Created by artist & industrial designer Joey Roth and hand-made in Portland, Oregon, The Ceramic Towers are premium-quality speakers made with extruded and billet 6061 aluminum, a copper inductor and cables, and plated carbon steel fasteners. They’re a mass-loaded transmission line (MLTL) design and feature SB Acoustics aluminum cone woofers. The 26” tall towers are designed to be used with Roth’s original Ceramic Speakers to produce dynamic, room-filling sound.
