The JBL-Control 89MS Mushroom-Style Landscape Subwoofer augments the low-frequency performance of the JBL Control 80 Series landscape speaker line (and other outdoor systems) to provide rich bass in lawn, garden, and entrance areas of hotels, restaurants and other hospitality and retail complexes, as well as theme parks, sports venues, resorts, entranceways, and anywhere a highly weather-resistant speaker is required.

This sleek, attractive, compact subwoofer features a down-firing, long-throw 200 mm (8-inch) driver which delivers 115 dB (peak) of clean, powerful bass down to 40 Hz. The built-in low-pass crossover features a dual-slope filter which begins with a gentle slope at the crossover frequency and transitions to a steeper slope at higher frequencies), creating a balanced subwoofer transition regardless whether the speaker is driven from a full-range or a dedicated subwoofer amplifier channel. The premium-grade dedicated-subwoofer-band multi-tap transformer (and tap selector with 8Ω bypass) allows the JBL-Control 89MS to be used in 70V and 100V distributed systems or driven directly at low impedance, for maximum versatility.

The JBL-Control 89MS is IP56-rated to withstand the elements, with a tough polyethylene enclosure and a fully-sealed center wiring chamber. The enclosure color extends throughout the cabinet so the speaker maintains color even when scraped or scratched. All external hardware is stainless steel, and the powdercoated stainless steel grille resists rusting.

The two-part enclosure is designed to open with a twist for wiring and then close securely with an included security screw. The bottom base section of the enclosure can be preinstalled and then wired to the top speaker section of the enclosure when the top gets installed. When assembled, the bottom base section becomes a fully isolated chamber, and the wiring/speaker chamber is further sealed by a water-tight bulkhead, keeping the speaker and transformer (in the top speaker section) highly isolated from the possibility of intruding moisture. Multiple locations on the bottom and sides are provided for the mounting of the exterior gland nut (installed by drilling a 22 mm [0.875 in, 7 /8 in] diameter hole in the chosen location), and a second, interior gland nut is positioned in the bulkhead between the bottom base and the top speaker sections to keep the speaker system highly weather tight. Included gland nuts maintain a water-tight seal only when used with round-jacketed cable with outside diameter between 4.0 and 9.0 mm (0.16 and 0.35 inches). The Control 89MS can be secured to the ground via third-party ground stakes using the three attachment points that extend out from the bottom section of the speaker.

The 200 mm (8.0 in) diameter long-throw subwoofer driver features a waterproof and highly corrosion-resistant polypropylene cone and long-excursion corrosionresistant TPV (thermoplastic vulcanized surround, and a large 50 mm (2-inch) voice coil on a glass fiber coil-former for high power handling and superior longterm reliability.

The speaker handles 150 Watts Continuous Pink Noise (300W Program, 600W Peak) in the 8Ω mode. The Control 89MS is UL certified, per UL1480A.
