help JBL Pro (Mid-Range) FAQ
Which JBL Professional subwoofer counts as a mid-range model?
JBL Pro is a brand family rather than one model, so the catalog entry needs a model number before its output or price can be judged. The 18-inch PRX918XLF is a common powered option, while the SRX818SP sits in JBL's higher-output SRX range.
How powerful is the JBL PRX918XLF?
JBL specifies a 2,000-watt peak amplifier rating, 1,000 watts RMS, and maximum output of 134 dB at one meter. Its selectable crossover settings include 80, 100, and 120 Hz.
Do JBL Professional subwoofers need a separate amplifier?
Powered models such as the PRX918XLF and SRX818SP contain their own Class D amplification. Passive models such as the SRX828S require an external amplifier and appropriate speaker processing.
Is a JBL Pro subwoofer suitable for a home theater?
It can deliver high output, but models such as the PRX and SRX lines are built for portable PA, live music, and installed sound. An 18-inch PRX918XLF weighs about 40.7 kg and uses professional connections, making it far larger and less domestic than a typical home subwoofer.
