How well does MultEQ work at low frequencies?
This is one of the unique strengths of MultEQ. Room correction methods based on parametric equalization do not have enough bands or processing power to apply correction in the bass frequency range. MultEQ uses a unique implementation of FIR filters that achieves very good resolution at frequencies below those that standard FIR filters can reach. The resolution of the MultEQ filters varies with frequency and this allocates more of the filter correction power where it is needed the most: in the lower frequencies.
