Expansive Sound & Sophisticated Aesthetics

The Motion 20 is a breathtaking visual statement regardless of its compact dimensions. Dual 5-1/2” aluminum-cone woofers are paired with a rear-firing bass port for extra punch in the low frequencies. With the addition of our exquisite Folded Motion™ tweeter it’s a design that delivers solid low-frequency reinforcement, superb sound dispersion and precise, highly dynamic high frequencies. Sitting on top included MiniETC™ Spikes, this combination creates audible acoustic alchemy across the frequency spectrum and offers an extremely expansive soundstage, richly detailed highs, and an open & revealing midrange.
