Specifically, the Countryman B3 that I measured is down 3 dB at 19 Hz and a=
bout
7 dB down at 10 Hz.  That's consistent with the manufacturer's specificatio=
n of
"20 Hz to 20 kHz +/- 3 dB" from the data sheet here:

Not that mfgr. data sheets always have correct information!

Whether that is enough bass for your sound reinforcement application is a m=

of taste.
