It might be a good idea to listen to them for awhile first. Get a feel for what they sound like in your room. Placement / position is the key.
I’ve sent my plates to the factory and had them do the hot rod and pretty much everything they offer, plus a couple of my own mods. Silver WBT posts etc..
Did it do anything? Idk… it’s fun to mod, but I don’t really think the money I spent was a night/day improvement.
These speakers are built pretty much at the peak of their performance imo. Make sure you have plenty of good power to run them. And I can’t stress enough proper placement and getting them dialed in.
