Ohm Walsh Micro Talls: who's actually heard 'em?

I actually removed the grill/can on one of my Ohm speakers to find out if it was interfering with it's sound and could not detect any difference.

The first piece on this CD is a good demonstration of how well the Ohm's can reproduce the sounds of a pipe organ.

The issue I have with the OHM 5s is largely attributable to my L shaped room. Bass levels are up to snuff with the 100.3s in the smaller room towards the front of my main listening area but drops off further back. This is the L shaped room with thin carpeted concrete foundation floors where the OHMS sit in the short end of the L firing into the long length, where most listening is done (see my system photo with the Jack Russell Terrier adornment). In the short end of the L and just in front, bass levels are good...further back they drop off.

I have the Ohm 4XO cabinets with the Walsh 5Mk-2 drivers on them in a room that's 16' X 24'. The speakers are centered on the long wall and spaced 6.5' from each other (center to center). There is only about 11' of back wall though, because of the open format, I have no idea how this is affecting the bass response. Maybe it's a trade-off, bass not as good as could be but less standing wave problems.

Some years ago I called OHM and asked John what amp. he would recommend that would make these speakers sing, he recommended the Sunfire Signature so i picked a used one up on Audogon and a used Legacy preamp.as well and have (on occasion) had it up to 75% gain, they handled the power without a problem.

The most remarkable audio illusion I experienced with the Ohms was when I was listening to environmental CD of breaking surf with the sound of seagulls, with eyes closed the room disappeared, it sounded as if I was really there on the beach. If salt air and a breeze were added I think someone could be fooled if they did not know better.

I remember one time using an Audio Control C-101 equalizer to EQ my system's room response so it measured flat. The Audio Control unit came with a microphone and automatic EQ software to enable this to be done.

The funny thing is the results absolutely sucked, and the Audio Control manual (which is perhaps the best manual I've ever read...helpful and humorous at the same time) said they'd probably suck.

I'd be very surprised if most listeners would really prefer flat room response given the opportunity to A/B the options.

Good hearing does not have a flat response.

I'm at a loss on what is really meant by a flat room. For instance, if the room is flat (at the listening position) according to a mike/meter in witch the mike has been calibrated to be flat, then to the human ear the room will not sound flat, because human hearing is 'not' flat. Now if the mike is calibrated in such a was as to match the way human ear hears, then the room should truly sound flat. Or am I missing something?

Al--I see. What I thing comes much closer to reaching that goal is to listen to binaurally recorded music with headphones. I wish there was a large selection of such recordings. http://www.youtube.com/watch?v=WRih10xLhD8&feature=related.
