Hands-on research

Product Research


Overview: The AQ-SPK2.0UN-4 waterproof speaker is a robust, durable, high quality speaker designed to withstand the harsh conditions of spa and hot tub use. Rated at 30 Watts RMS (60W peak power) and with a frequency response of 200Hz-20kHz, this compact 2" speaker can deliver clear full-range output and is ideal for installations with space restraints or for use in conjunction with larger speakers.

Waterproof Design: The AQ-SPK2.0UN-4 speaker is fully waterproof, as well as UV light and salt protected. It features a polypropylene cone with rubber surround and ferrite magnet, all housed in a durable ABS plastic enclosure. The speaker requires a cutout diameter of 2.22" and 2.25" of mounting depth. Along with the three screws provided for mounting, the speaker flange includes a pre-installed ring of 3M adhesive for providing a tight seal against the mounting surface.

Optional Grilles: The AQ-SPK2.0UN-4 doesn't include a grille, but is compatible with both the AQ-SPG2.0 and AQ-SPG2.0DB optional grilles (both sold separately).

Wiring: The speaker includes 20" of attached wire terminated in a proprietary 2-pin connector. If not using a matching harness, the connector will need to be cut off and the wires spliced directly to any additional extension wire.
