Absorbtion?

While this may be heresy to some, I've found that a slightly asymmetric setup works best in an L-shaped room. The end result is based on a LOT of listening, as well as a great deal of computer simulation analysis.

In my case the right speaker (the one near a side wall) is a few inches forward of the left one. The speakers are also positioned so that the inside corner of the "L" is near the point of first reflection of the left speaker to help balance the overall presentation.

Now someone will tell me how horrible a sound this must create and burst my bubble. And after all that analysis...

Thanks everyone so far. The sound does get more harmonic in the perfect nearfield but highs are still subdued. I sit a few feet behind the ideal nearfield cause of room asthestics. Has to be the room, this is the 2nd setup and 3rd pair of speakers used. I almost feel like stripping the room, padding and rug (hardwood under) also and starting over in a live room. Also have a smaller room that is 11x16x8 closed in rectangle w/hardwood floors and sheetrock walls/ceiling. Not bad measurments to start with except the 16long and 8ft height (multibles are said not to be ideal). Dealer tells me this room is too small. Is this room too small for the Aerial 10t with 300W Classe ca300? This is a live room that can easily be set up using the Cardas Method and perfect nearfield triangle. This room can also be treated anyway i want. One long wall has a cement firewall behind it and easy to run a dedicated 20amp line or 2. I really don't believe everything my dealer tries to tell me. I know more than most of the floorpeople, but so does everyone else! Give me your blessings that the 11x16x8 room is not to small. I'll go for it, lot of work!! Spks will end up 36.432 from side walls and 59.136 from center of woofer to woofer (pretty close together for 10Ts) and 59.004 from backwall and 59.004 to listening position with 73.992 left behind listening position. Can any rocket scientist evaluate this? Will it work? I know try it and see, but a huge choir for me if the room is too small. Thanks Mike

IMO your room is not too small. There are other issues at work here, synergy being the primary I believe.
Not sure where you're going with the 'glass' question but certainly it reflects. I had a pair of split glass doors on my heavy wooden component rack (which I very rarely closed anyway). One day the cats were roughhousing & banged hard into one open glass door, stripping out a hinge woodscrew. In the process of effecting a repair, I removed both doors from the rack. The rig was playing & as I was walking around the house I noticed an improvement (a reduction of midrange glare, which I had been trying to figure out for some time). Following some brief critical listening, we decided that those glass doors were never again going to be installed.

Thanks Bob, i have 2 critters myself, love em to death. The glass is wall to wall behind the speakers presently in L shaped room. Can't figure it out, should be more revealing uptop, its not! Would really like to try setting up in 11x16 room. Lot of pressure will be in that room with this system.

Hello Mikec, I also have an "L" shaped room. I'm set up in the corner of the "L". Also have an open stair in the corner. 16ft long x 12ft wide with a vaulted ceilng 8-12ft. Thiel CS5i's, Classe CA-400, ARC LS-15, MIT 330 med bal, 330 shotgun bal, 770 twin cvt. I devided the length by 5th's. So my speakers are a bit over 3ft from the wall. I sit in a leather sofa against the opposite wall, about 9ft away from them. The speakers are about 9ft apart. For these speakers, I guess that I'm in the near field. I had to work on toe in with the highs. But everything sounds great. The only treatment that I use is a throw rug on the wall behind my speakers. My dealer told me to be careful not to "over" treat the room. I also have wall to wall carpet with a throw rug in the center. An "L" shaped room can work, it just takes a lot of placement to get it right. You might want to borrow a tube pre from your dealer to try with your CA-300. Good luck!
