Maximum volume is a different matter. Maximum volume depends on the maximum amount of air a speaker can move. That is dependent on the cone area multiplied by the cone excursion. 18" drivers tend to have a larger cone excursion (Xmax) than 10" drivers do. Looking at a few Eminence spec sheets, I found 10" drivers with Xmax of 3 to 3.5 mm, while 18" drivers had 8 to 10 mm. so, while four 10"s have a greater area, a single 18" has much more swept volume, and can move more air, giving it a higher maximum volume. How important that is depends on which is reaching its limit first, your amp or your speaker.

That's a good point. Most 1x18s are not designed to be used by themselves. Most 4x10's are.
many 4x10" cabinets have an added tweeter to extend the high end. No reason an 18" can't have that as well. Most 1x18" cabinets don't, though, because they're usually used as woofers in a system rather than as a stand alone cabinet.

No. The Xmax of the drivers doesn't add together. Each driver can still move only 3-3.5mm. Having four of them will move four times as much air as one would, not 16 times as much.
Wouldn't that make your 410 cabinet have an Xmax total of 12 to 14? :idk:

Would 2-12s be an option worth considering? Why yes it would.Although I am still tickled pink with my GK 4/10 neo!
