MartinLogan Motion 40i Gl
The Motion 40i is MartinLogan's mid-tier floorstanding speaker that delivers exceptional performance inspired by their legendary electrostatic designs. This three-way tower speaker features a Folded Motion® tweeter, a dedicated 5.5-inch aluminum cone midrange driver, and dual 6.5-inch aluminum cone woofers with rear-firing bass port. The proprietary Vojtko crossover network ensures each driver operates within its optimal frequency range, crossing over at 500Hz and 2,600Hz for seamless integration. Enhanced with drive-stabilizing dust caps, stiffened motor suspension, and strategically positioned low-mounted woofers, the Motion 40i minimizes floor bounce while delivering vibrant, accurate deep bass performance. The solid 18mm MDF cabinet with 31mm reinforced front baffle eliminates cabinet resonance. With its broad soundstage, pinpoint imaging, and extended frequency response, the Motion 40i offers audiophile-grade performance at an accessible price point. Perfect for dedicated two-channel listening or as the cornerstone of a premium home theater system.
