Nice review Todd.

Very Nice!

Here is a picture of diffusion placed in the ceiling first reflection point. This is Hill Top Recording Studio in Nashville, The diffuser is 8 ft by 2 ft by 14.5 inches deep. The effect on the room was profound. A bass standing wave was eliminated, the stereo image improved, and John, the...

Do you have a picture of your rear wall? I would really like to see that.

Wow, what a bummer. I used to attend CES and loved the high end audio section. Where I live I have fiber optic run to the house with blazing fast internet but the tv is topping out at 1280 by 720p. I do have an Oppo blue ray player, and blue ray discs look awfully good to me. I have one of...

Don't forget SLS Loudspeakers. They pioneered ribbons in professional PA systems and had a great line of 8" two way studio monitors.

I am giving it a whirl, will update soon......

Well, here is a picture of a bare diffuser that is similar to my best design. I can supply the bare product at a very attractive price. It would be difficult for you to duplicate, because the material I use is made to my specifications (high density) and is not sold on the open market...

"The Arqen diffuser is no gimmick. The designer not only thoroughly modeled the design but built and tested them for his PhD dissertation project. It's been thoroughly peer reviewed. He isn't the inventor of the stepped diffuser, that was developes by one of the Principles at RPG and also built...

Amen to that! I have made lots of diffusers using Shroeder's equations, and while I don't have the measurements that some people insist on having, I do have empirical evidence that trained ears provide. In every case, the larger (higher prime) deeper (lower target frequency) sounded better...

Now those are a gimmick!

I was talking about these: I just found this, and I find it an interesting design. What do you think? http://www.xix-acoustics.com/2011/09/04/why-does-the-acoustic-ramp™-work-better/ #1Negatron, May 21, 2017 Last edited: May 21, 2017

I like the Revox reel to reel! I used to be a Revox dealer, the reason they cost more is all the audio is discrete, the metal parts are all galvanized (they wanted to have them last, even in the jungle) and they copped Willi Studer's motor concept, the stator was attached to the housing, and...

Here is a couple of them on the back wall of this media room. It is a very high performance diffuser that I will put up against any competitor. It is a hot dog of a diffuser!

Oh yeah, $400.00 for their Dirac enabled box is an unbelievable bargain! It is worth it just for the eq's and crossovers!
