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.

Herman, it's funny, but now I also CANNOT find the DIY Room Tunes information on the Jon Risch site. Although, I can still find other sites discussing his creation.

Anyway, the material of choice for the fabric he found to be burlap. Just about every other fabric was too reflective to do the job of absorption. Ah, but these things should often BE reflective, yes? Yes! That is why on one side, the devices contain a layer of polymer that provides that. You end up with one side that will reflect well, and the other which will absorb well. You try both in your setting, and go with the one that suits your environment, needs, tastes, etc. best.

While polyester batting was listed as the stuffing material, several knowledgeable members here have steered me in the direction of long hair carded wool as being superior to that, as well as foam and fiberglass. One thing I didn't mention is that it is going to have to be mothproofed, which should always be done in these circumstances.

The hard part will be the methodology in testing the effectiveness of the project. I don't just want to throw everything up in the room and sit down and listen. Rather, I intend to do this in stages, judging the effectiveness and need of each area and device in my room.

Pictures are no problem...

Shoe, thank you for providing the link. However, as stated previously, there is no longer any information on the DIY Room Tunes there.

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!

Funny, Robm321!!!

Unfortunately, I am one of the last anyone should be asking what the meaning of life is. Rather than giving a philosophical pile of mumbo jumbo about this or that, or a purely technical one like, "To propagate the species.", my answer would be along the lines of loud music, fast cars, and even faster women...

Anyway, some very knowledgeable people have told me in their experience of doing this kind of thing, and trying many a material, both foam and fiberglass seem to add an unnatural tonality to the sound. Wool, however, does not. In addition, in their opinion, the spectrum of attenuation it delivers is better than the other materials as well.

The reflective side is achieved by using sheets of polyethylene behind the burlap. Another tip was to use a fabric other than burlap on one side of the device, as they all proved to be on the reflective side according to Jon.

Some fun, eh???
