The SUB18 is a high-output, 18" studio subwoofer from JBL that can be used for applications where high, continuous output and very low frequency response are required. With in-room response below 18 Hz and with a 137 dB peak output, the SUB18 is suitable for demanding dance music production as well as cinema post production applications. When used with JBL's M2 Master Reference Monitor system (available separately), the SUB18 allows three times greater output from the M2 system.
