I’m considering upgrading my speakers internal wiring

@bobbyloans If it ain't broke don't fix it.......unless you are an audiophile...you know you want to noodle around. Why not. @waytoomuchstuff makes excellent points in the how to department. But before you get to your workbench is your room treated?

Second guessing oneself is par for the course. You may also need to see the voodoo priest Xanthos Terwilliker to cast a spell eliminating confirmation bias of your hometown pride in your modifications.

IMHO, internal wiring does not do all the much, that being said, I have never used any exotic wire, just OFC copper. Unless I'm putting in a new XO, usually just keep the OEM wire.

Also from experience, take a picture of all the connectors before you remove any of them. If any of the terminals are not marked +/- mark them before removing anything!!!!! Nothing is worse than spending hours swapping parts out, only to have something out of phase. It will never sound good, and you will curse yourself chasing it down. Woofers are usually easy, mids/highs can be tough to tell phase. 

Crossovers will yield huge benefits! However, it will also cost a lot to do correctly. Spending $20 on a single resistor, or over $100 on one cap. Just know, for a 3 way, simple XO it can be $500 in parts.

Don't forget the binding post, this is another area where most manufactures cut corners. Even speakers that cost $10k can have $10 binding post in them. Take a magnet to them, if it sticks, you want new post.

Good research, and comments.  Well done.

@ghdprentice Thank you,

@bobbyloans  -  After reading through the posts, it got me thinking.  So, something to consider, or not....  If you are looking to dive in and tinker, learn what things can improve SQ, or just change it, rather than experiment on your $$ main speakers, maybe purchase some inexpensive speakers (inexpensive being relative) and play around with them instead.  Especially if you get something that was more mass market with more "compromises" that you can "correct".  Hey, and maybe acquire 2 pair so you have a baseline to reference.  LOL  

That might be fun.

I like the make the internal connections better if possible idea more.  That can only help and not hurt if done right.

Also I would add that tinkering with a product often leads to less interest and value on the resale market if properly disclosed because now the product is not what the original vendor sold, but something some guy decided to experiment with.  

Ultimately, the decision to tweak or not is yours. It will be an experiment with unknown results until you try. Is that OK with you?
