Eminence IMPERO 12A 12" High Power Driver Speaker 8 Ohm 1100W

The Eminence Impero 12A 12" high power pro audio speaker is optimized for use in vented enclosures. Its 1,100 watt continuous power rating is a result of Eminence's extensive experience designing and manufacturing loudspeaker drivers for serious professional use.

The Impero 12A's performance is ideal for full-range 2-way top boxes, 2-way boxes over subs, bass guitar boxes, and compact subwoofer speaker systems. Recommended enclosure volume: Vented: 33.98 ~ 118.9 liters / 1.2 ~ 4.2 cu. ft.

4 ohms available?

Asked by: Fergie
Eminence does not offer a 4 ohm version of this speaker. There is a 4 ohm "C" versions of their 15" and 18" models which would be the IMPERO 15C and IMPERO 18C respectively.
