Allen, that's not up. That's down.

Very good price. You definitely had higher prices in mind when we negotiated for the 6' x 4' unit that I got. Now that the price point has been established, do I get a special discount (this time

) if I order 2 2' x 4' units for the early reflection points on the sides?

We are hearing similar comments from a top recording engineer here in Nashville that has been mixing in the control room we treated at Streeterville Music. He is the engineer for the Nashville Symphony recordings and numerous other projects. He says the same sort of things as you, but adds that he can mix comfortably for a much longer period and the the mixes hold up when he plays them at other places. The studio musicians also like to be in this control room.

I spend a lot of time in my project studio as well, over the years adding more and more diffusion and trapping. It makes a huge difference in your ability to tolerate long sessions without listener fatigue and more importantly the ability to focus and evaluate over long periods of time.

Almost everyone that I know as a recording engineer has noticed that as the session goes on in duration, so does monitoring level. By the end of the session, you usually end up monitoring very loudly just in an effort to hear anything. With proper room treatment, it seems that you don't go reaching to turn up the level at all, and when you walk out of the session you don't feel like you've been pummelled for hours.

I am really liking the sound of my room right now. Now I understand what it means to have more air -- each note has more definition and coherence but lingers just a little more to give that phatness to the music. The whole reverberant harmonics (that you can only hear when interfering standing waves get chopped down) make music come alive like it's real.

Yep!

Cheers

That's a great point, and it's absolutely true. When you can hear clearly you don't need to crank the volume. And when you do crank the volume, it's much less fatiguing than without acoustic treatment.

As I was listening to a pair of TL speakers driven by a SET amp vs. a T-amp this weekend, I noticed an interesting difference that correlates with use of diffusors. The sweetness, phatness, liquidity, airy or whatever else that people use to describe SET sound is very similar to the effect that good diffusion adds to a room. Adding diffusion to a room is like using a SET amp without losing any dynamics. The notes becomes plump and juicy -- visualize Marilyn Monroe and loose Twiggy if you will. In modern parlance that would be Diane Lane vs. Calista Flockhart.

I am sure this is a more natural decaying pattern similar to that of a live music in a good acoustic environment. Thanks Ethan (Real Traps)and Allen (SRL Audio) for bring diffusion products that are priced within the spending realm of an average audio consumer. Comparable products (no foam stuff) at RPG are priced almost twice as much. My room absolutely benefits from having diffusion. Obviously, every room is different and the milage may differ but I firmly believe that diffusion (after bass trapping is done) will help most rooms. In fact, I think I will get more for the early reflection points on side walls.

Wow! Pretty competitive. Do you have any good photos?

Hi all, we are in the process of completely updating our website....however you can find photos of our diffusion and absorption modules under the acoustics section......project gallery. These are all studio control rooms we have treated, however woodsyi and others have installed them in dedicated listening rooms (in our view the same thing as a control room, minus the old school mixing console),,,send any questions our way!

Rob and others, our website has been revamped. Please check it out and we look forward to hearing from you soon...

Hi Woodsyi....
I was wondering if you had done the comparisons yet, The new diffusors should be in your possession now, and I am sure everyone would like to know the result of your testing......

woodsyi · « **Reply #29 on:** 22 Mar 2007, 07:30 pm »

Here they are.

I initially wanted 2'x4' but George thought it would be better at 3' wide if I could swing it. After carefull measurement, I thought I could so George made a model with 3' width for me.

Of course when I received them, they were too big to fit. I had to do a whole lot of rearranging but I got them up at the early reflection points on the side walls. Both are 3' wide, 4' height and 9" deep.

Left wall

Right wall

Rear wall

I also put up more bass and high frequency absorbers in the front.

I am done for a while with the room as far as acoustics go. I frankly have no more place on which I can hang anything. Considering I even stuffed spaces above the ceiling tiles, I can't do more. I am sure my wife is thrilled to hear that I am done.

I like my room. You ever hear the garage commercial where a wife calls for a missing husband because he doesn't come out of a souped up garage with fridge, TV and everything else? Well it's like that. I am making all kinds of excuses to go down there and stay there. I think I will be volunteering to do laundry soon.

The side diffuser panels definitely make music more delicious. They don't make the big difference that the rear diffuser makes but the subtle differences are noticeable and appreciated. I recently went to listen to the Irish tenors at Strathmore which has gorgeous acoustics.

I also heard the same trio at Filene Center at Wolftrap which is an outdoor arena.

My room sounds more like Strathmore than Filene Center -- more controlled re-verb that makes it sound like you are right in front of the singer. Filene Center has more flat sound.

Hi Woodsyi, and everybody else.....

We have been adding photos and models with architectural trim options to the website. We have also signed on Guitar Center to address the pro market. We are looking for good stereo/home theater dealers across the country. Any references to them would be appreciated!

Do you have any data regarding the frequency range of diffusion for these? I realize this is probably just plugging into a formula, but I don't know what kind of diffusors you're using or what the depths are.

woodsyi · « **Reply #32 on:** 12 Jun 2007, 06:17 pm »

Bob,

I think they are set up for 1k Hz if I remember correctly. The depth on my units go to 8.75". They work great in my room.

ctviggen · « **Reply #33 on:** 12 Jun 2007, 06:36 pm »

Thanks. I think it'd be nice to get the massive ones for behind the listening area. Sadly, all of my money right now is going toward a baby crib, infant carriers, blinds for the baby's room, etc. But, maybe one day I'll have the funds for some diffusion. What I really lack in my room is diffusion. I think I have enough broadband absorption, so I'd like to try some diffusion.

Would a crib make a nice diffusor?

Sure it would diffuse you from ever having SEX again.

I had to make a comment on this...I just put a set of diffusors in the rear of my listening room (had a few 2'x2' squares lying around, so I stacked three of them on the wall about 6' directly behind my listening chair), replacing a GIK 246 panel I had there before. Am REALLY impressed as to how much improvement this made to the sound I'm getting from my system. This was in addition to the full complement of Eighth Nerve Adapt products I've got in my room.

Can't believe I didn't do this long ago...

Daygloworange · « **Reply #37 on:** 22 Jun 2007, 03:56 pm »

Which diffusors are you using Phil?

Cheers

PhilNYC · « **Reply #38 on:** 22 Jun 2007, 04:09 pm »

They are actually RPG Abfusors. They were designed for absorption, but act as "nearfield diffusors"...

Diffusion on the back wall really works. Put up a bigger one back there Phil.
