That suggests a dielectric constant of well over 4 for the insulator, which is pretty high. Do they say what the insulator is ? As to whether it's 'perfectly capacitive', well the reactance of even 10m (5nF) of this cable only becomes comparable with the impedance of a typical speaker up in the megahertz region. It might tend to neutralise the inherent inductance of most speakers I suppose, but amplifers which depend on that inductance for their stability are perhaps best avoided in any case.
