Explore Sonance Outdoor Subwoofer 15-Inch LS15TSUB from Sonance. Start with the product's role in your setup, then check its specifications and installation requirements.
The Sonance LS15T is the larger outdoor in-ground landscape subwoofer in the LS family, delivering deeper low-frequency extension (22Hz-100Hz at -3dB) and higher sensitivity (98dB) than the LS12T — useful on larger properties or in systems that demand more low-end weight per subwoofer. The enclosure is vertically buried in the soil for simple installation, with only the top emitter visible at grade.
A polypropylene cone woofer with a Santoprene rubber surround supports high excursion for sustained output, and the Sonance Laminated Core Transformer (SLCT) offers adjustable taps up to 500W max so the same subwoofer scales across diverse system designs. The Laminar Flow Port reduces port distortion and improves overall frequency response. The UV-resistant low-density polyethylene enclosure is IP66 and MIL-STD 810 rated for long-term outdoor service in extreme weather.
The LS15T is the right choice when the LS12T doesn't deliver enough low-frequency extension or output for the property — larger lots, mature plantings that absorb energy, or entertainment areas that demand more bass weight per zone.
