Connecting monoblock tube amps to single subwoofer.

The answer to the question is to add a second REL T5x to the system. This way, each sub can run off the particular mono block. This is REL's advice and it is well given. The addition of a second sub to my system is a nice benefit when it comes to overall bottom end resolution. 

One thing to consider, the addition of a second sub is exponentially harder to set up, with the blend and the correct positioning than just one sub. Given enough tweaking it works out well, but time and patience will be required to make it work.

What we are talking about is two REL T5x’s. They do have a phase adjustment switch and adjustable xover settings. Nonetheless, I think you are agreeing with me that the set up is not easy. I am no fan of digital room correction tools, much prefer to just use my ears.

@ieales   I guess that depends on how you want a pairing to sound, if you just plop them down anywhere, yeah you are right... no problem. ( Nope). OTOH, IF you want an invisible blend with your mains...then yup! 🤔
