L-Acoustics | SB15M WR - High power subwoofer: 1 x 15"

The L-Acoustics SB15M WR is the weather-resistant version of the SB15M, a compact, high-power subwoofer with a single 15 inch driver in a bass-reflex enclosure. It delivers up to 137 dB SPL with extension down to 40 Hz and is made for installations where the sound system is exposed to the elements. The SB15M WR is designed to complement the L-Acoustics Kiva II and XT series.

Deep bass for outdoor and exposed locations

Terraces, pool areas, sports facilities, theme parks and open-air venues all need a subwoofer that can handle more than an indoor space does. The L-Acoustics SB15M WR offers the same acoustic performance as the SB15M in a weather-resistant version, so you can add serious low end to outdoor and semi-outdoor installations without compromising on sound quality.

Compact, efficient and powerful

A direct-radiating 15 inch driver is mounted in a bass-reflex enclosure with L-Vents. These laminar-flow ports reduce port noise and improve low-frequency efficiency, keeping the bass clean and dynamic at high levels. With a maximum SPL of 137 dB (peak at 1 m) and usable response down to 40 Hz (-10 dB), a compact cabinet adds real weight to your system, even in open spaces where there are no walls to reinforce the low end.

Flexible system design

Use the SB15M WR as a single unit or combine several in a ground-stacked or flown array. With two or more subwoofers and the matching presets, you can create omnidirectional or cardioid patterns to control where the low frequencies go. This is useful in outdoor settings where you want to limit sound spill towards neighbours or surrounding areas. A built-in 35 mm pole-mount socket lets you place a satellite speaker directly on top.

Built for long-term use

The SB15M WR is based on the proven SB15M design, with a cabinet made of premium-grade Baltic birch plywood and a coated steel grille protecting the driver. It is made for professional use in fixed installations and demanding rental applications alike.

Typical applications

• Terraces, beach clubs and outdoor hospitality
• Theme parks, zoos and leisure venues
• Sports clubs, stadium concourses and campuses
• Open-air events and festivals
• Any installation where weather exposure is a concern

Pair it with

The SB15M WR works as the low-frequency extension for the L-Acoustics Kiva II and the XT series (such as the 5XT and 8XT). It is driven by an L-Acoustics amplified controller such as the LA2Xi, LA4X, LA8 or LA12X.
