Efficient Output with Reliable Cooling

With a 43 Hz Fs, 90 dB sensitivity, 5 mm Xmax, and low Vas, the PCS8-4 is built for useful output from compact bass systems. Its high sensitivity helps produce strong output from modest amplifier power, making it a good fit for powered subwoofers and small bass cabinets. Extensive venting through the voice coil former, pole piece, and under-spider area helps move heat away from the motor during demanding playback.
