Realistic sound is a challenge. It takes a room length of sixty-four feet to permit full wavelength of a pipe organ tibia pedal. This is without a doubt the most challenging instrument to try and replicate the sound from. A direct shot the full length of the rig is the best place to mount a subwoofer speaker. My home stereo has an old Ampzilla amp. When I get serenaded all night by Oom-pah oom-pah and a quavering nasal whine describing infidelity and then loneliness I haul the horns out on the patio, max out the Ampzilla and treat one and all to 120db of Bob Dylan's Mr Tambourine Man. Jesus told me several zombies with hangovers reported it made them feel like commiting suicide.
