How low is a piano?


I've heard that the open low string on a upright bass is about 42hz. Does anyone know where the lowest notes on a piano fall?

4186 hz

Hmm

higher than the crossover point for most tweeters...

another reason pianos are difficult to reproduce...
Supposedly, the two hardest things to record are piano and human voice -- not because of frequency range, but because they have wider dynamics (soft-to-loud) than all other sources. Anyone else ever hear this?
Reproducing piano on a speaker is an interesting subject. I've owned a lot of different speakers, and of all of them, I'd say that the ProAc Response 1 was the best at reproducing piano in a lifelike way. The thing is, it is a small speaker with limited low frequency reach, and it wasn't my favorite overall.
