Subwoofer connection to older tube amp

Davidrb - Yes, it will work fine with a tube amp. I used that setup for a couple of years with and AES/Cary Superamp. The amp has five-way binding posts and I used spade connectors on the cables to the speakers and bananas plugged into the same binding posts for the cables to the sub.

It sounds great. Are the cables the same AWG? Or shall I use thiner cable for the sub?

According to the tech at HSU I talked with there is no reason to use the same gauge cable for the sub since all it is carrying to the sub is the frequency and amplitude information which the sub then amplifies on its own. He said, essentially, that using larger grade cable was a waste of money.

I used Canare 48s, I think, which was overkill, but I had bought a bulk lot of it from Markertek for another project and had it lying around. I've also used cables made from Cat5 network wiring, also because I had a spool of it, and it worked fine.

thanks for the input; I really appreciate it!

Hi, original poster here.
Is it possible to use the same SW for an HT system and a separate audio system?

Still have the ARC gear for audio and was thinking of using the same SW for the HT. Is it possible to connect a single SW RCA cable to my HT and continue using the dual wire method for the ARC amp/pre? The SW supports both single RCA input and dual speaker wire inputs.
Of course not having both systems on at the same time.

Thanks
