Hi,
I had the opportunity to purchase L300. the internal cables have been completly replaced by.... I imagine, supposedly "better" cables ....
What do you think ? does it affect the overall result ? does it improves it ?

Its relative to the rest of your system...?
I have made some cables using Cat 9 and using individual insulated strands made a cable similar to Kimber design and used bi wiring from the crossover network all the way back to the amp for the woofer / mids and highs.
Another option is to loom the strands around a narrow hollow core of dielectric.
I can vouch that on a reference system (Lavy Dac and Pass labs amplifiers) the bass , mid range and highs took on a more life like quality in that separate notes could be more easily delineated.
Get rid of the old crappy JBL connectors and put in some new binding posts that have at least gold plating.
The binding posts on the stock JBL 4345 crossover network were steel or an alloy akin to a roofing nail so I replaced them!
The terminals on most JBL drivers are of similar construction!
I regard terminations as more important than wire as dirty or poor conductors do not pass electrons efficiently.
In that respect keep your wiring short.
Also have a look at the Nelson Pass crossover upgrade

+1
Terminals have been changed aswell.... (see pic) I was assuming that there is no "good cables in themselves" but "good in a system".... that is to say if the overall tend to be bright adding new cables can shift the averall sound to even brighter.... as in two much.... for instance...
With these particular JBLs the integration of the woofer and horn is sub optimal in that the dispersion of the woofer and the horn is dis continuous and there are significant response irregularities in the vicinity of the crossover point.
The effect is that the horn can sound well like a horn on certain kinds of music.
These speakers sound good on rock and roll but are not accurate on classical music.
So within the constraints of the design don't expect to make a silk purse out of a sours ear by thinking that cable or other upgrades will work wonders.
It won't but you will have fun trying!
In the interest of being argumentative:
Gold is not that great of a conductor. What it does more than anything is bump the price of connectors that are plated with it. It's actually easier to get a poor connect with gold than with several other metals. What gold DOES offer is the absence of corrosion or patina developing over time. Plain old nickel is a better conductor, (even silver if you want to go nuts). Brushed nickel connectors offer a good solid connect, don't corrode and cost less. Even cheap chrome on steel will give you as good a connection as gold.
But I agree completely that connects are more important than wire, and that JBL has used some pretty poor connects over the years.
Oh, like the lowest bidder, afterthought ones up till the 80's ??
The infamous spring loaded push types that couldn't take more than 20 ga. wire ?
or the "improved" twist-lock (twist & break) from many of the "A" variations that
were also limited to small ga. wire ? Or even the modern-ish knurled knob , long shaft
specials ? Or even the more modernish 5 ways on my 250Ti's that have trouble taking 12 ga. , so that I have to use banana plugs ?
Even with all the past junk connectors/internal wires and the speakers still sounded fine.
Some kind of happiness is measured out in miles
