To follow up on this thread, I finally got my Rel subwoof... I mean, "sub-bass systems". Carbon Specials.
They sound superb with their stock power cords which are currently plugged in, but I will upgrade them soon as things can always sound better. I’m going to see if I can get a pair of 3M Audioquest Thunder cords, and a pair of 3m Hurricane cords, as demos to see if the cord quality actually matters. Truly hoping it doesn’t make a difference and I can go even lower grade. Despite the fact that I am firmly on the side of power cords making a big difference that is easily and blindly discernible on a revealing enough system, now that I have a bit of experience with my Rel’s, I’m not sure power cords will matter as much for subs. I have two reasons why this is my expectation, prior to testing:
- After correctly tuning and positioning my subs, meticulously checking for correct integration and balance with my main speakers, I tried playing them at normal volume with my mains disconnected. The subs are just whispering! It’s amazing that slight of a sound makes that much difference. Given that it’s just a mere whisper of supporting bass, I can’t see how power cords matter all that much.
- The upgraded Baseline Blue Speakon high level input cables which I purchased are comparatively cheap. If the signal cables are that "cheap", it seems like it would be weird to spend much more on power cords. These signal cables are even used with Rel’s even higher grade reference speakers. I don’t hear of audiophiles going crazy on higher level input cables for high end subs, so I really don’t see power cords being all that critical for subs.
I did find an old thread where the poster claimed that upgraded power cords helped his subs, in particular and surprisingly helping the mid frequencies and vocals. I am really, really hoping this doesn’t turn out to be the case for me. I have other uses for the cash!
