A pic of the crossover and inside of cabinet would be helpful here. If they are updated properly and the drivers are in good condition, stay with them. I have a set of modern "towers" from a well known company. They retail for two thousand some a pair and are rated/reviewed as a great buy for the price. And of course their description on the website describe them as using top notch quality parts. Not so. Piano gloss finish and all but once I looked inside I was very disappointed.
The electronics are basic, made overseas(not always a bad thing.) Cost cutting by the speaker company for sure. Only one small poly cap for the tweeter circuit and small steel core inductors. Binding post is junk. Not enough dampening of the cabinet. The drivers seem OK though.
I revamped the crossovers with Clarity Caps and audio grade(?) electrolytic caps where needed. The tweeter/mid circuit inductors are now good air core ribbon style. Installed quality binding posts and added more internal dampening.
The result is worth the $$$ and time spent. Now, they not only look real pretty😉 but sound much better(at least to me).
