does 4-ohms sound better than 2-ohms

I've heard that although 2-ohms allows more power out of your amp but there is a difference in sound quality and a voltage drop.

so 2 no's and 1 yes

No

I'll agree and disagree.

In terms of the speaker itself... No.

But as far as the amp/power source goes, that's a different story. Most amps, as the resistance goes down, THD and S/N Ratio goes up. (Making the signal to the driver more distorted, thus sound is poorer.)

And, as resistance goes down, efficiency goes down (again, in terms of the amp/power source.) So, the amp pulls in a greater current to maintain the RMS it's set to.

is it really noticable??

As far as THD+N/SNR goes, no.

Depending on the amp's topology, the drop in efficiency can become extreme if you're talking about extremely low impedances (such as a half or quarter-ohm load), but generally, I wouldn't worry about it.
