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.

https://www.hifiplus.com/articles/rel-r-328-subwoofer/

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 have both a G2 and a Stadium lll and each has attributes that are unique to each. The G2 is fast enough to keep up with the 6 servo controlled woofers in my Genesis G500 speakers but I had trouble blending it with other speakers. The Stadium lll on the other hand has extension that provides a different acoustic signature and its speed blends better with most speakers. Think of the G series as a Porsche and the ST series as a Cadillac. The Stadium lll provides solidity and air and the G2 adds speed and definition.

Hope that helps

@wolf_garcia,

The only issue I've had with my REL subs is the surround coming loose from the frame on my G2 but some heat/pressure reattached it with no issues. Of course, this driver really has some extreme excursions when played aggressively as I'm known to do from time to time!

The best upgrade one can do for an older ST series REL is to replace the rail caps with Mundorf caps and double up the resistance wattage capacity on R7 resistor which is a known failure point on older REL's.

My apologies to everyone, it is R8 that is the resistor that is the known failure point on older REL’s.

@noromance,

I agree. R8 was under speced and sticking it inside a cabinet with no air flow ensured its demise. Most failures of the ST series were solely because of R8.  
More to discover
