Martin Logan Motion 20i Floorstanding Speaker Matte White (Each)
MartinLogan Motion® 20i
Floor standing speaker (Matte White)
Folded Motion Tweeter: MartinLogan's signature 1.0" x 1.4" Folded Motion tweeter utilizes an extremely low mass diaphragm that "squeezes" air, thus demanding significantly less excursion than the typical 1" dome tweeter. Its folded design also allows for a much larger surface area than compared to that of a regular 1" dome tweeter for controlled dispersion and low distortion characteristics. MartinLogan's Folded Motion tweeter is engineered to deliver much of the same high-frequency detail and speed of their large, dynamic electrostatic panel in a small space. This Folded Motion tweeter with advanced thin-film transducer technology offers a 40% larger radiating surface and 80x80 degree controlled dispersion for an increased audible bandwidth without sacrificing any detail and minimizing distortion to an unprecedented level, while also increasing efficiency and the tweeter's already lightning-fast response time. The result is a natural, realistic, and dynamic sound.

Dual Gold-Plated Binding Posts: The Motion 20i is outfitted with two sets of gold-plated binding posts allowing youto bi-amp or bi-wire the floorstanding speaker. These binding posts ensure a secure connection to many types of cable and connectors. The binding post terminals will accept banana plugs (single only), pin-connectors, spade-lugs, and bare wire (up to 10AWG). The binding posts are gold-plated for excellent audio signal transfer and resistance to corrosion.
Bi-Wiring: Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low & high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers; the lower set of binding posts are for the low frequency drivers).
Bi-Amping: Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.
Rubber & Spike Feet: The Motion 20i floorstanding loudspeaker comes with both rubber & spike feet. The rubber feet come pre-installed on the bottom of the speaker cabinet and are ideal for hardwood, tile, laminate, and vinyl flooring. The rubber feet can be removed and the included spike feet can be screwed into the bottom of the speaker cabinet. The spike feet are designed for carpeted floors.
Low-Mounted Woofers Minimize Floor Bounce
Floorstanding Motion models utilize 2.5-way designs that feature woofers positioned low in the cabinet and close to the floor. This deliberate design addresses a phenomenon known as floor bounce where sound reflected off the floor (from drivers positioned high on a cabinet), and those aimed directly at the listener interfere with each other. Without addressing these issues, listeners would experience bloated bass and massive increases and decreases in sound levels throughout critical midrange frequencies. Through careful crossover design and driver positioning, floorstanding Motion speakers deliver a flat, balanced response through the bass and midrange regions. Such considerations are crucial when seeking to achieve accurate reproduction of vocals and instruments such as kick drums.
