Question about thicker wire size for loudspeaker

Since the length of the internal wiring is so short, even thin wiring has negligible resistance to the flow of current.

As a consequence, I would expect no audible difference in replacing thin internal wire with thicker internal wire.

Of course, thicker wire may be gainfully employed between amp and speaker to compensate for the fact that resistance increases with length.

The voltage drop over distance usually amounts to fractions of a dB, not really audible.
The drop in damping factor from using thin wire over long runs makes more of a difference to sound quality.

As has already been mentioned, the effect of a short piece of wire inside the cabinet will be negligible, as long as it's connections are low resistance.

Hi all!
Refer to the attachment, which is about Cardas internal hook up wire suggestion for speaker. If 17.5 AWG for the midrange, what about treble and bass unit?

Thanks!

Some use high output impedance (very low damping factor) amplifiers where these things don't much matter. They have no complaints about quality, some note the improvement in distortion figures. The main difference is usually the response, which in either case is fixed by equalisation.

They suggest smaller wire for the tweeter, and larger wire for the woofer.
9 AWG for an internal hook up wire would be over the top (would not make an audible difference) even using a 2000 watt two ohm woofer.
 
What about 19.5 for tweeter, 17.5 for midrange and 11.5 for the bass?
Those gauges would work fine as long as all the connections are low resistance.
You could use any of those gauges for all the internal connections and still not hear the difference.
The speaker connections are often a higher resistance than a short piece of wire, and with oxidation, can increase to infinity- that's easy to hear ;)

Cardas is an "Audiophile" cable manufacturer so take that table with a big grain of salt.

As mentioned by others, 18AWG stranded wire is a good general purpose choice, and works everywhere.

18,5 AWG and similar sizes are NOT standard, NOT in the "official" SWG table, and look made up to "look special".
Of course, only "they" offer those weird sizes. 🙄

9AWG wire (8 mm diameter) is nonsense inside a home/HiFi speaker cabinet.
