The Cobra HGS300 is a rugged heavy duty CB speaker with noise-canceling circuitry and 15 watts of power. Listen to the conversation on your terms. Whether you cruise with the top down on your Corvette, or are motoring over the road on a long haul journey you won’t miss any of the conversation with a Cobra S300 speaker. Separate noise canceling and volume controls allow you to tune in the important talk or tune out background noise as you see fit.

CB World customers rave about the superior sound quality of the Cobra HGS300. The noise canceling feature of the HGS300 makes this external speaker a popular choice for convertibles and soft tops.

A right angle 3.5 mm speaker connector allows mounting the HGS300 nice and tight against the dash or anywhere inside the cab of your ride. Single wire connectivity to CB radios, scanners, and other communications hardware that sport an external speaker out connection.

A 3.5 mm earpiece jack is a must when team driving. Let your driving partner rest in silence while staying in tune to traffic conditions and CB radio traffic.

The 180 degree ratchet mount makes mounting the Cobra S300 speaker to a variety of surfaces at various angles a breeze. Mount the bracket, attach the CB speaker to radio, and adjust ratchet for best sound in your car, truck, or RV.

I have instilled 6 CB systems for friends in our Thunderbird club and I have always used this speaker. Everyone raves how good the speaker is; the sound quality is superior; the sound is loud enough to hear going down the freeway at 70 MPH with the convertible top down. The compact size makes it perfect to either mount; to lay on the floor or in the seat.Over the years of being involved with CBs I have tried many other brands but none compares to this speaker.If you are looking for a great CB speaker this is the one!
