Interesting way to wire speakers…???

It takes good copper quite some time to corrode enough to degrade sound, given a nice, tight crimp. The process can even be slowed further, by the use of a contact enhancer(ie: (https://walkeraudio.com/shop/e-sst-sst-extreme-super-silver-treatment-for-contacts/) or (http://www.vhaudio.com/contacttreatment.html) If the OP's point is better sound; his goal would be better served by the use of straight copper or(better yet silver) jumpers, cleaned with rubbing alcohol or a Caig's product, every few months, before corrosion sets in: (http://www.whatsbestforum.com/showthread.php?1652-Contact-Cleaning-The-Right-Stuff)

If jumpers are used, then use bare wire not terminations. All spades,
bananas, posts etc... Degrade sound no matter the cost. Better off wiring as
the posters picture shows IMHO. Cleaning the wire regularly is also a good
idea. I don't use any posts or spades etc.., but simply use binding posts
to clamp the wires from my outboard crossover to the speaker cable. Nice
jump in sound quality. I found a very thin layer of WBT solder on the tips of
the exposed wire terminations works great.

The simple solution is to strip away the plastic coating only where it makes contact with the binding posts.

Or cover the bare wires with some Teflon tape or reapply the plastic sheath to cover the exposed wire.

This isn't a bad way to keep the system tuned to the sound of that single type of wire.

I hate what those speaker brass jumpers do,better to make your own with the same speaker wire.Jumpers add spades or banana connectors,hole in binding post may not be large enough for two wires.

Or you could open up the box and attach the internal wires to one pair of binding posts.I did that with a pair of Mirage M3si and enjoyed the sound of my single run of costly speaker wires.

shhhh...the jumper cable salesmen are not going to want this secret out!

I have done the same thing with my Mapleshade Double Helix cables after struggling for a long time on what to do for jumpers. Made the most sense to me to have matching cable but maybe there is some weird physics going on with this setup, who knows!

do it, I like the idea!... but the bottom binding posts will squish the wire and the electric juice won't flow to the top binding post or only some of it will and voices will sound choked.
and..Exposing bare copper wire like that may cause a homeless person to break into your house and steal your cables
