The Rockville RBG18FA is an ultra-efficient folded-horn, bass-reflex powered subwoofer for modern PA systems. Its integrated amplifier, onboard crossover and flexible connections streamline setup, while the folded-horn path couples acoustic energy for powerful, room-filling bass from a professional 18″ driver in a solid wood enclosure.Engineered for serious output, the RBG18FA is rated 750-Watt RMS, 1,500-Watt program and 3,000-Watt peak. The 18″ woofer employs a 4″ high-temperature, 4-layer voice coil with a 130oz magnet to produce deep, controlled lows. Frequency response is 25Hz-120Hz (+/-3dB), and maximum SPL reaches 135dB peak / 129dB continuous for impactful sub-bass.System control is comprehensive: a variable low-pass crossover (50Hz-250Hz), level and phase controls, plus balanced high-pass XLR preamp outputs at 120Hz to feed your tops. Connectivity includes balanced combo XLR/1/4″ TRS inputs and XLR thru/output jacks for parallel linking. Protection for over-excursion, thermal and clipping with status LEDs, along with a passive heat sink and auto turn-on variable-speed fan, maintain stability.
