This was my first active setup and I was just going to let someone else tune it but it sounded good to me flat so I just left it.

Also, here is how they are mounted. They appear very clean with no water damage or surface rust or anything. Iím not seeing weather damage anywhere unless just the drastic temp differences just make the surrounds brittle over time. It does take like a year typically for them to go out.
Default slope is 0db an no crossover on my pioneer da-230, if yours is the same that could well be your issue, but double check and set them to 24db/octave for subs and your mids 👍🏼
