Hello,
I would get the matching older sub for right now. Everyone says get two matching subs. If you buy the matching sub to your current sub you will have a pair. This should make them both more valuable. I have a pair of the T9’s. I love them. The i or x models are front firing and the older version like mine are down firing with a passive front woofer. I agree if you are buying new subs get the S series for music. I use a home theater pass through on my system. I like that the Rel subs have Speakon and RCA for music and LFE RCA for the movies all separately adjustable. They go down to 28hz so I might add a KEF KF92 sub just for the theater side to go down to 11hz. We will see. Grab the matching sub to yours for now. Wait for a deal on the new REL stuff.
