I stumbled across a very interesting article today or at least it abruptly caught my interest and attention: The Gentle Art of Room Correction I'm not trying to sell anyone on Meridian nor do I own any Meridian products... as a matter of fact I just purchased a Denon 2805 to play with. One of the several reasons I purchased the Denon was to test the Auto-EQ feature. In this white paper article (above link) it is suggested that equalizing above 250hz is not recommended and might even cause more problems than before auto-eq'ing. I've read a couple of reviews on the Auto-EQ feature on the newer Denon and Yamaha receivers but none that really get that technical as to how it's handled. It makes sense that it would only be beneficial for the prime listening position, but the article leads me to question if it can even be done in the right way for the prime listening position. It makes me wonder if Denon and Yamaha are just blowing a bunch of smoke to sell a product or is it really a useful feature? I do not know anything about the author of the article nor any of his credentials and not being that technical savvy myself wouldn't know if all of what he is saying is correct or not. If you have the time to read the article (it's not that long) I would appreciate your thoughts. Thanks!
