Re-Post: Help? only one subwoofer channel works

Can I ask what kind of sub do you have and how is it hooked up ?

Uncommon ground?

My sub is the very cheap, not very good Tube Audio Design Aural Ecstasy unit. I have it hooked up high pass, straight from my Trends Audio t-amp to the sub's speaker terminals. This sub has already had a faulty amp that had to be replaced, which TAD did so even after the warranty passed, so no complaints. Both channels of the sub were working fine, until after I had to disconnect/reconnect it a couple of times, and I think at some point I might have put too much downward pressure on one of the left binding posts, perhaps causing it to touch something internally leading to a short. That's all I really know. It may well be something else.

I'm just wondering what the sonic effects of having only one channel of low bass. I guess it also occurs to me whether it is OK for a differential load being demanded on the amp, since now the right channel is driving both the main speakers (Tekton Design) and the sub, while the left channel is only driving the main speakers. Hopefully, since the sub presents such a small load to the t-amp, this isn't a problem, but I do wonder about the sonic effect on only one channel of low bass, as I put it in my original post.

Thanks to you both for your responses.

While it might not still be under warranty, maybe it might be a good idea to send it back in and see if something is wrong with it ?
