WARNING! Do not use your Ethos loudspeakers outside of the country of original sale—voltage requirements vary by country. Improper voltage can cause damage that will be potentially expensive to repair. The Ethos is shipped to authorized MartinLogan distributors with the correct power supply for use in the country of intended sale. -

After a short time, Rice and Kellogg had narrowed the field Today, most of us take the wonders of sound reproduction of “contestants” down to the cone and the electrostat. The for granted. - Page 21 In 1947, Arthur Janszen, a young Naval engineer, took part was very directional and its power handling was limited to in a research project for the Navy. The Navy was interested around 70 watts. As a result, many people continued to use in developing a better instrument for testing microphone box speakers with cones.
