Technology header click

The new James Loudspeaker OT88Q is a high-performance tower speaker designed to deliver concert-level performance outdoors. The OT88Q features a titanium quad array tweeter for wide dispersion and crisp fidelity. It includes dual 6.5” woofers for detailed midrange and its sealed bass enclosure with dual 8” subwoofers is bi-amped for a smooth and powerful bass response. The OT88Q's robust engineering and design allow the James Loudspeaker Outdoor Tower speakers to effortlessly deliver high SPL playback over extended periods of time.

The OT88Q is a bi-amplifiered design so 2 channels of amplification are required for every speaker.  Bi-amplification allows for more power delivery and maximum output capabilities.

Any Outdoor Tower speaker can be installed using our internal mount (a beautifully hidden mounting solution for permanent installation into hardscape), or external mount (a wider mounting plate, best suited for permanent landscape installations, or for moveable hardscape installations). For simplified installation and configuration, James Loudspeaker offers optional custom wiring harnesses. The speaker also has access through the front grille for easy in-field servicing.

This model includes the OT-BRK-EM, external mount for use on flat surfaces, landscape areas and burial applications. For a smaller footrprint when the speaker will be fastened to a hardscape, please order the optional internal mount, OT-BRK-IM. This option requires fastening to the surface.

Each OT88Q Outdoor Tower may be ordered in low impedance or 70V configurations. Can be built to custom height, up to 96” (50” minimum). Available in 10 standard finishes or infinite custom finishes options.
