Speakers come in different wattages, different diameters, different voice coil diameters, different cone material, different surrounds, different magnets... you name it.
All else being the same... and I mean ALL else, just the diameter increase will give you more bottom _and_ the cone will break up later.
The cleanest speakers I've ever seen - full range for guitar - were the JBL D130-F
There are sleeper 10's out there with huge bottom - the old Celestion Vintage 10 (which I still have a few of).
The Eminence 10ALK was another (although lower wattage).
The biggest bottom speaker is the old Celestion H cone 12's, very clean too, late break up with a very stiff cone.
The Celestion Silver Series 12's were also sleepers. They're the "poor man" version of the Vintage 30, slightly wider coil gap, slightly tighter cone... very tight bottom, an excellent speaker, and rated at 60w each, like the Vintage 30 ( which in itself is great 60watt speaker).
