Martin Logan Aerius Floorstanding Speakers – Black

Here we have a pair of Martin Logan Vantage hybrid loudspeakers. Combining electrostatic technology with a moving-coil woofer for the bass foundation. These units are in good condition, noting a small amount of wear to the rear of the units – please refer to photographs. They come with our regular three month warranty and will be suitably packaged with manual, a pair of power cables, but please note they will have to be shipped on a pallet or if you prefer personal collection would be welcome.
Martin Logan Say….
Open your mind to a new reference standard for musical clarity, power and intelligent size.
Close your eyes and hear. The sensation you feel is an unswerving commitment to music in its highest form of reproduction.
Open your ears and see the performance. The culmination of a decade of advances in electrostatic and hybrid loudspeaker technology, the Aerius offers you an uncompromised, yet affordable new reference standard loudspeaker that reveals everything within the music.
Advanced integrated technology now allows uncompromised performance to be housed in a package that requires only one square foot of floor space. With a height of just over 55″, the Aerius is even less imposing due to the 60% optical transparency of its electrostatic driver. And unlike traditional reference speaker systems that need to be placed four feet from the wall, the Aerius can be as close as one foot.
Optional double 5-way binding posts on the back of the cabinet provide easy access and the choice of single amp use or bi-wire capability. The bi-wire option also permits passive bi-amping. Additional technological convenience is provided by the high sensitivity and stable impedance curve that allows the Aerius to be driven by any well designed amplifier on the market today.
The thin film membrane is curved in a 30-degree continuous arc, to obtain a smooth, even dispersion with no hot spots. This elegantly simple, yet daring solution allows uncompromised operation of the incredibly precise electrostatic concept.
Every element, from drivers to crossover components in the Aerius has been carefully designed and selected by our engineers and built to meet strict specifications. For example, four separate computer programs were used in the design of the woofer for the Aerius, including extensive in-house development to optimize each woofer component for an ideal relationship.
Because traditional electrostatic stators often flex, stretch or ring, we designed an extremely rigid metal system and a special insulation application with exceptional damping characteristics that allow safe operation up to 10,000 volts. The thin film diaphragm housed inside is treated with a highly advanced conductive surface that has been vapour deposited directly into the polymer membrane.
When you look closely at the back of our electrostatic driver, you will see advanced pressure compensation technology that permits tone shaping in the diaphragm of + or – 6 dB without the use of an insertion loss crossover. Because no crossovers are used above 500 Hz, phase shifting and associated distortions are eliminated.
Aerius reveals the subtle difference between good sound, and great sound.
