Richard Green room tune?

Well, I hope the Michael Green Room Tunes are effective.

As things stand, I have been fighting the same brightness discussed above. It's my belief that many of us are in the same boat. I've now spent several years trying many iterations of power amplifier, preamplifier, source, cabling, speaker positioning, etc. While things are good, I have still not reached the promised land.

Assembling another system in a different room, where the same components can be tried there have produced far different sonics, and after time and time and time again, the process of elimination has taught even this dunderhead that "it's the room, stupid!"

It seems to me the eighthnerve products are basically copies of that. And, hey, if the design works, why not use it? The new line seems to replace whatever is inside the Room Tunes with probably something along the lines of fiberglass.

In my own instance, I have also chosen to copy the Michael Green Room Tunes design. My version will use burlap as the fabric, stuffed with long hair, carded wool. The wool comes from the tips from some very wise fellow members here on Audiogon. Material costs were under $50 total. The assembly of which should begin next week, as I have already lined up an upholstery shop, though I do not have the cost involved in this yet. Again, here's hoping it does the trick!

Trelja, you are correct that the Michael Green and the first generation Eighth Nerve products are very similar. The second generation Eighth Nerve stuff uses the same idea but is more effective. The idea behind these products is to trap the energy that goes into the corners. In order to do this the front surface reflects and the back absorbs with space around the edges to let the energy get behind. You will need to incorporate this into your DIY because without the reflective surface they will not work as intended.

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. Of course the journey is sometimes more fun than the destination so enjoy your project. It will be interesting to hear (pun intended) how well your version works.

I agree, most people when trying to deal with a room put in way too much absorption. Most recording studios do too. I think that is one reason most live recordings have an energy that most studio recordings lack.

If you look at the Eighth Nerve products and philosophy they only deal with the nastiness that comes back at you from the corners.

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.
