This is a different speaker. But both the K2 speaker and the K3's are 
rated at 5 watts, are extremely sensitive (95 dB SPL), and have large 
magnets (shielded in the K3). No other internal speaker would perform 
better in this application -- I evaluated about a dozen of them.

Acoustics, amplifier characteristics, and filter bandwidths all 
contribute to the sound. In the case of the K3, the enclosure is 
larger, there's a new amplifier IC with very low distortion, 8-band 
receive EQ, and a much wider range of IF and DSP bandwidths.

We also plan to offer an external, front-facing speaker in the future, 
possibly with an optional power supply.
