I have assembled alot of Gr Research crossover upgrade kits for clients. I do assembly of the crossover but sometimes I have people sending me their speakers new or used to have the upgrade installed. In my opinion any upgrades you do to a speaker crossover to replace mediocre parts and change them to better ones
will be significant, the Re designs of the crossover I have heard especially in the Klipsch lines, Sony, Sonus Faber etc. Is a big improvement from stock. I know its hard to wrap your head around how parts quality changes and improves sonics but you really have to try in person to experience.
I have had the same experience even before moving here to the U.S. from Asia. Even my distributors there are always open to upgrading parts. I hope you have a fun journey🙂👍✌️. Thank you
