Eminence Impero 12A 12" 1100W 8 Ohm Loudspeaker Driver

PRICE MATCH AVAILABLE!

Eminence is proud to introduce three advanced high-power additions to their Professional Series: the Impero 12", 15", and 18". Italian for "empire", Impero sets the tone for this elite offering of high quality, hand-built loudspeakers.

Using high motor strength with balanced Vas and Mms, the Impero series plays extremely loud and low in compact vented designs. Advancements include a 1/2" thick by 7.5" diameter machined top plate, one piece machined T-yoke, and a 4" deep wound fiberglass voice coil. These features combined with an ultra-linear long-excursion suspension and bumped motor assembly allow the Impero series to move serious air, generate serious SPL, while handling tremendous amounts of power.

At 1,100 watts continuous / 2,200 watts program power, the 12" Impero 12 has a usable frequency range of 56 Hz to 3 kHz, making it perfect for two-way top boxes, full-range two-way boxes, bass guitar boxes, and high-powered small subwoofers.
