AB  - After the successful introduction of the flat television, acousticians are concerned with the design of a “full-range” flat panel loudspeaker. New design with low manufactured depth, consisting of an array of two conventional cone drivers and a transmission line and the method for driving of them is presented. Main aim was to build a small sized flat panel box but with extended low frequency response and low distortion output because of the extended liner diaphragm excursion. The PSpice-OrCAD® simulator was used to represent a distributed model of a transmission line. The results of the simulation show the influence of the parameters of the transmission-line enclosure on the impedance curve and resonant frequency of the woofer driver. Among others, this paper is concerned with an active filter design for driving speaker drive units in an appropriate phase relationship in the low frequency region, by means of implementing of DPP drive. A prototype of the flat panel loudspeaker is built according to the described design concept and the results of sound pressure level measurement are presents. The design result from work performed for DSLab and is subject to the referenced patent.
