Eminence Impero 15A 15" 1200W 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.

The 15" Impero 15A is suited for two-way top boxes, full-range two-way and three-way boxes, bass guitar boxes, and small subwoofers, and is rated at 1,200 watt continuous / 2,400 watt program. With a frequency range of 46 Hz to 2 kHz, this 15" has the extension at both ends to go low and high, perfect for small vented boxes with conventional sized horns. This model is also available in a 4 ohm version, the Impero 15C.
