Martin Logan Purity

Purity marks an exciting new direction for electrostatic loudspeaker design. Internally powered with a 200-watt high-resolution switching amplifier, Purity allows an unprecedented level of system connection flexibility. Equipped with a standard RCA line-level input, Purity is able to connect directly to devices such as digital music players, flat screen televisions or even computers. Additional speaker level inputs give Purity the flexibility to work with receivers or other equipment that might not have a line-level pre-amp out option. Plug in your device and go!
MartinLogan pioneered the hybrid electrostatic loudspeaker some 25 years ago and one of the caveats has always been their power-hungry nature. To combat the issue, the Purity is the world's first fully-powered hybrid electrostatic. That's right, the amplifier, all 200 watts of it, is built to negate the need for costlier amps, allowing the Purity to be run off something as simple and common as an iPod. The internal amp is a bit nontraditional in that it's a fully switching digital amplifier rather than Class A or AB amps, which have size and heat constraints that would make a powered MartinLogan an impossibility. The Purity can still be powered by traditional means via its binding posts. The Purity features two six-and-a-half-inch aluminum drivers mated to its CLS panel, crossed over at 450Hz via its Vojkto crossover, giving it a frequency response of 41-23,000Hz. The Purity also features adjustable bass controls on the speakers themselves, allowing them to be better tuned to your room and listening needs for a more seamless presentation between panel, woofer, room and listener. Using the Purity's binding posts, the speaker boasts 93dB sensitivity. With the Purity's line level inputs employed, it has a reported sensitivity of 95dB at 0.1 volts/meter, making it hugely efficient and easy enough to drive to reference levels off an iPod.
