The FBT Jolly Series speakers feature lightweight, yet rugged gas injected molded polypropylene cabinet construction. The asymmetrical shape of the Jolly 15ra cabinet also allows use as a powered floor stage monitor. The FBT Jolly 15ra is a two-way design incorporating a 15” low frequency woofer and a 1” High frequency driver coupled to a 90°H x 60°V horn. The active internal crossover is at a fixed frequency of 2k. With a frequency range of 60Hz - 20kHz, Jolly 15ra provides hi fidelity sound for both speech and music applications with a maximum SPL of 121dB. A front face steel grille protects the woofer from external damage. FBT’s ADAP® Advanced Dynamic Active Protection circuitry protects speaker/driver components against failure. The Bi amplified Jolly 15ra active speaker features a 150w RMS Class G low frequency amp, and a 50 w RMS Class G high frequency amp. The control panel features a volume control, a balanced Neutrik® input combo jack (female XLR, ¼” TRS, ¼”), balanced XLR link output jack, ground lift switch, LED power on indicator and limiter LED indicator.

The two M-10 fly points built into the cabinets, along with the optional Box 112 mounting brackets allow the Jolly 15ra speakers to be surface mounted on walls or ceilings. A standard 1? speaker stand socket allows the Jolly 15ra to be mounted on speaker stands.
