More details on the Aquatic AV AQ-SPK3.0-4C

Product Research


Overview: The AQ-SPK3.0-4C 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 (45W peak power) and with a frequency response of 120Hz-20kHz, this compact 2-way 3" 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-SPK3.0-4C 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 2.88" and 2.187" of mounting depth. Along with the three screws provided for mounting, the backside of the speaker flange includes a pre-installed rubber gasket for providing a tight seal against the mounting surface.

Optional Grilles: The AQ-SPK3.0-4C doesn't include a grille, but is compatible with both the AQ-SPG3.0 and AQ-SPG3.0DB 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.
