Miab, since what I became an expert in cables? I am as much as anyone else – a subject of accidental discovering...
I do not use in Injection Channel any fancy cables. There is not a lot of need for it. The Injection Channel is mixed with Macondo in respect to what Injection Channel does. Whatever it does including the cable, so, there is no need foe any cable experiments.
The cables foe bass channels is tough, ether internal or external. Most of the High-End cables tend to be full-range and not too good for LF only. It would also greatly depend from how far into midbass/upperbass your woofers in sealed cabinets go. I think the inductance in speaker cables is not relevant. You will have a microscopic inductance that will create a low-pass filter but the amount of this inductance is minuscule and the filter will be at many kHz. The inductance of VC of your driver will be order of magnetite higher than any inductance of the cables. In cable for bass I would watch for min impedance and lover capacitance. The cable capacitance is a high-pass filter and implicate is a waste of damping. Generally 8-10ga pure copper cable is a good direction to start.
I for my woofer towers use old version of Aural Symphonic cupper cable that I feel is better than Purist Dominus for lover bass. My towers are wired with 10Ga cooper with very thin isolation. Anyhow, you might find Gauge Resistance per foot info useful.
You might find the same info for aluminum, silver and alloys…The Cat
