JBL SF-15 Speaker

JBL SF15 Speakers

The SoundFactor SF15 is a portable, fifteen-inch, two-way speaker system designed specifically for applications in live music, music playback, and reinforcement of speech. With the smooth, natural sounding mid-range of the system, the SF15 does a great job projecting live vocals, solos and speech. The extended lows and great top-end make it at home for music playback in DJ applications or anywhere live sound reinforcement is needed.

Key Features

• JBL 15" low frequency driver 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 effi- ciency 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 the frequency response to deliver coherent summation in the crossover region.
• High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high power without saturating.
• Progressive Transition™ highfrequency 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 mechanical fastener technology for extreme durability and improved low-frequency performance.
• SonicGuard™ protects the highfrequency 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.
• Cast aluminum, 35 mm pole-mount cup for stand mounting.
