REL T5i Subwoofer Hum issue


I followed all of REL’s suggestions on how to deal with hum but none address my issue. I’m using mine for stereo with my tube amplifier. All of the information I see or read just pertains to the left channel negative wire etc but the hum on mine appears to be coming from the red right positive channel. When I disconnect the right positive wire the hum stops dramatically and when I move the wire further away about seven inches or so, the hum stops altogether. I do have lots of wires and such around the area of the amp. Any ideas? I’m still waiting for a response from REL since it’s the weekend. 
Thanks

All the bass at low frequency is mono anyway. So don't connect it. Problem solved.

Don't believe me? Play some music you think has stereo bass. Okay now move the R to L and play it again. See how it sounds exactly the same? Because its mono.

I’m not sure why you’re moving things around. Recordings with stereo bass will have it coming more from one side than the other at times, depending on the instruments and how the recording was made. (I provided a few references to the science of stereo bass in another thread. The research on this goes back to the ’30s, at least. It’s really all about phase.)

Of course, if you set up your system with mono bass, then monophonic bass is all you are ever going to hear from it. That can be a very satisfying presentation and in some problematic rooms, it can be preferable.

It’s true that many LPs are cut with mono LF. But that doesn’t mean there’s no such thing as stereo bass. For example, I never sum the bass on recordings that I make myself. Yes, you can hear the difference.

In the earlier days of hi-fi, it was quite common for audiophiles to make their own recordings. I think it’s unfortunate that has fallen out of fashion, because the practice can give you a meaningful reference, and help you understand some of hi-fi’s common myths.
No cleeds, its not my system. My system if you would read my posts has five subs- two each on two amps, plus one self-powered. I’ve tried every combination you can think of for running those. You might also want to read up on the reality that all low bass is mono. Theoretically there might be some recording somewhere that is not. In practice no one has ever produced such a thing.

The "move" is to unplug the R from the R and plug it into the L. This is such an elementary first step standard trouble-shooting thing to do I just assumed everyone here would know about that. So okay, thanks for reminding me, lower the bar.
