Completing the most accurate point source solution available, B&C Speakers offers the FB464 passive crossover for our DCX464 coaxial compression driver. Specifically designed for use in conjunction with the ME464, 300Hz horn, users of all types can now have flat high-fidelity response out of the box using 100% OEM components. The FB464 crossover phase aligns the mid and high frequency elements of the DCX464, and implements an asymmetrical slope crossover at 3.6kHz without reducing efficiency. This crossover frequency best balances energy between the two diaphragms for minimum distortion at all output levels. Series protection is additionally provided by industrial filament bulbs which prevent over power or inconsistent tonal balance at very high output.
