I purchased this speaker to use it with the Cobra 75WXST Weatherband CB Radio. The speaker on this CB is built into the handpiece, so I thought I'd need the extra volume to account for the small built-in speaker. However, it turned out that the built-in speaker worked fine.

When I received this speaker, the first thing I thought was, I can't believe how big it is. Before I received it I was planning on mounting it up under where the passanger would place their feet in the car (not under/inside the dash, but hanging from under the glove box), but it's just much too big to put there. Because of the size and how well the internal CB speaker worked, I chose not to use it and returned it, but I did test it out prior to returning it. It amplified the volume very well and you were still able to hear clearly at high volumes. However, I really can't imagine using this in a car unless you have a use for it that is not typical, or you're hearing impaired--it's that loud. It's sort of like going deer hunting with a bazooka, it's a tad bit of overkill. I could see possibly using it in the cab of a big rig, where you are exposed to more road noise, but that's really about it. Perhaps off-road vehicles too where you want to hear your radio while you're away from the vehicle.

Also, there is a volume control on the unit that isn't clearly pictured in the photo. In order to use it and have access to the volume control, you'll have to mount it within arms reach, so keep that in mind for your application. Even if it was small enough to fit under my glove box, I couldn't have used it becuase of the volume control location.

I blew through 2 other speakers from my local electronic/radio store before I purchased the Cobra. What a difference! Sound is much better, louder, and doesn't distort. I've had it for several months without any issues. Before, a little external speaker would only last about 30 days connected to my HAM radio.

First off you should know that this speaker is a good size. If you are looking for a little external speaker to make it easier to hear this is not the one. I have a Jeep Wrangler that never has the top on and usually not the doors. So when driving down the highway the stock CB speaker was useless. So I bought a little external speaker from Radio Shack that fit in the cup holder (told you it was little) this work fine for off roading and slow speeds but on the highway almost had to hold it to my ear to hear. Still needed an upgrade. Bought the Cobra HG S300. Like I said before it's bigger than you think. So hooked it up to see how loud it was, and it was plenty loud sitting on the E-Brake handle but not very stable or practical. Wound up mounting it to the roll bar between the front seats. And in that position I have NO problem hearing the radio at ANY speed. Usually have to turn the volume on the CB down a bit because it's too loud. The Noise Canceling is useless as it attenuates the volume, might be OK in a closed cab but useless to me.
And it looks nothing like the picture.
If you want a loud speaker so you can hear the CB this is the one you want. If your looking for just a little increase in volume or don't have alot of room this is not the one you want.

Speaker they sent was a cheap imatation. A real letdown from amazon. They should change the picture.

The speaker is great, but it looks nothing like the picture included with the item description. There is really nothing about that photo that is even remotely similar. I don't know if I got an earlier version of this speaker or what. Amazon really needs to correct the photo on this item.
