Argent Room Lenses?

I've got four since my room is also being used for HT. I had to use two instead of the one that would normally go between the left and right speaker. I've found the thing that I like about the room lenses is that you can really tailor your sound by making very small adjustments in the locations of the lenses. Two inches makes a change in music presentation. My room had a bit of mid bass bloom and the lenses completely remedied my problem. I really didn't initially think that a positive would be their physical appearance but it is now probably the most impressive piece of gear in my room.

I made my own set of Room Lenses using the Jon Risch recipe combined with Greg Weavers steps and Thorsten filling recipe. Let me tell that after they were finished, they spend about a year between two audiophiles friends systems and almost lost them. They made fantastic results on both systems and on different positions. The actual guide from RL manual are just that, a guide to start. Final set up will depend on room, kind of speakers used and trial. The effect in my case is to give a huge soundstage, there are more details and clarity too. depending on the center lense position, the vocalist are presented at different deepness. The DIY can cost around $60-200 depending on the quality and finishing of the bases. Mine are finished in solid pieces of Red Cedar and were made by a wood specialist. There was my extra cost. Regarding the other materials, just plane PVC tubing (2") and pillow filling at Wal-Mart.

Yeesh, i've always thought that those things would be the end of any type of WAF in terms of room treatments. I find them pretty appalling looking myself let alone what a woman worried about "interior decorating" might think. Judging by the "bundles of praise" being heaped upon the results obtained by using them, maybe i need to visit Jon Risch's site again and build a set or two. If they work as good as you folks say, i might be able to live with the "fuggly" looks. Sean

Sean, I heard Jahaira's setup when I went back home. Those things *are* ugly, but very effective. Personally, I think I can (and presently do) get effective room treatment w/out them. I am successfully combining good tasting decor with acoustic treatments.

BTW, Jahaira has played around with *the* wood...

I am curious about these "things". How do they work? Where do you place them? Are they limited to a certain frequency?
Do they subtract sound? Do they add sound? Do they neutralize sound? Is there a way to measure a room for appropriateness? How do you determine how many you need? If they are all the same size, how could they possibly have such consistent success in such varying systems/rooms?
