    Thanks guys!

    2 x 2.5mm (13AWG)



    SUPRA Concentric Cables are highly flexible and of short pitch twisting for low inductance and low radiation as well as a high tolerance to frequent bending and vibrations before bending fatigue. This short pitch twisting takes special machines and is a slower and more expensive production which you do not often find in other than the Supra portfolio.



    Rondo wire is a good choice for all high end speaker applications, both external and internal wiring, hi-fi or stage.



    Heat and aging resistant PVC jacket

    2 conductor, 320 strands of 0.1mm wire

    Tin plated OFC

    External Size: 7.7mm diameter

    6.8 ohm per kilometer (3280 ft)

    0.4 microhenries per meter

    Those are actually limited run, kryptonian magnet equipped woofer. Pre "Bozo" model prototypes.

    I guess I did not realize I had to specify that the drivers pictured are for test purposes only and are not part of mod...

    *face palm* Sad day on the Polk forum.
