    Default Audio Cable Length

    I am looking to run a 25ft-35ft audio cable to my subwoofer (PSW505) I am just concerned about running a cable of this length with losing signal strength.

    I was wondering if this is going to be the case the cable will be bought from monoprice see link below...

    RG6U is used in the custom world for longer runs due to the ability of the cable design to carry signals long lengths without loss.
    This cable should be fine. I however use a much higher quality custom sub cable , it's 1.5% silver but still in the rg6Q design .

    For long unbalanced analog interconnect cables, the most important single factor is low end to end resistance of the return/shield.
    This is one example of a very good cable.

    In professional audio world you can run balanced audio signal up to 200 meters without much worrying. This length applies to both balanced line level audio interconnections and signals from dynamic microphones with balanced connectors.

    Analog audio cables may be used for digital AES/EBU audio, but only for distances (less than 10 meters). The impedance of most typical analog cables ranges from 40 to 70 Ohms. This large mismatch from the nominal 110 Ohms (digital impedance) results in signal reflection and jitter causing bit errors at the receiver.

    That 40 to 70 Ohms impedance (more likely 32 to 93 in co-ax) is the Radio Frequency Characteristic Impedance which doesn't fully kick in until almost 1 MHz. Digital AES/EBU and S/PDIF audio systems are very robust and for 10 meter cables large impedance mismatches are easily tolerated. Note that AES/EBU is a two conductor system not a co-ax system. Belden Wire suggests that if you use a 38 Ohm two conductor cable instead of the correct 110 Ohm cable, it should be good for about 50 feet
