Polk Audio SDA SRS 2.3 - Crossover Replacements?

Hi guys! I have a set of original SDA SRS 2.3(tl?) here, that my father gave me. They're original stock. I'm wondering if they may need a crossover replacement. The bass response is poor in a specific frequency range - it takes a significant EQ boost below 50hz or so in order to sound correct. Once boosted, though, they sound fantastic.
So, just a couple of questions I'm hoping you can give me thoughts on:
1) Are these 2.3 or 2.3Tl? There's no labels or anything obvious, though I haven't taken them apart to see if there's any interesting labels inside.
2) Would a crossover upgrade fix this problem and generally improve evenness of frequency response?
2b) I'm well versed in digital circuitry, but analog stuff (like audio!) I'm terrible at. I can solder things just fine, but I'd love to buy a pre-assembled replacement crossover that would be suitable (if answer to (2) is yes). Is there such a place I could buy something, or is there someone that custom makes them? What kind of price range would I be looking at?
3) Any other general thoughts on keeping a 35-year-old pair of speakers running well? They're in gorgeous shape, my father was the original owner.
PS. Did y'all see that the SDA line was reintroduced? L800, $3000. If these speakers of mine didn't have so much sentimental value I'd give them a try!
Thanks in advance for any thoughts and suggestions. Cheers!

Yes, a crossover upgrade can dramatically improve your speakers, along with other upgrades such as new binding posts, upgraded internal wiring, modified internal damping etc. One option would be to contact westmassguy on this forum (DHS Speaker Service). He rebuilt the crossovers on my vintage Polks (1980 RTA-12's) and can walk you through the various capacitor options and other modifications/upgrades. He does very careful and meticulous work.

In addition, you have the left and right speakers reversed.
FYI, the L800 speakers are $6,000.00 for the pair. -

There’s older SDA’s?????
Taken from a recent Audioholics reply regarding "Club Polk" and Polk speakers:
"I'm yet to hear a Polk speaker that merits more than a sentence and 60 seconds discussion."![:\](https://forum.polkaudio.com/resources/emoji/confused.png ":\")
My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

The irony being that vintage parts will be available long after the L800 parts are no linger available- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.
