The low-frequency performance of loudspeakers is essential to the listener preference rating. To achieve the same low-frequency performance as conventional speakers, an optimized construction of a woofer-driven flat-panel loudspeaker was designed. The woofer radiates in a small air gap between the panel and the distance plate and excites the panel uniformly. At low frequencies, significant improvements compared to an exciter and a comparable performance to a conventional woofer system could be reached. This paper presents a numerical system analysis of the paneled woofer design, which provides a detailed understanding of the system’s behavior. Furthermore, the radiation mechanism is compared to that of an exciter. All simulation models are comprehensively validated with the corresponding experimental data.
