The 8MB700FT-NDY is an extremely efficient 8″ mid bass, due to its wide frequency band and 98 dB sensitivity rating, this speaker is ideal for pairing with compression drivers, on 3-Way system (with a suggested 95 Hz, 12 dB/octave high pass filter in place)! The large 2.5″ voice coil allows for the high 700 watts power handling and warrants the outstanding cooling system implemented into the motor.
