I'd love to hear a pair to compare to my 2.3tls
Many here opine the 2.3TL represents the best of the last generation of the SDA SRS. I have not heard a TL pair yet. The RDO-198 tweeter is superior to the 194. -

A friend of mine who I sold my modded 2.3's to picked up a pair of the 2.3TL's. I rebuilt his crossovers for him but haven't had a chance yet to go over and compare. I'm curious myself.Gustard X26 Pro DAC

I sold the very same pair a couple of months ago for $150. Perhaps because I didn't have the requisite gear. :'(

We can either blame inflation or his highfalutin' gear..
Of course, he's got all of that gear and doesn't have the SDAs setup properly...KEF Xq5s / Velodyne DD12 / Apollon Purifi 1ET6525SA / SST Thoebe II / Bluesound Node 130 / Oppo BDP-105D / Technics SP-15 w/SAEC WE-308SX & Ortofon AS-309 arms / Audio-Technica ART-1 & Dynavector XX2 Mk II carts -

These are the SDA 2s I had. They were great speakers, but the side panels warped and wouldn’t flatten out to stay on. I was a bit P.O. about that.

Polk SDA SRSs with RD-0194s for...drum roll please...$30. VERY Briefly...
https://www.ebay.com/itm/Polk-Audio-SDA-SRS-Floorstanding-Speakers-Good-Condition-EXCEPT-interconnect-/114575734392?hash=item1aad3ef678:g:4UAAAOSwtFVfQpZc&nma=true&si=f4tlPlWbjMranubKjCo%2BCifRzQI%3D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557
A while back I had been in contact with this guy about these speakers. We figured out that some years ago, he had replaced the SL-2000s with RD-0194s.
After I asked him about the XLR and standard SDA connections, he realized he hadn't ever heard them with the SDA interconnect properly connected. So, he went off and tried to connect them to hear the SDA effect and I figured that was the end of the story.
Apparently, he heard no difference when the SDA cable was connected, so he took them to George Meyer AV in LA to get them fixed. They said it would cost between $1300-1500 PER speaker to get them back to the way they left the factory.
Based on that, today he offered them to me for FREE. Of course, since I'm NOT in LA, shipping would have been $$$ and I recently bought another pair. So, I told him that there is no way that fixing the crossovers could possibly cost that much and referred him to Westmassguy.
I don't know if there are other problems that I'm unaware of, but it looks like he also put them on ebay for a whopping $30 and they are already sold.
I wonder what is going on inside those speakers...KEF Xq5s / Velodyne DD12 / Apollon Purifi 1ET6525SA / SST Thoebe II / Bluesound Node 130 / Oppo BDP-105D / Technics SP-15 w/SAEC WE-308SX & Ortofon AS-309 arms / Audio-Technica ART-1 & Dynavector XX2 Mk II carts
