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 !

Over the last 40 years I've had dozens of speakers but always get drawn back to panels. I've had ML, Eminent Technology, Sound Lab and now Sanders 10e's. All have their pluses and minuses but the Sanders with their room correction is here to stay. They don't have the slam of big dynamics but dynamic speakers can't even come close to the speed or transparency or that feeling you are there IMHO.

I had to chime in. I think Sonus Faber is a fine speaker company and beautiful finish. But every time I hear a dynamic speaker I always hear the cabinet. Not to mention  drivers moving. I am also in the business and have sold the Olympica 3 speakers and many esl Logans . Including several pairs of expressions . I always love the huge open sound stage of a stat. The expression is a killer speaker for even three times  the price. I own Logans ,Sound labs and Focal speakers. Be glad to chat with you anytime about my opinion. 
Before you go crazy, give your ears and brain some time to acclimate to the new surroundings.  
+++ 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.

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.

If it is the room that sounds bad, changing the speakers won't cure that. Is the floor carpeted? One characteristic of line source speakers (planars) in their lack of ceiling bounce (limited vertical dispersion), but the floor is usually closer to the drivers, and can create reflections. If you have nice hardwood floors, put down an area rug. Try temporarily hanging a blanket on the wall behind the listening position to see if you are getting excess reflections off it. A mix of absorption and diffusion is what all acoustic consultants recommend.
