I have a set of the M12's, not sure if they are the same as the 1290's, which may have been an earlier version?
Here are the specs for the M12's:
Freq Resp. 34-22,000Hz, +/- 3dB
Impedence 4 Ohms, nominal
Efficiency 87dB from 2.8 VRMS (1 watt)pink noise output
measured at 1 meter in a typical listening
room.
Crossovers 200 Hz and 2000 Hz High efficiency LCR
Linkwitz-Riley design with 24 dB per
octave slopes.
Recommended amplifier power 15 watts minimum, 250 watts maximum.
I have all the info on the drivers, enclosure type and construction, grills and measurements if you want it, let me know. It's a lot to put on here.
