Coax or Interconnect to Sub!

[Sumbrada77]

Hello, I am a new owner of a VTF-2Mk1 subwoofer. It is my first subwoofer and it is quite a change. I put this questin into the Technical area also, sorry for double posting. Having that much low end is quite interesting.
My question is: I initially connected the subwoofer with an Audioquest coax
sub cable and Y cable (suggested in manaul). I have a single Audioquest Ruby interconnect (many steps up in quality over the coax). Can I use this to connect to my sub instead of the coax? Would a good interconnect be
better than a coax?

I'm using simple RG-6 quad shield terminated with compression RCA ends. Works great! Best of all I can terminate to the exact lenght I need or even run "in-walls" with the coax.

Your choice. Expensive wires are just that, "EXPENSIVE". Nothing more.
