JBL SoundFactor SF15 15" 2-Way Passive Loudspeaker Cabinet - 250W RMS / 1000W Peak - Single

Up for sale is a used, single JBL SoundFactor SF15 15" 2-Way Passive PA Speaker. Built right in the USA, the SoundFactor series is heavily favored by working bands, rehearsal studios, and mobile DJs for combining authentic JBL component engineering with a highly durable, road-ready footprint.

This passive enclosure features a high-efficiency 15-inch low-frequency driver built with an advanced edge-wound ribbon voice coil alongside a ferro-fluid cooled titanium diaphragm compression driver. Rated to handle 250 Watts Continuous / 1000 Watts Peak power at 8 Ohms, the SF15 handles high output beautifully. JBL’s built-in SonicGuard™ protection circuit automatically safe-keeps the high-frequency horn from excess power surges without interrupting the audio performance. Because it is a passive box, it requires an external power amplifier to operate, making it a perfect, cost-effective replacement or mono fill extension cabinet for an existing PA setup.

Condition Notes: This speaker cabinet is in Good Used Condition and is 100% fully functional.

• Performance: Fully audio-tested. The 15" woofer plays tight and clean, the compression horn provides excellent vocal and top-end articulation, and the internal crossover network runs safely.
• Cosmetics: Shows standard cosmetic signs of regular live use and transit over the years. The black protective carpet wrap shows expected light fuzzing and scuffs, and the powder-coated 18-gauge steel grille shows minor cosmetic surface marks (please see all detailed photos).
• Connectors: The rear connection plate is solid, featuring parallel Neutrik SpeakOn and 1/4" TS phone jacks for effortless cabling and daisy-chaining.
