Crossover and Wiring Upgrade

Hello. Not sure which speakers you have but share my personal experience. I have a pair of JBL L100T's purchased new in '87. They were always just a tad bright on the high's but certainly listenable. Noticed this guy on eBay called the crossover chef , he makes upgraded crossovers for about 40 different speakers including all the vintage JBL's @ about $400 delivered. His ad lets you know it's a 3-4 month wait so that says something. I sprung , they arrived almost 4 mo later and are twice the size of the originals. Had a hi-fi guy help me install them and wow I now have different speakers quite an improvement. The high's are smoother , as is the midrange and more low bass without being muddy. Best $400 I ever spent.

What is it about the speakers that you don't like that you are trying to improve?

If you intend to open up the crossovers to rewire them, you will get FAR MORE "difference" by changing the value an internal resistor or capacitor by even just a small amount while you are in there.

Remember that "factory-built" speakers are auditioned in an entirely different setting than your room, and a bit of crossover tweaking may pay off in spades..., if you know what you are doing.

Cardas solder excellent sound and has flux rosin built in flows nice , Donot use a solder pen spend $100+ on a good-solder station 

+1 on both counts. Cardas solder is actually quite good, albeit not inexpensive (the cheapest source as of this writing is the diyaudio store). Flows well, low melting point, it's a treat to use. Honestly it's not a lot better than the Delta 62/36/2 I used to use, but the Delta isn't that much cheaper either. 

I have a 200W AiXun T3A soldering station I really like, it was like $100 including a selection of C245 active tips. Recommended

@pindac - WOW, and YOU want ME to take anger management?! Just take a long look at the diatribe you've posted! I think you're on the wrong forum.

I believe you need some professional help pindac - get some therapy, as you obviously have mental health issues!

Just because you believe it doesn't make it true. None of what you're suggesting will make them sound better. You just need to get different speakers. Different sounding cables/wires? Come on, man. Don't be willfully ignorant.
