Internal Speaker Cabling

Absolutely. I am presently getting my KEF 104/2 upgraded; silver/copper MIL spec garde wire from a U.K. source for the mids/high and heavier gauge pure copper wire for the twin woofers. This company in Montreal called FixAudio are doing the work for me. He refurbished a pair of KEF 105's of his and boy what a significant improvement! I am also upgrading the caps and some resistors.

I have two sets of speakers, one is internaly wired with DH Labs Silver Sonic cable and the other uses Tara Labs RSC. I also have an inexpensive pair of Acoustic Energy speakers that I put in Canare cable. It makes little sense to run 10 or 12 gauge cables into speakers with 16 or 18 gauge internal cables.
The same thing can exist in amps where 18 or 16 gauge wire is used to connect output section to speaker connectors. Changing these wires is a great DIY project.

Well I think Thiel uses straightwire, Eggleston Works uses transparant. I think most use quality wire...what we buy on the open market is aimed at a target audience of audio and videophiles. If there wasn't a need/market we wouldn't have the equivilent of a small mortgage in wire, IMHO.

Here's a good one to ponder...

What to do about the 130 feet of fine wire in your tweeter, midrange and woofer coils!!

And you were worried about a few feet between the drivers??

YIKES!!!!

Looking in the Musicdirect catalog I recieved today I found and add for 6' speaker cables for $8900 , and a pair of interconnects for $3995 , well known brands. I'm sure there are more expensive examples.
You have a very good point. Let's say it cost the manufacturer $40 per speaker for internal wireing. Then you buy $2000 speaker cables?
It would be good to know you have high quality cables. My personal opinion is that successful high end cable manufacturers laugh all the way to the bank everytime they sell a pair.
Now I'm thinking I need to take a look inside my speakers..
