It is the wire to the driver directly that has to be short. You are wiring to the higher impedance of the amplifier input so it should not matter. If the subs have a balanced input it is far superior to run a balanced cable from the preamp.
Sub Wiring
I currently run separate speaker wire from my amp (Luxman L-590AXll) to each of my stereo subs (Hsu ULS-15 Mkll). I use the same binding posts to run my speaker wires in what I guess would be considered shotgun fashion. A fellow audiophile told me he just piggybacks off of his speaker binding posts to each sub in his system.
I hadn’t thought of doing that, but it seems reasonable- less wire in my living space, and less chance of RFI being picked up along the way. I should add that the run from amp to speakers/subs is long- about 23 feet. My subs are within two feet of each speaker (Spatial Audio M3 Turbo S).
I am extraordinarily happy with the sound I’m getting, and this is really more of an aesthetic/RFI concern question. I’ll throw in that I wonder if electically this different hookup presents a different load to the amplifier?
This may fall into the “if it ain’t broke, don’t fix it” category of things. Just curious if anyone else does this…
