Can the crossover point of a Bag End INFRA system be changed?
No. The crossover point cannot be changed since it depends on the resonant point of the INFRA subwoofer system. The INFRA processors allow altering the hi pass filter frequency by changing plug-in resistors inside the units of the INFRA-M and INFRA-M2. However, this does not change the true crossover point of the system and will, in fact, create either a gap or an overlap in the frequency response of the bi-amplified system depending on the filter frequency chosen.
