I bought a second projector Planar PD7130 and am making a small HT room for the wife and I. The room is real small 11'-5 1/2" wide, 13'-4" deep with 8' ceiling. The room used to be an exercise room right off of our master bedroom. The floor has the black foam rubber floor tile. I painted the walls and ceiling flat black. I installed black sound panels and bass traps across the front and gray sound panels and bass traps on all the other walls.

I got a good deal on some RBH WM30's and made brackets so that I could mount them in front of the panels and traps. The sub is an old NHT 10" ported that I already had and I am using an A35 HD DVD player for DVD's. The screen is a 106" fixed frame. I was surprised at how good the on-wall RBH speakers sound when mounted in front of the panels. I took a couple of pictures. One is of the front right corner and the other is of the screen. Please excuse the spots. They are from the camera. My wife could not find where she stuck our camera and I used my daughter's underwater camera.

The Planar produces a very nice image using DVD or HD DVD. For BD I use my other system.

Added:
I am now using three small sealed subs (NHT 116 drivers) and a pro crossover to convert the three front speakers to a 3-way design. This allows me to cross to the on-wall speakers at 100Hz. I run the front three channels full range + LFE. I use the small sealed subs have an F3 of 31Hz and I run them up to 150Hz. I have also added a 6.3CF ported sub (Shiva-X) in one back corner and a 2.0CF sealed sub (2-10" drivers) in the other back corner. Now this room sounds better and has more impact than my downstairs room that uses RBH Signature speakers all around.

I finally got around to taking some pictures of the back wall and a picture showing how I mounted the RBH WM-30 in front of the 2-3/4" thick sound panels. The corner bass trap is 4" thick. This small room does not have near the quality equipment (audio or video) of my bigger room, but it has better acoustics. I have been doing most all of my movie watching in this room now. Picture taken with the lights on full.

Last picture is with lights off, but open doorway. http://i243.photobucket.com/albums/f...o/P1010172.jpg
I made all of the sound panels using beveled wood frames, 2" and 4" Roxul and acoustic fabric that I bought from Fabricmate. Projector is mounted on a shelf about six feet above the floor. I wrapped the shelf with molding, but the room is so dark you can't hardly see the shelf.

Nice looking panels. Reminds me of a screening room in there. Looks like you have acomplished yourself a cozy setup.

Thanks Steve. The panels make a huge difference. I am glad that I came up with the idea of mounting the on-wall speakers in front of the panels. I am really pleased with the image and sound in this room. It sounds fantastic. The Planar throws a wonderful image.

I like the image that the Planar PD7130 throws, but I wish the throw on my Marantz VP-12S4 would work in this room. The 12S4 has blanking, which means when I am showing movies in 2.35 I can blank out (make black) the top and bottom bars on the screen. In other words built in masking. It is a great feature. The 12S4 has three memories so I have one set for top and bottom bars a second set for side bars and a third for letterbox. The 12S4 can only throw a 92" image in my small room and I did not want to go that small.

Lookings like a great setup. Are the wall panels accoustic treatments?

Yes. Small rooms are more of a sound challenge than big rooms. 2-3/4" sound absorption on the walls and 4" thick panels for the corner bass traps.

Thought that I would update this thread. I am now running five subwoofers. Three sealed up front and a large ported and sealed in the back. I have also moved the center speaker behind the screen and installed a Center Stage XD screen. This room provides a great cinema experience. [IMG][/IMG] I do have grills on the subs, but you can see the Aluminum drivers in the picture because of the flash. To see more pictures, click on the link labeled "Upstairs Dedicated Room"

System update. I have been running three Klipsch RB-35 speakers up front and two RBH WM-30 surround speakers.

Right front

I now have a mechanical masking system on the screen. You can see the bottom masking panel in the pictures. Picking up three JTR T8 speakers for the front stage Wednesday. I will get pictures once I get them in place.

Reworked my front wall to install the JTR T8 center. Here is a picture with the masking screen removed.
[IMG][/IMG]
Blocking shown is what spaces the screen out from the wall. The shaft mounted in two pillow block bearings is what keeps the masking system level and so that the panels move together. The shiny black is wet paint.

Front stage all in place and everything calibrated. Picture turned out dark so I overexposed it. So glad that I got the three JTR T8's for the front stage.

I guess I skipped a few changes, but I will bring this thread up to present. My screen is now 107" wide (viewing) 2.40 aspect curved AT screen with EN4K. Using a JVC RS45 with a Prismasonic HD6000F lens. A Lumagen Mini 3D for vertical stretch for the lens. A Darbee for added sharpness and contrast. Speakers are now DIY using AE Speakers TD12M's, SEOS-12 waveguide and the DNA-360 CD. For subs, I am now running three sealed 18's up front ( two SI 18's and one Mael-X) and two sealed 12's ( TC Sounds) in the back corners. Now for the pictures.

DIY speakers, three up front behind the curved screen:


Front three subs:

Very nice! Are you sure you have enough bass? (Jk). I imagine it sounds amazing in there.

The bass is great. With the PEQ I get lots of very low bass 10hz and less. So strong that at first I was scared for the drivers, thinking they must be working very hard, even though by the math, I should not be able to exceed xmax. Then I would re-play a scene with the lights on so that I could see the drivers and they were hardly moving. Not sure that I was even using half the xmax and this was at reference level.

The JTR's are very good HT speakers and not bad for music. At reference level, they were not as smooth and clean as the DIY. I had both set up in my room for a week and a half. For HT, they are close, but the DIY edges them out as you get closer to reference level. For music the DIY pull ahead at any volume level. When listening to movies at reference level with the JTR's they sounded loud and you knew that you were listening at a very loud level. When listening to the DIY speakers at reference level, it does not seem like it is playing at reference level. It is so clean that you feel like you can turn them up louder.

I forgot to show a picture of the back lighting that I installed. It does not show off the speakers behind the screen, like I was hoping. You can see the mains a little bit, but not real clear. The mains are heavily toed in since these are controlled directivity speakers. Mains are crossed in front of the seating.

Lighting does not look purple in real life. I have the lighting programmed into my Harmony.

Here is a little bit better picture of the front stage area:

Looks great, Mike. Hoping I can enjoy my room a bit before catching the strand of upgraditis that seems to be going around your neck of the woods. wink.gif

FYI-I'm really enjoying the RS45 I ordered from you. Very happy with the image quality even though it hasn't been calibrated yet.

Here are some measurements. Subs only, no smoothing, with Audyssey. Dynamic EQ is on.


Right speaker with subs, Audyssey and 5db of boost down low.

Those DIY speakers look great Mike. I really like the JTR's and I even picked them in a recent blind speaker GTG so I would love to hear them sometime.

One of my friends here in town who is MrSmithers on avs is doing a similar project with SEOS stuff so hopefully I will get to hear them soon. Very tempted to start a project of my own but lots of research to do before I get there.

Now lets see that "beautiful view of a lake"!!!!!!!!!!!!!!!!!!

Hi AVS5,

Did you use Bwaslo's crossover by chance? I see a familiar dip in your mains response. Its very similar to one Beastaudio was seeing with the AE woofer on a SEOS12/DNA360. 3-5db dip right at crossover.

If thats actual and not measurement artifact id think it would be "fixable" with a tweak in crossover. Bwaslo might know right away what to do by looking at the seperate driver measurements and the combined reaponse idk. Might be worth picking his brain though?

Its not bad at all and your sub reaponse is impressively flat without EQ.

I have five subs. Three 18's spread across the front and a couple 12's in the back, which help even out the response.

Been thinking about the crossover and what I could do.

What are you using/considering for speaker management for your 5 subs? I am planning a similar setup with 2 15" subs up front, and 3 10" balancing subs around the room.

Options I am looking at:
1. Behringer DCX2496
2. MiniDSP 2 x 8
3. Xilica XP-3060
4. QSC BASIS 922az

What are your thoughts on these choices?

You need to swap the polarity on your tweeter or woofer.
