Diamond Multimedia Mini Rocker Mono Red

I'm really disappointed that I paid nearly twice as much for this one as I did my Genius but the interference it picks up on the road is so annoying I can barely use it. Now it's more my "use at home" speaker.

The dynamic range is good for a beeping head. They claim 100Hz - 20,000Hz. That's a joke. The above claim - is probably +/-12dB which is irrelavant to human ear. Anyway, no deep lower and higher sound for you. Loudness is also far from 2W. I guess 0.7W...
