In my experience, they're not awful, but they're certainly not great, either.
I wouldn't -- and didn't -- waste my time on a pair that passed through my basement some years back.
That said, adding some stuffing, bracing and replacing the (most likely) two NP electrolytics that make up the crossover with a couple of decent capacitors would likely improve their sound. Whether it's worth the effort in any way, shape, or form is debatable (but testable), I'd opine.
I wouldn't recommend going any farther than that with 'em, for the enclosures themselves are pretty nominal; not a good platform for a true makeover (again, strictly my opinion).

I gave mine to someone... but at this late date I don't remember to whom

In true AK fashion, sell or donate. You've stated you have better sounding speakers, and based on the "tone" (so to speak) of your initial post it likely would not amount to a equal return on investment (ROI). Or put another way, you may not get out of them what you ultimately will have invested. That would prove a bigger setback AND you likely would not recoup your investment.
Someone out there WILL appreciate them as their are always people out there starting out who are still in the White Van phase, or inherited some "Big Box Store" component system.
Wouldn't mind having that KA-7100, nice amp. Had a KA-3500, and miss it.
yes, this ka-7100 is a long story... about the ns-a, my starting idea was not to built a pair of speakers that will be my best but, i like the small design of them. my other boxes are most floorstanding type so...maybe should be best to work on my bose 301? i know they are better quality than the ns-a but i always dislike the ported design. all my sets of speakers are closed box.
