Designed as a general purpose bass driver, and embodying the same principles as the smaller units.  The combination of an extremely powerful magnet system and excellent heat dispersion results in a maximum continuous RMS power rating of 100 watts.  The rigidity and low mass (28 gm) of the cone ensure an exceptionally good transient response and very low distortion - a "FAST" bass driver.  Typical free air cone resonance is 26 Hz: voice coil options are 4, 8 and 16 ohms.  This bass driver precisely complements the Bandor-50 to form a full range high fidelity system in which remarkable transient response and tonal accuracy extend over the complete audio spectrum.
