Pipe Organ Supplemental Low Frequency Systems

The largest and most impressive pipe organs have 32 foot long pipes to produce the lower frequencies. Some pipe organs do not have the longer pipes because of space and/or cost considerations. Supplementing the low frequency component of a pipe organ with electronics and loudspeakers is sometime done although many pipe organ enthusiasts see this as a unwelcome compromise, the difficulty is accurate supplementation. Typically since cost is the driving factor large vented subwoofer system have been used. They play loud but are not accurate systems. Conventional wisdom states that since the low frequency pipe of the organ and the typically large acoustical space it is located within has resonance and reverb; then a supplemental loudspeaker may also exhibit this behavior. The problem with this approach is that the electronic samples already have, contained within the sample, the resonance and reverb that makes the sound realistic. with this in mind the loudspeaker must be highly accurate to reproduce this complex waveform in the exact time and frequency relationship as the original sound. Bag End’s unique approach to subwoofers do this better and offer a no compromise approach to reproducing low frequency pipe organ sound. The cost is considerably less than actual pipes and offers surprisingly good results, even for the purest.
