JBL - SF25 - PASSIVE SPEAKER SYSTEM 2000W PEAK / 500W RMS - 1" COMPRESSION DRIVER - 2 x 15" SPEAKER WIH 2.5" RIBBON VOICE COIL
The SoundFactor SF25 is a portable, dual fifteen-inch, two-way speaker system designed specifically for applications in live music performance and music playback. The dual fifteen configuration is especially useful for applications in which additional low-frequency power and extension is needed but adding a subwoofer to the system is not practical.
Key Features:
� Dual JBL low frequency drivers with a 64 mm (2½ in) diameter edgewound ribbon voice coil which provides more cross- sectional wire area in the voice coil gap than round wire designs, for greater efficiency and power handling.
� Ferro-fluid cooled compression driver with titanium diaphragm improves high frequency performance as well as system reliability.
� The advanced network topology crossover design shapes frequency response and delivers coherent summation in the crossover region.
� A “Quasi 3-Way” design offers the extra bass for which a dual fifteen
system is designed, but without sacrificing performance in the critical mid-range. The upper woofer produces mid-frequencies and bass, while the lower woofer concentrates on bass only. The reduction in mid-range phase cancellation greatly improves mid- range sound quality and coverage.
� High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high power without saturating.
� Progressive Transition™ high- frequency waveguide provides superior coverage control, reduced distortion, and smoother frequency response.
� The rugged, acoustically superior enclosure is constructed from
19 mm (¾ in) MDF (Medium Density Fiberboard) using advanced adhesives and mechani- cal fastener technology for extreme durability and improved low-fre- quency performance.
� SonicGuard™ protects the high- frequency driver from excess power without interrupting the performance.
� Non-resonant, all-steel handles are used.
� Attractive 18-gauge perforated, steel grille protects components from damage.

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 rea- son, 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.
