Richard Green room tune?

Herman, thank you for your input!

As you stated, the journey can be more fun than the destination. I have read up on the subject extensively, and Jon Risch's website was the most informative, as it normally is, regarding the DIY Room Tunes. He goes into full detail as to what you are conveying, and it does make a lot of sense. His plans produce these designs with differing characteristics on each side of the device, making them more "tuneable" than either company offers.

In the end, if this route is the correct one to address my issues, I am confident I can achieve the same type of results as either company.

The energy IS the problem. Especially when you have brightness sticking an icepick in your brain when someone hits a high note. If that's the case, which it is for me, nothing else matters. I've been listening to headphones. Redirecting energy would be good, but the cost or complexity of a project to build or buy diffusors to cover a large room would be rediculous. Too much bsorbtion makes the music dark and not worth listening to either. Room tunes (both brands) use the same technique as a lot of others. absorb, but have reflective a reflective serfice that will keep the high freq bouncing around. Will it help with brightness I don't know.

"Even though I'm sure they will be better than nothing, given the fact that manufacturers go through many prototypes with a wide variety of materials to finalize their designs it seems unlikely you will hit upon the most effective combination of materials and dimensions on your first try."

Some do - some don't. Obviously, if you see fiberglass or wool and a reflective surface, they didn't put a lot of R&D into it. That's all most acoustic treatment is. And given the price, I would assume they know that we know.

How to raise the volumetric efficiency of your sound room? This is the question we need to ponder and to ask ourselves and engage and to resolve. Knee jerk reation is to tame to kill..Sounds like alot of other bad shit happening.Thats another physical issue. Anyway its pressure its air..its compressed it expands what other mechanical or fluid sciences can be drawn into this so as much energy can be maintained, retained, maximised not always reduced, but redirected. Just a thought or a few. Tom

Robm, you are correct that these products are not based on rocket science. They are not inventing new substances with magical acoustical properties. Rather it is fundamental principles applied well in an attractive package including convenient mounting brackets at a reasonable price. They are designed for those who don't have the time, skills, confidence, and/or resources to go DIY. I built my own amp but I would rather pay for these products. Working with fiberglass is something I want no part of.

Trelja, I looked around at Jon Risch's stuff and don't see where he covers the same ground as these corner treatments. Of course the discussion on the absorption properties of the different materials applies, but his stuff is either designed to trap bass frequencies or (in direct contradiction to the Eighth Nerve philosophy) to put absorption at reflection points.

Let us know how your's work out. Pictures would be nice.
