No kidding there would, if the 22ga wire was longer than a foot or so.
Its comparatively high resistance forms a voltage divider with the
speaker's load impedance. Since the latter is usually far from flat,
you get a built-in EQ curve following the shape of the speaker's
impedance. Not desirable.
22 gauge wire has a resistance of *16 ohms per thousand feet or 0.016 ohms
per foot. Rule of thumb is that a 1:50 voltage divider can be counted on to
produce no audible attenuation. *If the speaker involved has reasonable
worst case impedance curve variations and a rated impedance (i.e.,
approximate minimum impedance at any normal audio frequency) of 4 ohms, the
wire could be about 5 feet long with no audible effects. Or, if you will a
30 inch speaker cable.
Not too far off from my guesstimate of a foot. In any case, running 10
feet of 22ga speaker cable, or 20 feet, is definitely not recommended,
which was the point I was making.

Honestly... does "speaker wire" come in 22ga? or even 20ga?
Usually it's at least 16ga, often 14ga or 12ga.
