JBL PRX 818XLF 18 inch Self Powered Extended Low Frequency Subwoofer

JBL PRX818XLF
Powered 18” Extended Low-Frequency Subwoofer System with Wi-Fi
The PRX818XLF extended low frequency subwoofer was designed and engineered to provide sub bass frequencies with accuracy and power. Used as a single sub in a sub/sat system or in multiples as part of a scalable, large-format sound reinforcement system, the PRX818XLF performs with exceptional efficiency and control. The subs are stackable and lightweight, ensuring quick set-ups and tear-downs.

The addition of a polarity reverse option further enables system optimization. Due to their rugged construction, they are perfect for AV rental inventories. With the integrated stereo pass-thru this is the most powerful low-frequency complement to PRX full-range systems. PRX800 subwoofers feature a standard M20 threaded pole cup that can accept most modern subwoofer-mounted speaker poles.
