electrostatic vs dynamic sound


hello !

i have recently moved my speakers( sonus faber olympica 3) to an open
floor living room and they started to sound terrible.

I have installed absorption panels on side walls and corners but they
didn't help much. 

Lots of echo .They literally sound like i was in hallway. I previously
had them set up in smaller room with lower ceiling and loved how their
sound.

I know that Electrostatic speakers may sound better in large , open floor area but i'm worrying  about sound "flavor"
Them most important thing i loved about SF olympica 3 was their extremely smooth sound . Very musical , not to bright,  more on the warm side.

i think about to trade them for Martin Logan Expression ESL 13A. they are in same price range.

is it a good idea ? anyone compared sf olymica 3 vs esl 13a ?

thanks !

You can get great help from GIK Acoustics. Also, try throwing around pillows and blankets between and behind the speakers as well as experiments to help you get a handle on it.

+++ everyone else. Where did you put the absorption panels and what kind are they? Did you treat first and second side reflection points as well as floor and ceiling? I’d think once that’s done the echoes would be significantly diminished.  I'd take Erik's advice and talk to an expert like GIK. 

Before you go crazy, give your ears and brain some time to acclimate to the new surroundings.
