REL subwoofer cable

When I got my Rel B3 it came with a 35' cable. Hooked it up and after about a month I thought it was sounding good but not great. Then it dawned on me my speaker cables are only 10'. I cut the cable in half and to me it sounded a world better. But a couple of months later something didnt quite seem right. I measured the Rel cable and it was 16' long. Thats when I cut it to 9 ft. Its been well over a year and it sounds perfect. To ME (and NOT everyone will agree) all cables should be within 50% length of the rest of your cables. I can hear the difference IF AND ONLY IF I hear the same lengths first. In other words if your speaker cables are 10' then any other cables driving speakers should be no less than 5' and no more than 15'. I'm sure this will bring some differences of opinion. (Home theater would be the exception because of the delay you can add for the surrounds). To me the bass blends in better. Thats my thoughts and opinions. And I approve this post!!

Hi Al - here is why I wrote that
I have found the technical reasoning is thrown out the window in this hobby. I am an IEEE and there is no reason for why pc's ic's and speaker cables sound so different (better and worse than others). I did just gave my opinion and only my opinion. Specs for really any device cable or cord mean very little to me. I learned the expensive way not to read too deeply into specs.

Also years ago I was able to play with many different lengths of the same cables just to hear the difference. Some people would actually like the different lengths for it does give a slight 'reverb' which most people perceive the room to be bigger. Maybe I played around too much but it was fun with my audio dealer then.

More likely, the changes you heard were due to the lower d.c. resistance of the shorter cable length, which would have nothing to do with the similarity of that length to the length of the cables running to the main speakers.

Yes but to me and maybe I have become too critical of a listener but the lowest octaves didn't sound like they were aligned with the rest of the music.
Dont mean to start an argument. I'm just trying to relay what I have experienced in the past using my ears and not looking at specs.
