The Signature Elite ES20 is a two-way bookshelf loudspeaker sold as a pair. Each cabinet holds a 6.5-inch Dynamic Balance mica-reinforced polypropylene woofer and a 1-inch Terylene high-resolution dome tweeter, joined by phase-optimized crossovers at 2.4 kHz. The tweeter carries Hi-Res Audio certification and the stated response reaches 40 kHz.

Bass is handled by a bass-vented enclosure using the Power Port design, which is intended to smooth airflow out of the port and reduce turbulence and distortion. The cabinet is made from damped Medite MDF to limit internal standing waves and resonance. A magnetic grille is designed to reduce diffraction and can be taken off.

The speakers connect to an amplifier or receiver through one pair of gold-plated five-way binding posts. They work with 4 and 8 ohm outputs and are recommended for amplifiers delivering 20 to 125 watts per channel. Sensitivity is 86 dB at 2.83V/1m. Each speaker measures 14.8 x 8.5 x 13.8 inches and weighs 17 lbs.
