MIDLAND-2 WAY RADIOS 21-406 20 W 4-Ohm External CB Speaker

Bring received CB audio out of the radio enclosure with a 20 W external speaker built for Midland MicroMobile CB radio installations. Its 4-ohm impedance identifies the electrical load required for the intended external-speaker connection, making it a focused accessory for operators who need audio reproduced away from the radio body. The speaker handles radio receive audio rather than providing any CB transmitting function. The 21-406 is specified for all Midland MicroMobile CB radios, fitting vehicle-based CB installations where radio placement can limit audibility at the operator position. Locating an external speaker closer to the driver or passenger area can direct incoming radio traffic into the cab instead of relying only on the radio's built-in speaker location. Installation requires an appropriate external-speaker connection on the radio and a suitable vehicle mounting position for the speaker. This accessory has a dedicated external-audio role within a MicroMobile CB setup. Its 20 W rating and 4-ohm impedance are the key electrical specifications to match when selecting a speaker for the intended radio connection. Use it where the radio is mounted under a seat, behind a console, in a utility vehicle compartment, or elsewhere that places the radio speaker away from the people monitoring CB communications.
