| It's a 64 foot stop, but I understand that it's not really 64 foot. From what I gather it's a covered/bent construction (I don't know the term) that gives a corresponding frequency response - 32′ combined with a 21 1/3. Hey, anything that has a fundamental of sub 20 Hz, I'm all for it.
There are, to my knowledge, two 64' organs, one in Atlantic City and one in Sydney.
I'm thinking some automotive pistons or gigantic actuators would be as efficient; we could simply shake the floor directly with machines insted of air. |
