I wish they made a bi-amped active version of this monitor with a little bit more power.. Like Genelec 6010 but cheaper.

Thanks for your feedback Headzone. I wish these were bi-amped as well, though I'm not sure if it would make the sound any better, it's surely nice to have more power, in the non-passive set. Even Audioengine A2's are bi-amped, and they are smaller than the PM0.3. However I am not a fan of Audioengine's sound signature; too coloured and not neutral.

Hi,
I have recently bought 2 pairs of Pm0.3d,I'm using the two left hand speakers in a passive setup
with an external amplifier on an installation job.
I'm using the two active right speakers as my studio monitoring setup,so each speaker has the amp module in it,leaving the lefthand channels unused,
What I intend to do is bi wire and bi amp the tweeter from the unused left channel output in each speaker,thus doubling output power to the drivers, and giving the benefit of having a seperate psu for left and right channels,as well as doubling the capacity of the power supply.
I have also been experimenting using r/c lithium polymer batteries in place of the switchmode psu,the lipo cells are capable of discharging huge currents of 60 amps or more continously,and although the pm0.3 wouldnt draw anywhere near this current,having all that current on tap certainly reduces distortion on the peaks noticably,the batteries also dont have the rf hash that is inherent in a switchmode giving slightly cleaner performance on the treble end,to my ears.
The goal is to make a truly portable monitoring system,with a bit more headroom than the standard Pm0.3,all you need to do is cut a trace or two on the crossover board and wire in
the left channel on the tweeter,I'll let you know how it goes...
