Cobra Extension CB Speaker

A great speaker. It's a perfect accessory to go with my Cobra 142-GTL Base station CB. The audio is actually louder than the internal stock speaker at any volume level. Right Channel Radio does it again!

Pretty good - much easier to hear than the built in speaker.

Unfortunately, there's no way to mount most radios that really points the built in speaker at you. Most of the cases these radios are in resonate poorly as well. This speaker is much easier to hear. That said, "flat response" is not a descriptor I'd use for this speaker, there are certain frequencies that are really poky. Still, I feel like the performance is fair for the price, and I'd at least consider this speaker again if I were purchasing another external speaker.

Good speaker for the price

Overall a good speaker, but even with my radio at max volume I still have difficulty hearing transmissions sometimes.

I recently purchased the Cobra

I recently purchased the Cobra Extension speaker, as I have hearing loss in my right ear, and hearing the transmisions with background noise can make it very difficult. The speaker solved that problem immediately. I now turn the radio down low and can hear everything perfectly. I mounted the speaker in my Peterbilt just behind my head above the door near the seatbelt spool. It made all the difference in the world for me. I highly recommend this speaker. S.D.F. Boston

Awesome speaker

This speaker was the first external speaker I have ever bought. And I am very pleased with its performance. I have had no problems with it what so ever.
