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.

The 18" Impero 18A is rated at 1,200 watt continuous / 2,400 watt program power, has a frequency range of 39 Hz to 820 Hz, and is suited for full-range three-way boxes, bass guitar boxes, and small subwoofers. This model is also available in a 4 ohm version, the Impero 18C.
