The PSM-800-T uses an 8" woofer and 1" titanium compression driver to serve up clear, powerful Klipsch sound for covered restaurant patios, outdoor bars, and other partially exposed commercial spaces. An all-new Tractrix® port design allows maximum bass response from minimum cabinet volume. The built-in multi-tap transformer gives you a range of options for distributing power to multiple speakers in a 70- or 100-volt installation. And the C-shaped bracket makes for simple surface-mounting and handy angle adjustments.
