A lower limit of 40 Hz is not that bad. The trouble is we only speak of fundamental tones and not the harmonics. A lot of instruments have second or third harmonic energy below 40 Hz. If it is a ported alignment, roll off below the 40 Hz FS will be 12 db per octave while a sealed alignment will be at 6 db. Trying to equalize the bass below the FS is tricky since it requires a great amount of power on the part of the amp and the ability to handle it on the part of the woofer. Only try moderate boost of about 4db. That will require over double the amp output than the non boost.
40hz ratings/speaker response
Hi, as a neophyte to the technical end of this wonderful addiction, I am curious. If a speaker's frequency response capability is rated to say 40hz or above, what happens to that sound that was recorder that falls below that range? Say for instance the lower octaves on an accoustic piano, or a cello, electric bass etc? And again, what happens to a speaker, with the same rating, if the volume is "pushed" to hear and feel music that has a lower range?
