AB  - Recently, there has been a strong interest in the development of flat-panel loudspeakers. The Yamaha JA4001 and the Poly-planar P20 represent two early attempts at commercializing the technology. The responses of both loudspeakers were analyzed using a laser vibrometer. The scans for each panel depict sharp peaks in the frequency response, which correspond to resonant modes. The presence of additional modes is similar to the effect of cone breakup in traditional loudspeakers. Impulse response measurements show that low-frequency modes are highly reverberant. Studying these early planar loudspeakers can provide valuable insight for the further development of such technology.
