A speaker system that's fed by two separate signals. One signal contains all of the low-frequency material (feeds the woofer), the other signal contains all of the high-frequency material (feeds the horn). An active crossover is used to split a full-spectrum audio signal into the two parts, then separate amplifiers are used to power the woofer (low) and the horn (high).
