SLAM technology gives the most powerful bass of any electrostatic Lower distortion improves spatial imaging and detail presentation 2nd Generation Carbon Nanotube Electrostatic Driver Premium materials for luxurious long-term comfort Compatible with all 580-volt bias electrostatic amplifiers SLAM Technology S ymmetric L inear A coustic M odulator — Tuned to enhance bass frequencies and lower distortion – Maintains optimal pressure distribution on the diaphragm – Patent pending. SLAM gives CRBN2 the most life-like physical bass of any electrostatic headphone, with natural detail presentation and immersive stereo imaging. Precision Crafted Each CRBN 2 is hand-assembled and tested in California by electrostatic specialists, finished to the utmost standards. Luxuriously Built CRBN² is engineered from materials of the highest quality: magnesium, carbon fiber, premium leather, stainless steel, and polymer acetate. High Voltage CRBN 2 requires an amplifier with electrostatic output using 580VDC bias, also known as “Stax Pro Bias.” A number of suitable amplifiers on the market from a variety of brands will drive CRBN 2 well , click here for more details. Heritage of Innovation CRBN² is based on a project to produce headphones for use in MRI machines, between Audeze and a team from UCLA School of Medicine. Due to the powerful magnetic fields of an MRI, the headphone could not use ferrous metals, so researchers developed the carbon nanotube film electrostatic driver.
