JBL VRX918S-WH - 800W 18-inch Passive Front Loaded Subwoofer in White Finish

The JBL Professional VRX918S-WH is a compact, high-power subwoofer system designed for professional audio applications that require a blend of powerful low-frequency output and aesthetic versatility. Featuring an 18-inch JBL 2268H Differential Drive woofer with a neodymium magnet, the VRX918S-WH delivers extended low-frequency output in a front-loaded, vented enclosure. It is optimized for use in arrays with the VRX932LA-WH Line Array speaker and the VRX-AF Array Frame, but can also be used in arrays consisting entirely of VRX918S-WH subwoofers, offering exceptional performance across various configurations.

Designed with flexibility in mind, the VRX918S-WH can handle both ground-stacked and suspended applications, making it suitable for a range of installations. The white DuraFlex finish ensures it blends seamlessly into environments such as houses of worship, auditoriums, and theaters, where aesthetics are just as important as sound quality. The high-quality, heavily braced enclosure is crafted from 18mm, 13-ply birch plywood for strength and durability, while its large port area reduces distortion and ensures clear, accurate bass reproduction.

The VRX918S-WH is equipped with a built-in rigging system that makes it easy to connect to the VRX932LA-WH or to a dedicated array frame, offering convenience and efficiency in multi-speaker setups. A recessed, external switch allows for easy selection of either +1/-1 or +2/-2 contacts to suit a variety of cabling schemes. The speaker's 20mm threaded pole socket enables secure mounting with the optional SS4-BK pole, while the attractive CNC-machined 16-gauge steel grille, backed with acoustically transparent white cloth, adds an element of sophistication and provides additional protection for the driver.

The subwoofer's performance is complemented by a frequency range of 31 Hz - 220 Hz, ensuring deep, powerful bass response. With a sensitivity of 95 dB SPL at 1 watt/1 meter and a maximum SPL of 130 dB peak, the VRX918S-WH is capable of delivering high-output, distortion-free sound for large venues. The subwoofer's recommended crossover frequencies are 80 Hz with a 24 dB/octave high-pass filter and 80 Hz with a 24 dB/octave low-pass filter, ensuring optimal integration with the VRX932LA-WH or other system components. The VRX918S-WH's nominal impedance of 8 ohms allows for compatibility with a range of amplifiers, ensuring reliable and efficient operation.
