Low-frequency Polar Pattern Control for Improved In-room Response
A loudspeaker arrangement, consisting of two individual drivers and delay units, having omnidirectional polar pattern at low frequencies and first-order gradient pattern at middle frequencies is presented. This system combines the low-frequency dynamic range of conventional speakers with the ability of gradient speakers to reduce roominduced coloration. The benefits and limitations of mid-frequency directivity are analyzed through simulations of room-speaker interaction for omnidirectional, cardioid, and dipole loudspeakers.
