The passive 18" subwoofer JBL RX218S effectively complements the JRX full-range speakers in the bass range. The M118-4 18" woofer has a continuous power handling of 350 watts and a peak power handling of 1,400 watts.
The high efficiency of max. 133 dB and the impedance of 4 ohms guarantee an optimal adaptation to the JBL JRX200 full-range speakers as well as to the respective power amplifier used. The lowest, usable cutoff frequency is at 34 Hz (-10 dB).
By means of an optional stand rod, a satellite speaker can be placed on the integrated high stand flange. The active separation to the top should be at about 100 Hz.
