The sound field produced by loudspeakers at low frequencies in small- and medium-size rectangular listening rooms is highly nonuniform due to the multiple reflections and diffractions of sound on the walls and different objects in the room. A new method, called controlled acoustic bass system (CABS), is introduced. The system utilizes front loudspeakers and extra loudspeakers on the opposite wall of the room processed to cancel out the rear-wall reflections, which effectively conveys a more uniform sound field. The system works in the time domain and presents good performance over the loudspeaker low-frequency range. CABS has been simulated and measured in two different standard listening rooms with satisfactory results.
