Greetings, first post. Sorry if this is redundant but can't seem to search for "L36" on this forum

Anyways, picked up these speakers for cheap, they sound good. Wood is immaculate. One of the woofers is rattling and the tweeters are pushed in though.

So is it worth it to replace the drivers and/or crossover on this speaker for an improvement in sound quality? Or would I be better off upgrading to one of the higher L1XX models? Thanks!
