How low can you go in a room? (BD-Design)

Slightly off topic,
There is a solution for extremely low response in a small room.
I am sure you have heard of the rotary sub woofers. Certainly an extreme brute force device. How to reliably measure response and distortion at such low frequencies has me baffled, Perhaps a balloon and a high speed video camera?
Link posted for entertainlent value. This is insane. It makes me laugh, as in a Dr Frankenstein "It's alive" type of laugh... I don't think a valve amp's filaments would last long in this room.
