Assuming the use of similar wires from the same product line can using a gauge or two larger than what's actually required be detrimental?

The size of this new room would dictate a minimum 16 gauge wire,I only own 12 gauge and if could find it I would consider an in wall 10 gauge.

All things considered a 14 should be sufficient.

Anyone ever A/B/C...a size to small/suggested/larger than required to see if going larger has any negative effects?

Going larger has no negative sonic effects with speaker cable. But the negative financial effect is a factor biggrin.gif.

Glimmie is right.  Bigger than needed is not harmful.  If you want to read more on this topic:

 

http://www.roger-russell.com/wire/wire.htm

 

If you do not want to have to change wires if you change to speakers with a lower impedance, going a bit big can be practical.  As noted at the link above, this is particularly relevant when installing wires in a wall, as changing them to something else would be troublesome.

 

With that in mind, I normally just buy 12 gauge these days.  But it is larger than it needs to be in all but one of my uses of it. I still have and use some 16 gauge wire, which is commonly large enough.


God willing, we will prevail in peace and freedom from fear and in true health through the purity and essence of our natural fluids. God bless you all.

You can get 14 gauge pure copper speaker wire from Monoprice quite inexpensively, and that is large enough for all but amplifiers over 200 watts or wire runs over 30 feet.

One thing to be careful of, however, is the crappy copper-plated wire that is sold in some places.

You want wire that is 100% pure copper.

100 feet of Monoprice #14 speaker wire is $25; Monoprice Stock #2791.

For in-wall, use #2820, which is jacketed; about the same price.

600 watts (potential) to 4ohm speakers (average) over 50' = 10 guage?

And potential connectivity to terminals, strain from the weight, routing/hiding thicker cable, etc.

Just because there is a knob doesn't mean you should turn it.

10 gauge would result in a 1% loss in volume over 50 feet on transient peaks of maximum power.

With 12 gauge it would be perhaps 2%.

Do you really think you can tell the difference between 99% and 98% volume?

ROFL!

That's 12 amps of current at 50 volts. That's getting into a gray area over 50 feet. Is this a PA or concert setup? Because that's a lot of power for a home system.

12 gauge it is...
This is for my new screen room/cubicle.
Thanks guys, I just needed to confirm no negative side effects.

I read the points made in the link you posted and it suggested the 10 gauge at 50' if the speaker impedance dip below 4 ohm's.

Thank for posting the link.
