RENAISSANCE ESL 15A

What makes a masterpiece? Is the “Mona Lisa” just a picture of a woman smiling, or is there more to it?

We consider something a masterpiece when uncommon skill and artistry shapes familiar elements in an unexpected way, revealing an essential truth.

For MartinLogan, the essential truth revealed by our skill and artistry is audio realism. Fittingly, our next generation of electrostatic loudspeakers debuts with the new Renaissance ESL 15A. Three decades of audio design and engineering innovation, distilled into a startling fresh loudspeaker ideal.
