This is still a bit of a secret, but here they are.


Small 30-W fullrange speakers. 7.5 cm. hi-fi drivers, crossoverless, embedded LM3886 Gainclone amplifier.


MP-15 final prototype (version 4.5), 55-22000 Hz frequency response, 9.5 cm. hi-fi fullrange drivers crossoverless,
simple preamp, LM1876 class AB amplifier (~15W).
The small speakers below the MP-15 are another prototype which was not that successful (they need better drivers).


Assembled with amplifier and line cable.

Class D amplifiers were also considered.
