I use a Cobra High Gear S-300. It's a mobile 4" speaker, I use on my base. It has a great sound, and cuts out about 75% of the noise when the button is pushed. Four years ago I paid around $35.00 for it on ebay. [photo=large]5382[/photo][photo=large]5379[/photo]
I have several of the Cobra series. S500. And the Uniden BC-20 (which has higher fidelity).
They don’t reallly have much in the way of noise filtering. Not when comparing to a true DSP unit.
But the audio reproduction beats that of a typical truckstop mobile unit by a mile. Which, along with some hiss reduction, is their strength.
Being able to mount the speaker in a vehicle separately from the radio can be a real advantage in a loud cab.
