The Imperia is the ultimate speaker from OMA.
Four years in the making, the Imperia is a four way horn system, with a vertical array of conical horns covering 100hz to 20khz, and a rear loaded subwoofer horn using a massive 21" neodymium woofer handling 20hz-100hz. This special OMA sub is 104db 1w/1m and is powered by its own solid state amplifier. The system as a whole is extremely efficient at 105db 1w/1m, and is entirely time aligned.
The 100hz and 300hz wooden conical horns are made from a choice of solid Pennsylvania Black Walnut, Cherry or Ash. The 300hz midrange horn uses the incomparable Cogent DS1428 field coil compression driver. The high frequency horn is cast by OMA from aluminum alloy. Outboard crossover network is coupled to the Imperia via a solid slate patchboard.
Simply put, there is no speaker system in the world today like the Imperia.
