The VOLT OHM 4.1 Outdoor Audio System transforms any backyard or patio into a full-scale entertainment space with rich, immersive 2-channel sound. This complete kit includes four ground-stake satellite speakers, one outdoor subwoofer, a WiiM-powered amplifier with remote control, and 100 feet of direct-burial plug-and-play cable — everything needed for a professional-grade outdoor audio installation.

The four satellite speakers feature 3.5-inch waterproof drivers with marine-grade PEI tweeters housed in UV-resistant dark bronze thermo-polymer enclosures. Each speaker is rated 5–100 Watts RMS with a sensitivity of 86 dB at 1W/1m. A pivoting arm adjusts 150° and locks in place for precise sound direction, and universal mounts allow placement via included 11-inch ground stakes or surface mounting. The subwoofer packs an 8-inch dual voice coil long-throw driver in a 14-inch diameter enclosure rated at 150 Watts RMS, with a frequency response of 45Hz–150Hz. It can be installed on the ground, surface-mounted, deck-mounted, or buried in-ground for optimal bass response.

The WiiM-powered amplifier delivers 2 × 100 Watts RMS with Bluetooth 5.0, AirPlay 2, Chromecast, and multi-room audio support through the WiiM app. It connects to any device wirelessly and supports optical, HDMI ARC, RCA line-in, and coaxial inputs. The full-function remote control adjusts volume, bass, treble, and media playback. The patent-pending plug-and-play 4/16 AWG cable connections eliminate wire cutting or splicing, reducing installation time significantly. The system is expandable up to 8.2 channels by adding VOLT speaker and subwoofer expansion kits. Backed by a 3-year warranty and FCC certified.
