Optimal Audio CUBOID 3 BTX Pair - The Cuboid 3TX passive speaker pair, full range, dual-channel, is a solution designed to provide exceptional sound in a compact format, ideal for background music and speech applications. With an attractive design and included mounting hardware, it can be installed both vertically and horizontally. Additionally, it features a protective cover for terminals, offering IP54 protection for outdoor use.
Cuboid 3TX includes a 3.5” low-frequency driver and a 0.5” PEI tweeter, mounted on a waveguide for even distribution of high frequencies. It can be connected to a 70V or 100V system, with tap selection via a rotary switch. For enhanced bass performance, it can be combined with Sub 10 and SmartAmp or Zone powered for amplification and speaker protection at high sound levels.
Setup and control are simple with Zone and WebApp, and ZonePad controllers can be added for additional control.
