Subwoofer accident? Sort of... and with sincere apology to Tubegroover: As a teenager in the late 60s I traveled around northern Rhode Island playing baroque organ at wonderful French Canadian churches sporting huge 4 and 5 rank organs (mostly made by the Casavant Freres of Quebec). I remember playing for a wedding service at St. Cecilia in Pawtucket, RI, one Saturday, and in the middle of the service saw a large shadow of a bird traversing the length of the cathedral below. It was a crow flying back and forth under the ceiling lights, casting airplane-like silhouettes on the congregation. Soon enough the entire crowd's attention was fixed on this aerial display, to the dismay of the wedding party. At the end of one pass the crow landed on the tallest organ pipe, a good 15' above my head. I reasoned that I could scare him away without disturbing the services by shaking him up with the 32' Bourdon. So I pulled out this mammoth stop, lowered my foot on the low C pedal, and felt the shudder of the 16Hz "tone" shaking the whole place. I suppose most folks assumed it was a truck passing by, or a mild tremor of some sort, but the huge infrasonic pressure wave startled the bird sufficiently to result in it falling down inside the organ pipe! Throughout the remainder of the service, to my horror, I could hear the bird rustling in the pipe, unable to get out! The priest and wedding party were grateful for the cessation of the aerial display, but I have never been able to forgive myself for this murderous note, and consequently limit myself to a sound system flat down to 32 Hz as penance! This is a true story...thanks for letting me get it off my chest....Ernie
