@NickAlexeev well, it's definitely not audiophile-grade sound I'm after :P (only have one waveform I need to reproduce acceptably, and "acceptably" is governed by a FFT, not anybody's ears)
@NickAlexeev to speak more directly to "depends on the question" -- its mostly a matter of acoustics, the speaker isn't even 1lb so mechanical issues aren't a huge concern
