Best speaker for my HAM radio yet !! This is the most clear and understandable speaker I’ve tried. My hearing is not what it used to be and I have trouble understanding speech sometimes. I’ve tried 3 other speakers for my HAM radio and this one is easily the best of all. Highly recommended.
An Excellent External Speaker This is an excellent quality external CB radio speaker. The sound output is clean, clear and loud. I didn’t have any feedback problems when talking on an Astatic noise cancelling microphone hooked up to a Connex 3300 HP. It has a robust size and it’s not one of those small cheap speakers. I am well pleased. Highly recommended.
