MartinLogan Impression ESL 11A hybrid electrostatic loudspeaker

Martin Logan Impression ESL 11A

ARC has one limitation, however... it’s software is PC only. If you are in a Mac-only household that might mean finding a PC-using friend who is willing to run the program for you. The software is also somewhat dense for casual users, and could do with more of an ‘idiot-proof’ pathway, because the world keeps finding new ways to make better idiots.

Whether or not you decide to use the optional PBK system, the Impression ESL 11A is one of the hidden secrets in the MartinLogan line-up. Some will miss this on the way to bigger speakers, but they shouldn’t. It’s a powerful, dynamic, musical fun maker with the usual MartinLogan characteristics of good imagery and great detail, but adds to that a relatively small footprint, and terrific integration between cones and panel. Factor in the benefit of subtle DSP room compensation and this electrostatic hybrid design comes extremely highly recommended!
