Hello!

Funny that you had such a negative experience. Have listened to mid size electrostats in anechoic chamber. Not bad at all. Quite the contrary! Brought along the fabulous "real" recordings on the chesky test disks; moving sources around stereo mics, LEDR and so forth. Never heard such a convincing 3D field before! Also felt like I heard every nuance of weakness in the source (amp&cd-player). The electrostats really shone when the rearside of the dipole just disappeared. Perhaps they're the ideal anechoic speakers? No Xover or multidriver interference issues. Did you listen to a good setup or is it perhaps possible that you heard issues with the playback system clearly? Many systems doesn't sound especially nice without a room to make it all gel (read: bass boost, haas wash out, reverb slosh).

It IS weird to be in such a room, but I had a very fun time and would love to do it again. In fact, wouldn't mind having it available as a reference for occasional "headset with speakers" checking if it had been possible!

IMO, I'm completely against placing too much absorption in a room. I know this is what some users think it is the correct thing to do but critical listening does not mean we are free of reflections.
Totally agree!

My room is extensively trapped. There's also a bit reflective surfaces, window in the front and lots of diffusion. Started out trapping the bejesus out of the room. It was sounding like a big headset, people used to make that exact comment! Without the usual bad sideeffects of a room. Very effective for getting work done. Going from an untreated room to a dead space removes a lot of those infamous veils. Have since added bits of reflections and quite a lot of 2D diffusion. It kept the precision of the dead room while giving a bit of euphonic envelopment. Engineers comment that it's not as dead as it looks with all the traps. The sound is more open and inviting, with the equally cliché word "airy" being a pretty good description. It's more fun to listen to, it's just as easy to get work done. Or more, as it IS more fun to listen to.. :D But I think a totally dead room is not a bad starting point either. IMHO, YMMV, etc.


Best regards,
