Bag End Loudspeaker Systems introduced at AES the Infra-MXB, a new-generation bass signal processor that is a single-space, rackmount stereo electronic crossover with mono sum Infra bass processing and surface-mount technology construction throughout. The processor features low-impedance, balanced outputs. The MXB low-frequency output offers dual integration and dynamic filter protection.
MXB dual integrators provide flat response down to 8 Hz when used with Bag End Infra Series bass speaker systems.
With the Infra technology, the electrical signal goes through the Infra electronics before the power amplifier, as it would with a conventional electronic crossover. Inside the Infra electronics, a slope is applied to the signal by the use of dual integrators lifting the low frequencies by 12 dB per octave.
The Infra loudspeaker is placed in a small enclosure providing a relatively high system resonance for a subwoofer. The system's response without the Infra electronic drive will rise at 12 dB per octave up to its resonance frequency and then flatten out until the woofer reaches its upper limit. When Infra drive is applied, the 12dB per-octave roll-off below resonance of the cabinet combines with the 12dB-per-octave rise of the electronics to form a flat frequency response down to the lowest point set on the Infra electronics. MSRP: $1,180.
