Perfect Speaker for Current Source Amps?

MikeW,
I am afraid I have not understood well: where did you get the PCB and the housing for your F1?
Do you drive the MMGs with the factory crossover (1 or 2 pole?) or did you adopt the series-type xover described in Nelson's article?
Best regards.

Hi folks.
Am I correct in my understanding that current source amps are
a good choice for driving insanely low impedances?
The reason I ask is that a pet project of mine some while back
was the design and building of a pair of ribbon headphones.
The design I eventually ended up pursuing was more akin to
a planar design approach in its use of an etched coil on polymide
ribbon.
This coil effectively gave me two ribbons sitting side by side and
a reasonable amp load.
The sound is nice and I would like to pursue further when time
and funds allow.
But, I have always fancied doing a ribbon using a purely conductive element.
So would a current source amp be the way to go?


Cheers


Mark

Some friend in the DIYaudio forum. I will have to look into the crossover. DO you have the schematic?


I don't think the MMG W have a crossover.

With a current source, the inductance of the voice coil vanishes
regardless.

A nice test would be a direct comparison of the two versions of the Veravox 5, which is available in 0.3 and 0.03 mH. An other question would be: Does the one with less inductance show the same performance with a voltage source?
