Older vs. newer REL subs


Looking for any reports about older vs. newer REL subs.

I have a REL 328 (ca. 2013) which I bought used. It's a good sub.

I would like to upgrade to stereo subs and I've found (finally) another REL 328 which would match mine. But, before I drop coin on that, I'm wondering if anyone has had experience comparing their older REL with a newer one. What's changed? What's better, worse, or the same? I'm considering the T7x and T9x lines.

Hoping for apples to apples comparisons, vis a vis driver size, type of sub (e.g. level of product line, sealed vs. ported, music vs. HT etc.) but whatever old vs. newer comparison you have much appreciated. 

Thanks.

I work for an REL dealer and we have been bombarded with propaganda from them explaining the new T/x model's design evolution. Nothing would lead me to conclude amg56 is correct about their being targeted at HT.  They make HT-centric models.  These are music focused as are all their subs (except the HTs, which aren’t bad for music btw), with light cones for speed, and their secret sauce crossover and speaker level input.  The amp is unchanged. The x has a slightly larger cabinet volume and optimized driver and passive radiator compared to the i version.  Not night and day...incrementally better.  Still a fine value and product.
