My Bag End low frequency speaker has both Low and High banana jack inputs. Is there a crossover inside?
The “Low” pair of banana jacks are wired in parallel with pin 1+ and pin 1- of the Neutrik Speakon connectors and connect to the driver(s) in the enclosure. The “High” pair of banana jacks are wired in parallel with pin 2+ and pin 2- of the Neutrik Speakon connectors. This allows the use of a short jumper between the subwoofers and the mid/high speakers in a bi-amped system. Bag End subwoofers require the use of an external INFRA processor, which acts as the crossover for the system. Non-powered INFRA subwoofers do not include or require an internal crossover.
