I won't have to paint the speakers again, however I do have to polish the finish once the paint sets up properly. I also have to pick up the legs for the right and left. I decided to go with the same speaker legs that come on the Yamaha Soavo 1PN. I can order them from the Yamaha parts site and with new spikes they'll get the speakers up high enough for the ports to work their magic. I don't have enough money to order them right away, but I do plan on getting them ordered sometime this month. I also am waiting on some new surround sound speakers to arrive, I'll post updates when I get a chance to give them a go.

Materials for risers
Uploaded Dec 17, 2009 03:44:13
Starting work on the risers for the front speakers. You might be wondering why risers over traditional speaker stands. The big reason is because risers help isolate the speakers from the vertical room modes better then stands will. This isn't really an issue for smaller speakers, but for ones that can hit lower hrz it can be a nice upgrade.
Uploaded Dec 17, 2009 03:44:16

Finished with the risers

To get the tweeter even with my ear level I needed to raise the speakers about 15-16 inches. The risers get them about 13 inches higher and once my feet for the speakers arrive I'll have them up another 3" (need bottom port clearance). I know they don't look amazing, but I've always operated under the principle that ascetics come secondary to acoustics. I can tell you they make a big difference, not subtle in your mind changes. After finishing the first riser we tested it out, and it was like all the sound was coming from one side of the room. You could hear faint noises from the other speaker but the difference in volume and bass celerity made it even hard to hear the other speaker. I've said this before, but I have to mention it again. Positioning is one of the single most important things you can do with your speakers. Even if you do nothing else, make sure you position your speakers correctly. Right now my front left and right form an equilateral triangle from the center listening position & the tweeters are lined up 3" short of my ears (will be dead on shortly). P.S. The second subwoofer (Rythmik F15) is still in the process of being saved for, holidays are putting a strain on my budget so it's been slow going.

I broke out the SPL meter and checked the levels. Took a little while to tune them to match the fronts. Tuned them both ~6db less then the front speakers then the sum would bring them up ~6db.

I spent the better part of the night they arrived in a trance listening to all sorts of instrumental music from around the world. It really made a huge difference in the room. The bass is more uniform and encompassing. It doesn't feel like all the bass is coming from a single side of the room anymore. In the future I do plan on refinishing both of the subwoofers to match my fronts. That however will be well down the line.
Time to get to work!

You should be able to make them any dimension. My risers are about 20"^3. You obviously need 6 sides, and 1 larger piece of the top. A single sheet of 3/4th MDF at your local home depot will build 1 the size of my riser with plenty of left over. Have the people at home depot cut the MDF down into manageable sizes, make sure to leave buffer because they aren't always the most accurate cuts.
Cutting down to size.

Start by cutting the 6 pieces of MDF that will make up the cube to the right size and angle. Most table saws have a 45 degree angle option.
Uploaded Mar 26, 2010 21:17:59
You want to cut the area to open up the area below the woofer. With 4 of the 6 sides of the cube, cut a square out of the center. When doing this it is a good idea to raise the saw all the way up.

Gluing everything together
Uploaded Mar 26, 2010 21:18:03
I used a pin nailer to hold everything in place after it was glued and clamped, but if you don't have one you can just use wood glue and clamps. A 90 degree clamp is very useful here, just make sure you get one that is deep enough to clamp on to the 45 degree edges.

Before and after riser

This is with 1 sub, 0 digital correction (so no EQ's or PEQ's), crossover @80hz & the position of the sub is about the same (I eyeballed it). The dip at 65 is likely the vertical node, and the overall DB increase is because I brushed the gain knob lifting that sucker onto the riser. Blue is before, red is after.

Uploaded Apr 02, 2010 08:27:54
With the risers in place and the position of the subs settled I can finally begin applying a little digital correction. I still have lots of plans for room treatment in the near future, but for now I'll digitally correct what I can and benchmark the results. This will will have to wait a few more days tho, as I have a new preamp coming in soon.
Uploaded Apr 08, 2010 04:42:49
The new receiver arrived. I have experience with Integra pre-amps so the setup is identical short of a few minor differences. I was considering picking up some external amplifiers to use, but after giving it a shot I decided to stay with the internal amps until I finish building my replacement front speakers later this year. Until then I think my money is better spent on acoustical treatments and a better quality power conditioner. The calibration is finished for now. There is still a lot of storage in the room below 35hz, it decays down about 30db within the first couple hundred MS, then stagnates. My goal this summer is to design and build several LF dampening systems that'll increase the decay <120hz with out overly impacting the mids and highs. The designs for them are still in the trial stages, so until then my next DIY project will be simple dampening panels for the mains, but I'm considering a twist to the traditional design. I haven't decided if I plan to execute it tho, it would require a lot of space I don't have.
The build on the new diffusion & absorption array for behind the main listening position.
Uploaded Aug 31, 2010 15:31:27
I wanted to add some diffusers to the room, but from my experience they place an unwanted emphasis on the mids and highs. I decided to correct for this by using several smaller diffusers and alternate them with dampening. I wanted a fairly low target frequency for the diffusers, but I would be unable to achieve that with the given period width. I've corrected for this by placing the other diffusers within ½ a cycle of the highest frequency that was cutoff due to period width. To prevent repetition effects I used alternate functional permutations for each of the 4 diffusers by varying the primitive root value. The listening position will be too close to be completely effective, but I'm building it anyways knowing that most of the acoustic treatments I build will carry over to my next theater, which will be large enough to accommodate it. I tested a few models using specular reflections and it seemed to produce intended results, and consulted a few acoustical engineers I decided to press forward.
Now on to the build process: I started with the frame.

The Wood Dye
Uploaded Aug 31, 2010 00:04:16
I didn't have enough of my usual wood stain to finish this project so I decided to try something new. Instead if just using a wood stain, I'd use a dye, and apply a stain over top. I tested it on a sample that I liked and decided to give it a go.
Uploaded Aug 31, 2010 00:04:17
This is after the wood stain was applied, I was happy with the result.
The Clear Coat
Uploaded Aug 31, 2010 00:17:55
The clear coat is finished. I'm thinking about how I want to finish the diffusers, but I don't know what color would look best. I'm gonna hold off until I can see the near finished product in the room before I decide how to finish the diffusers.
Applying the fabric
Uploaded Aug 31, 2010 00:17:57
I don't like the look of dampeners that just coat the fabric over the top of the wood. It takes a lot more work to make it look nice attaching the fabric on the inside, but the end result is much better in my opinion.
Applying the fabric
Uploaded Aug 31, 2010 00:17:58
To keep the fabric taught I cut some thin strips of balsa wood to keep the tension on. It's rigid enough to keep the fabric in place and very easy to work with. It's soft enough that any normal staple gun should go through and it doesn't shatter when stapled.

Mounted it from the ceiling and placed it about the width of the dampeners from the wall to increase the effective range of the absorption.
Uploaded Aug 31, 2010 00:18:05
Unfortunately I ran into a hiccup with the mounting, the diffuser is ~3 inches off center. I'll have to adjust the mounts and the cable length to correct this, but that'll be for another day. Tonight I'm gonna take a break and watch a movie.

Uploaded Sep 11, 2010 02:24:54
I used the same products and process as the diffuser, so I thought I'd spare the details. If you have any question about how to achieve this finish I'm more than willing to help answer some questions. Because they are just panels I'm tossing up on the walls I didn't to a ton of sanding, with a lot more effort you can make the finish look much better.
Uploaded Sep 11, 2010 02:24:56
Same as before, just using thin cuts of balsa wood and a staple gun to secure the fabric. Takes more effort but I prefer the results to fabric wrapped around the frame.
Uploaded Sep 11, 2010 02:24:57
Just like the last ones I fill them with insualtion, OC703, 705 or Rockwool. I personally use a lower density fiberglass to get a little better LF absorption from sympathetic resonance at the cost of mid and high end absorption.

Ignore the window, I'm doing some work on it. I'm in the middle of building a huge bass trap, twice as thick and much larger that'll be suspended from the ceiling above the subwoofers. It should be done in a few days. After that I'll be building some membrane resonators for the corners. I'm planing to have both of those projects finished before the end of this month!

The start of the bass trap that will be mounted in the area above the subs.

I'm getting better at getting the fabric to turn out nice. I've had a lot of practice by now, lol.

A comparison with my other puny panels. Twice as thick, and much larger all around.

He's keeping watch over the subs to make sure they don't get out of line. Now on to the corner membrane resonator! I'm still in the design phase, I have a good idea of how I want to build it but I'll need more supplies and some I can't get locally.
