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.

Yup. No problem at all.

FYI, the 75 ohm figure is NOT the cable's dc resistance, or its impedance at audio frequencies. It is what is called "characteristic impedance," which only comes into play at much higher frequencies, such as digital signals that have fast edge rates, or video or radio signals.
