Customer Reviews of DIAMOND MSP50 Speaker System - 2.2 W RMS - Black - 100 Hz - 20 kHz - USB
a 'look-alike' but not 'sound-alike'11/16/2012
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 at best.
