|Model Code||MQ 90S-B|
|Sound pressure level [dB] at rated power (1kHz, 1m)||101..110|
RCF S.p.A. MQ 90S-B is an 8-inch band pass black subwoofer that includes a transformer inside for the connection to (100 – 70 V) constant voltage lines, yet it can also be set to 16 ohm (low impedance connection). When connected to a 100 V line, its power can be selected among the values 60-30-15-7.5 W through a rotary switch (thanks to internal transformer taps). Unlike other models, that require all of the satellite speakers to be wired directly to the subwoofer, the MQ 90S-B can be parallel wired anywhere along the constant voltage wire pair.
