Usher Audio
BE-20 Diamond
DMD Speaker
(Showroom Display Unit)

Overview

Usher Audio speakers and electronics are built for the experienced listener who won’t compromise on sound quality even at moderate prices. The exquisite Be-20 features 5-inch inverted-dome midrange drivers in addition to our unparalleled 1.25-inch Diamond DMD tweeters. Two 11-inch Eton Kevlar woofers power the bass, and time-aligned cabinets ensure any high-quality tubed or solid-state amplifier sounds its best. The integration, speed and clarity of these drivers uncover low-level detail usually lost in the noise floor of less resolving speakers. Dr. Joseph D’Appolito is our technical consultant providing guidance on crossover design, resulting in suave, powerful, transparent and engaging sound from beautifully crafted and lustrously finished cabinets made with leading-edge components at very affordable real-world prices.
