its all about displacement

A smaller diameter cone makes for less chance of cone flex or uneven weight,

Cone flex will be minimal either way. If we were talking about midrange speakers...sure, could create problems. For subbass? Non-issue for the most part on any quality sub. It's effects will be far less drastic. And uneven weight should pretty much be a non-issue.

On top of that, an 18 would need a 4.5" voice coil to scale with a 10" cone and a 2.5" voice coil.

"Scale" how?

Not to mention a longer/larger surround, bigger spider, and larger basket, all of which pose the risk of being made off center.

That's only a hypothetical......Not to mention, if something is off-center enough to cause a drastic change in performance, then that falls under warranty work for error in craftsmanship.

lol please explain more, I'd like to hear this. //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

If you want to talk stress, an 18 wouldn't have to work nearly as hard (as much excursion) as that 10 to produce the same output, therefore less stress on the cone/suspension/etc.

And to add to that; Since the coil isn't traveling as far, the motor would be more linear //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
