Just a side note on building your own crossovers with upgraded parts.
I built new crossovers for my Klipsch RF83, new upgraded parts with same values, from GR Research, and I could not believe the difference that made. My speakers were practically transformed for the better. Not only to my ears, but the measurements proved what I was hearing. This motivated me to continue with bracing the cabinets, changing internal wiring, just ordered NoRez for internal damping and ordering pure copper binding post, and I am sure this will contribute even more. The sum of all these parts should make a considerable difference for the better, I hope!!
I can't stress enough the impact of upgraded parts for your speakers. It is an affordable difference that could have a huge impact. Try it, you won't regret it. And if you can't hear a difference, at least you learned how to build crossovers and got the doubt out of your system!!
