Dynaudio BM6A Active Studio Monitors (Single) - 7"The BM 6A features an electronic 4th order phase aligned crossover with a crossover point at 2. 2kHz, which feeds two high performance discrete MOSFET amplifiers rated at 100W each. The low frequency section is driven by a low frequency equalizer offering a choice between extended, critical damped response or more conventional higher Qt response for more level but less low frequency output. Included in the electronics is a complex protection circuit,
