Eminence IMPERO 18A 18" High Power Driver Speaker 8 Ohm 1200W

The Eminence Impero 18A 18" high power pro audio speaker is optimized for use in vented enclosures. Its 1,200 watt continuous power rating is a result of Eminence's extensive experience designing and manufacturing loudspeaker drivers for serious professional use.

The Impero 18A's performance is ideal for full-range 3-way boxes, bass guitar boxes, and compact to medium-sized subwoofer speaker systems. Recommended enclosure volume: Vented: 113.2 ~ 277.5 liters / 4 ~ 9.8 cu. ft.
