The Martin Logan Impression ESL 11A is a hybrid floorstanding speaker featuring an 11-inch XStat CLS electrostatic panel alongside PoweredForce Forward bass architecture. Its lower enclosure houses dual 8-inch aluminum woofers driven by dual 275-watt Class-D amplifiers with 24-bit Vojtko DSP. Constructed with an AirFrame Blade chassis, it includes Anthem Room Correction (ARC) support and dual bass trim controls.\n\nReviews consistently praise the ESL 11A for seamlessly blending its lightning-fast electrostatic panel with dynamic bass, eliminating traditional hybrid crossover gaps. Critical feedback highlights a vast, holographic soundstage, pin-point imaging, and ultra-transparent midrange. Reviewers note the powered woofers produce deep, articulate low end, with ARC room correction effectively neutralizing room acoustics.\n\nBy combining pristine electrostatic detail with powered, room-correcting bass, this loudspeaker delivers full-range performance without demanding ultra-high-power external amplification. The seamless balance of transient speed and low-end extension offers an engaging, live-sound experience in virtually any listening space, making it a complete, high-fidelity solution for demanding listeners.","brand":"The Music Room","offers":[{"title":"Default Title","offer_id":53236105478425,"sku":"99495","price":5799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/99495-4.jpg?v=1790120593","url":"https:\/\/tmraudio.com\/products\/martin-logan-impression-esl-11a-floorstanding-speakers-1","provider":"The Music Room","version":"1.0","type":"link"}
