Is 75 ohm IC OK from AVR to subwoofer?

I am using a 3 meter (10 ft.) 75 ohm interconnect (Signal Cable brand) from my Denon 4308CI A/V receiver to a Velodyne DD-18 subwoofer. Is it OK to use the 75 ohm cable as an interconnect? Or will it

(1)Restrict the signal and negatively effect the sub's performance?

(2)Cause any problems in the AVR's or the sub's internal circuitry?

(3)Create any other problems?

Thanks for your help/ input.

Kirkus - two more issues I know of:

- coupled noise (in addition to ground loops) will cause voltage drops (returning to earth ground) appearing as a signal (since shield is used as a return - bad practice)

- cable is most likely made of low quality copper silver plated since signal at very high frequencies travels on the surface only.
