want to do a DIY sub right out of the gates. I wanted to have at least one decent sub so I could get a feel for what it should sound like. That way if I do end up building my own, I won't be left wondering if it could sound better.
I'm also curious how it compares to the M&K MX350. I'm hoping it blows it out of the water.

I haven't done much research, but when I quickly looked at the DIY kits from Rythmik Audio, it didn't seem like it was a huge saving compared to just buying the HSU VTF-15H.

Congratulations Mario,

Your's is certainly one of if not the best looking Home Theater I have seen on these boards. Good to see you are moving to getting the sound right. As beautiful as your room is, when the lights are out, that the big immersive picture and audio system are what really counts. cool.gif

You bet.

I ordered the following items yesterday from Parts-Express and plan to use REW to help dial in the room.

1 242-743 JAMSTANDS JS-MCTB200 TRIPOD MIC STAND W/TELESCOPING BOOM
1 248-574 BEHRINGER XENYX 502 MIXER 5-INPUT 2-BUS
12 260-770 PENN-ELCOM F1686 RUBBER CABINET FOOT 1.57" DIA. X 0.61" H
1 390-801 DAYTON AUDIO EMM-6 ELECTRET MEASUREMENT MICROPHONE
1 241-348 DAYTON AUDIO CMX-25K XLR MICROPHONE CABLE 25 FT. BLACK

I'm planning on building a 3/4" thick platform the size of the HSU sub and putting the Rubber Cabinet feet underneath it. Then set the HSU sub on top of the platform to help decouple it. This will also make it easier to get in/out of my front cabinet.

Very impressive jl43, and I would definitely second the request for a dedicated build thread - or built thread maybe would be more appropriate - to see more and get some info on your setup.

Here's a couple pics. As I've shown in this thread, I elevated my led strip by about 1.25" to get higher than the black lights (which I still need to install 7 more).
I put the lights closer to the wall so they would have a better chance of clearing the height of the black lights which are sitting in the crown cavitiy itself.
IMG_0890_small.jpg
IMG_0898_small.jpg
I left a gap in my led board elevators so I could squeeze the cables for the blacklights through and not have to go over the led's which would create a shadow on the ceiling.
In the corners, I also made a swooping loop so that they wouldn't be dark. You loop it around and then come back under.
IMG_0899_small.jpg
I have plenty of room to add another led row if I want too. But the effect is pretty amazing when you look up from the center of the room and you can't see any corners. It really looks like it goes on forever.

Mario - Have you had any issues with your LED lighting since the initial install? I am looking to do the same thing and wondered if having four strands of lights on one power source is acceptable. If not, did you add another power adapter along with another ir controller?

Excellent!
I hope you are willing/able to share your progress on this project. It seems like this is the next frontier here in this subforum, and it's thorny and complicated. If you can bring half the attention to detail to this process that you did for the main part of the build, you will get great results, I'm sure.

I thought I mention this in the thread, but I had to use two separate power supplies in the soffit to get equal brightness. Both runs are equal distance. Using one power supply that comes with it won't be enough. I'm guessing you could get a beefier power supply or amplifier that may solve the problem. But I found the lights got dimmer as you add the third strand toward the end.

So how did you hook in a second power supply then? You are still only using one ir controller right? Or are you running two completely separate systems?

That's right. They essentially two independent IR controlled systems. Not that it's desirable, but I can have half the soffit one color and the other half another color.

I have both LED power sources plugged into a single Insteon applicance module. This allows me to press a keypad button at the entrance to turn them both on/off together using the last selected color. I can also do it with my IR remote. Eventually it'll go into MainLobby's user interface too from the iPad.

I haven't done too much with changing the colors so it hasn't been a big deal.

Great, great theater and one I use as inspiration.

I was wondering on your riser, I like the look of hte wood trim around the edge instead of pulling over the carpet from the floor. Do you have any details on its constructions?

Thanks LexMan.

Yes. There's quite a bit of detail in this thread. It starts on this page:
http://www.avsforum.com/t/1208912/the-cinemar-home-theater-construction-thread/1080#post_21402720

And continues on many pages after that during the various construction phases.

Were you able to eliminate the furnace noise?

I have similar layout & design, and am worried about furnace noise coming through the wall. I have one mechanical room that got the full DD + GG treatment on both sides of the wall, but my other mechanical room with 2 furnaces and an ERV has open stud bays and exposed insulation. Like yours, it's pretty busy.. mine also has gas lines & sewer pump and would be hard to effectively drywall because of all the various lines running in/out of the room.

I haven't noticed it since it hasn't been running given the weather lately. But I just turned on the air and you can hear it. It's somewhat of a low rumble and you'd probably only notice it if the room was really quiet.

If you have the chance and the drywallers are there, I'd recommend adding at least one layer of drywall and ideally two. Just so you don't have to wonder. smile.gif

I'm finally getting around to posting some pictures of the HSU VTF-15H sub that arrived. I had a chance to unbox it this past weekend. They really pack that thing well.
As of now, it's sitting in the cubby next to my patch panel (not shown in any of these pictures). I wanted to get some room measurements there before I place it in the front corner cabinet. It's so large I'll probably need some help getting it in the cabinet. I'm hoping the results will be better in the front cabinet since that's the ideal location.

I did do a test fit in the back corner of the room. When designing the room I made sure that this particular sub would fit in the corner and made sure to accomodate for the base board moulding and chair rail depth. It fits snugly in there...but again, I could see small kids getting their hands on it and/or bumping into it.

I also built two custom subdude stands for two subs. I moved my M&K MX-350 into the right corner and onto one of these stands. I used some left-over 3/4" MDF and some rubber feet I bought from Parts-Express.

Looks good, you'll also want to do testing with the various settings and plugs. In my current configuration I have one plug in. With the size of your room you may want both plugs out.

One of the things I like about the 15H is the ability to fine tune it between ported an "mostly" sealed. I'm also running a Klipsch sealed sub in my back corner.

That puppie is heavy, I wouldn't try putting it into a cabinet by yourself.

Mario-

Not sure if I commented previously but you really did a fantastic job with your theater. I thought you mentioned in your build that you had very little if any woodworking experience prior to this project. You would make one hell of a carpenter.

Yeah. There's a lot of config options with that sub. On top of that, throw in the position of the sub and all the Onkyo/Audyssey settings, it makes it difficult to determine the best settings
But it's good to have options.

That thing is heavy. But more so, just really large. WHich makes it challenging to lift by yourself. I'm really thankful to have the walkout basement. It allowed me to get it into the basement myself using a dolly. The double sliding basement doors also make it easy to muscle in large items too.

I'm anxiuos to hear how it sounds against the front wall.

Thanks Dave. Great compliment coming from you.

I really enjoyed learning all the wood working skills along the way. Hopfully I'll be able to continue to put them to use around the house now.

I haven't posted many pics of my MA Slim 5 Rack. I've actually moved things around slightly to allow for better air flow. I had my three Russound CAV/CAM's all stacked on top of each other. I left a little space in between them and now they are breathing nicely.

I definitely need to clean things up a bit in the second rack and will once I nail everything down.

I like having the racks on wheels. It allows me to get behind them fairly easy. However, with two racks and cables that go between the two, you have to ensure you leave enough slack to roll them in/out.

A bit off topic. I took on a small project this weekend using some scrap material left over from the theater.

I've been wanting to convert my shuffleboard table into a buffet table. We'd been using the back bar area but it just wasn't enough room when we entertain for things like the Superbowl and have a lot of dishes.

Initially I was going to build a complete cover using some type or wood or mdf and then wrap it with some type of vinyl. Research found that the vinyl wouldn't be a good idea for hot dishes. So my Dad gave me the idea to use two 6' plastic tables which we already had.

So I built these supports to fit snuggly inside the table.
IMG_1901_small.jpg

IMG_1902_small.jpg

Then I stapled some grippy tool box liners all around the supports to keep them from scratching the shuffleboard table and to keep the plastic tables in place.
IMG_1903_small.jpg



I'll now be able to fit two tables perfectly on top of the shuffleboard table. I'll add a table cloth to dress it up.
IMG_1904_small.jpg


The folding tables are about a 3/4" shorter than the shuffleboard table width, so I'm going to add a 3/4" stop on the wall side of the supports so it makes it easier for me to just set the tables on top and align them perfectly each time. I thought someone else with a shuffleboard may want to do the same.
