PBG18 Performance & Build. PBG18 is a passive 8-ohm 18" pro sub with a 4" KSV voice coil, 100-oz magnet, and vented MDF enclosure. Rated 1,000W RMS / 1,500W program / 2,000W peak with 98 dB sensitivity and 35 Hz-4 kHz response. Cabinet measures 20" x 23.62" x 25.59" and weighs 64 lbs. Features steel grille, carpeted finish, recessed handles, rubber feet, pole mount, and parallel SpeakON/1/4" I/O.

Isolation Platform Specifications. The ISO 12-18 isolation platform measures 30" x 20" x 1.75" and is constructed from high-density acoustic foam designed to support up to 350 lbs. It is intended for placement under 12", 15", or 18" subwoofers to separate the cabinet from floors or stages.

Connectivity & Deployment. Parallel 1/4" and SpeakON input/output connections allow straightforward daisy-chaining or routing from a power amplifier. The integrated pole mount supports mounting a full-range cabinet above the subwoofer for vertical system alignment. MDF construction with internal bracing supports consistent enclosure performance.

Use Cases & Setup Notes. Suitable for live sound, DJ, rehearsal, and installed audio applications. The PBG18 can be used individually or in multiples depending on system requirements. Typical setups use a low-pass filter in the 80-120 Hz range with appropriate amplifier matching based on the 8-Ohm load and 1,000W RMS rating. The ISO 12-18 platform is used beneath the cabinet on hard surfaces.
