Product Description
The FBT PSR 212 Speaker features 13 ply Baltic Birch plywood construction
cabinetry in a trapezoidal design, internally braced to prevent undesirable
cabinet vibrations. A rugged touring grade scratch resistant black paint finish
protects the cabinet exterior.
A heavy duty perforated steel grille provides protection for the woofer and
horn. Strategically placed integrated carrying handles built into the cabinet
lend to easy transportability. Six ATM manufactured M-10 fly points are
provided allowing single speaker or multiple speaker cluster suspension. A 1
⅜” Speaker stand cup is built into the bottom of the cabinet for placement on a speaker stand.
The FBT PSR 212 is of two-way bass reflex design incorporating a Italian manufactured 12” FBT proprietary low frequency
woofer with a 4” voice coil with aluminum windings and a 2.6” B&C titanium compression driver coupled to a B&C
Aluminum 90° x 60° horn with a 1.4” exit. The internal crossover is constructed with a military grade dual flooded fiberglass
circuit board utilizing military spec components including metallized polyester condensers, and large diameter choke coils.
All crossover components are embedded in a special resin to ensure total imperviousness to vibrations in operation and
shock transmitted by mechanical impacts when transporting. The internal crossover allows either full range or bi amplified
operation by means of a jumper located internally on the crossover unit on the underside of the rear control panel input
plate. This type of selectable crossover frequency design provides against accidental crossover settings when either full
range or bi amplified operation is desired. When used in full range operation, the internal crossover frequency is preset at
1.6khz (24dBoct). Recommended amplifier power output when used in full range operation is 800w RMS total and 800 w
RMS LF, 160 w RMS HF when operated in bi amp mode. A sensitivity factor of 98.5dB applies in full range mode and 98.5
dB LF, 108 dB HF in bi amp mode. Frequency response is an ample 55Hz – 18kHz.
The rear facing input panel provides 2 Neutrik® Speakon NL-4 female connectors. FBT’s S.T.E.P.® (soft trip electronic
protection) circuitry ensures correct speaker operation even in overdriven conditions.
