Rel t9x or Rythmik F12G

Small room. I’d go with a pair of REL T5x. I have REL S3 and love them. Even though the 5x are small, they work well in a small room. You don’t want to overpower the space.

Complete no-brainer... Get the Rythmik F12G and call the trash guys for Rel disposal.

+1 for a pair of REL T5x.

I have a pair for my little AR M1 speakers, but I also use them when I’m using a set of Tekton Pendragon in my 12 x 18 room. Easier to set up to blend with the mains when you use two subs.

If you listen to a lot organ music then maybe get the Rythmik :)

I’ve had both and would go with Rythmik.  I’ve had many REL subs over the years and enjoyed all of them except the T9x.  I had a pair and just could not get them to sound good.  The Rythmik goes a lot lower also.  My experience with the T9s made me question their quality and price to performance ratio.  They market their new aluminum drivers as an upgrade but I think their old doped paper/pulp ones are better.  At around $1100 shipped the Rythmik are a tremendous value.
