Does it make sense to use FIRmaker with an array driving two or more loudspeakers with one amplifier?

Many modern arrays and especially column loudspeakers already integrate amplifiers and DSPs directly into the cabinets. For such systems, FIRmaker optimization is tailor made. However, many other existing systems employ amplification and processing in separate components. In many cases an affordable hardware solution will be driving two, three or even four cabinets with one amplifier channel. Consequently, only one DSP channel will be feeding the signal to several cabinets at once.

AFMG understands the necessity of efficient system design. The FIRmaker algorithm thus can support optimization of pairs or even larger cabinet combinations – as long as this is intended by the loudspeaker manufacturer. However, it is important to understand that such combinations will only make sense in very large arrays. If the spatial resolution of FIR filter channels to the array becomes too coarse, the results of optimization will degrade. This is especially critical at high frequencies.
