Product Description
The SoundFactor Series provides everything that makes a speaker perform & sound its best - and nothing that doesn't. Tough construction, great performance, gentle on your budget - that's JBL SoundFactor. JBL selected rugged and acoustically superior materials and components including the same kind of advanced crossover network that JBL applies to top-of-the-line systems.
SoundFactor networks shape the frequency response for coherent summation in the critical crossover region for better mid-range clarity and more consistent coverage at all frequencies. Onboard SonicGuard circuitry absorbs excess energy from dropped mics or feedback without interrupting the performance. No circuit breakers to reset, no fuses to replace, and no 'poly-switches' to degrade sound quality. JBL developed Progressive Transition waveguide horns to provide the best coverage, low-distortion, and frequency response.
Then there's the 100-hour torture test: when JBL specifies SF series speakers as having 250 watts continuous power capacity, that means they have passed a grueling, 100 hour test withstanding 250 watts continuous and 1000 watts peak power. No one in the industry uses a more demanding standard.
For compatibility, all SoundFactor models provide Neutrik¬ Speakon¬ and Õ in. input connectors.
Features:
Dual 12 inch, band-pass design.
The rugged enclosure is constructed from 19 mm (3/4 in) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for durability and improved lowfrequency performance. The enclosure is covered in black carpet.
Heavy duty, all steel handles are used.
Four detachable, swiveling casters are included for easy transport.
A top mounted, cast aluminum 35 mm pole mount receptacle can receive the included 24 in. (610 mm) pole to facilitate use of the SF22SP as a base for a midhigh speaker cabinet.
Built-in 500-watt (peak), 300-watt (continuous) amplifier. Controls, connectors, and indicators are clearly labeled with large, highcontrast graphics for easy operation in poorly lit environments.
Integral, preset limiter prevents clipping distortion. An LED illuminates to indicate that limiting is taking place.
Line-level stereo inputs are summed before being sent to the subwoofer's internal amplifier. This feature allows the SF22SP to operate in stereo systems using a single subwoofer.
An integral crossover also provides balanced, line-level, stereo, high-passed outputs to feed powered satellite speakers or an external amplifier for passive satellites.
A speaker-level, 1/4 in. TS phone jack is provided. This input is useful in applications, such as those employing powered mixers, in which it is more practical to bring a full-range, speaker-level signal to the subwoofer amplifier.
The SoundFactor SF22SP is a dual 12 in., powered subwoofer using a fourth-order symmetrical band pass enclosure design. A built-in 500 watt (peak) amplifier accepts stereo or mono line level inputs via balanced, XLR connectors as well as single channel speaker level input via a Õ inch phone jack. Integral signal processing includes a stereo crossover and limiting for the internal amplifier. A pair of XLR output connectors may be used to pass the input signals to another system or to send a high-passed, line-level signal to a pair of powered, full-range speakers. The SF22SP is designed to supplement and extend the low frequency performance of full-range systems in live sound and music playback applications. It is an excellent choice for use with powered full-range speakers or in systems using powered mixers. The speaker is configured for vertical orientation, but may also be used horizontally.

JBL continually engages in research related to product improvement. Some materials, production methods and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
