Are there any sonic differences between the two? What IS the difference between the two? Everything I have is 8ohm and so has everything I've ever owned, to my knowledge. I'm looking into getting a matching Orange cab for my Tiny Terror, Orange makes the cab in 16ohm only, the TT has a 16ohm jack so it's not an issue, I'm more curious than anything.
I believe the voice coil is longer. More turns of wire. I've never been able to tell any difference.
The actual coil of wire itself is longer and made of thinner wire in most cases.
It's useful to recall that impedance is the product of two separate things: resistance, which is the same for DC and AC current, and reactance, which is purely an AC phenomenon.
A change of impedance from 8 Ohm to 16 Ohm produces a change in reactance as well as resistance.
Consider the case of a Creamback Celestion. The 8 Ohm version has a DC resistance of 6.7 Ohms. The 16 Ohm version has a DC resistance of 13.1 Ohms.
Now, why is one speaker's DC resistance 1.3 Ohms from it's nominal impedance while the other is more than double that distance from its nominal impedance?
REACTANCE. This is the change resistance to current caused by the magnetic field that surrounds the current that flows.
The "motor" on an 8 Ohm and 16 Ohm speaker are electromagnetically different. They have different resonances and different efficiencies. 16 Ohm speakers are usually a little brighter and a little louder, from what I can tell.

GuitarZ: Argghh! ETA for power is Sunday midnight. Thank you for giving us all a place to vent. At least we have a generator and our house suffered zero damage from the storms.

Ed M.: Yup generator is humming along.....

GuitarZ: Yea! Our power's back on. They beat their estimate by two days! Yea!!!!!! Let's hope you're right behind Ed M.
