I have always thought that every piece of audio equipment I got needed to have the magic 20Hz to 20KHz rating. In recent reading on output transformers for tube audio I discovered that sometimes the push for hitting 20Hz sacrifices the transient dynamic response. And that got me to wondering just how much the music that I listen to ever dips below 40Hz. Some low piano notes can hit down there but are there other Classical and Jazz instruments that do much below 40Hz? Even classic rock never seemed to do much in the really low frequencies.
My stand mount speakers don't do anything really below 55Hz and while I do have subs to help out below that the music I listen to doesn't thump much. My subwoofers don't pound on my chest they just make the music sound a bit fuller in the lower end so if I stopped at 40Hz would I notice it?

I always find the chart a good place to start...

And keep in mind that just because an instrument goes that low, doesn't mean that it's used very often. Also, musical instruments are rich in harmonics, so while you may suppress the fundamental with a higher rolloff frequency, you'll still likely get all the harmonics and, as such, retain most of the character of that line in the music.

Hi, I agree that most music doesn't get much below 50HZ, But....and a big one I have my subs set for 12db/octave at 45 to play alongside of my electrostatics that are supposed to be -3db at 30HZ. They are naturally set for cut at 45HZ. I use a Behringer electronic crossover, passive preamp and a quad of matching Oddblocks. (no tone controls) Turning off the subs on a lot of music makes a huge difference. Light jazz, piano, strings etc it really doesn't matter, but pop, rock and folk music it does. YMMV

Good listening
Bruce
