Subwoofer cable question

by wade627 / March 18, 2009 8:43 AM PDT

HI C-net guys and Gals great job you do here on the forums.Im sure its been asked many times can i use a composite yellow cable for my new subwoofer.I bought the energy Take classic (editors choice)and a 35 buck subwoofer cable which is probably a rip off but they will be here at separate times so will it hurt anything?I thought i read somewhere where there both 75 ohms and compatible.

I have never heard of an audio cable as being 75 ohm. I say..if it looks right, use it.

What a bunch of s&**@#, they fed you. Use any good quality RCA cable, plug it in and thats it. Composit75ohms? Yup. Come to the people at Cnet for a straight answer. 35 buck rca cable? The Brick (store) they tried to sell me a $145 +tax hdmi cable. What next?

Any RCA cable will do because the output for the subwoofer is measured in microvolts. The woofer kicks it up.

75 ohm cables are commonly referred as coaxial cable which feed audio/video signals to your components. (now replaced with HDMI cables--typically) You won't hurt anything by using standard grade RCA patch cables.

The biggest difference in subwoofer cables is the amount of sheilding they have from interference and naturally, the more expensive it is the more shielding it has and smaller loss of signal because they use thicker copper wire.

You can you a 75 ohn cable if you want to no problem.

The 75 Ohm impedance is only at RF frequencies, at audio frequencies it won't matter. John

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
