You have not mentioned associated system components, available amplifier power, room size, desired spl range or price range, but if we take your interest in the AN 12 inch dual cone as an indication then consider the following alternatives:

EV LS-12
EV SP-12B
Altec 419-8B Biflex
Eminence Beta 12LTA
JBL D-123

Of these, only the Eminence is currently produced. The others are 'vintage' drivers that are commonly available on eBay at close to the price for a pair of the AN's. All of the 12 inch 'full range' drivers have compromises or flaws that must be lived with. None are perfect, but all deliver a remarkable sense of coherence, have unusually good clarity and dynamics, and are easy to drive with low power tube amps w/o negative feedback. The Phy 12 inch full range drivers are about as close to perfect as 12 inch full rangers get, and their price (see Madisound) reflects this.

You have not said why you want to go with a 12 inch. Not that the 12 inch drivers are less desirable or poorer performers, but there are a great many smaller full range drivers that could potentially meet your needs. If you want substantial bass output then consider a pair of the smaller full range drivers and add a sub. Very cost and space efficient.
