type WM-R30B.  These are 30mm square, 1.5mm thick and quote figures of 71dB
 SPL @ 30cms for 3V RMS input over a frequency range of 400Hz to 100kHz.
 They also do a slightly larger version with a low frequency response down to
 150Hz.  Unfortunately their published response curves only extend to 10kHz.
 They sound wonderful, if the figures are to be believed.  I would be
 interested to hear if anybody has checked them out.
