Zusammenfassung:	PURPOSE:To expand the reproducing band area of a system stereophonic device by using the same speaker unit in right and left speaker systems, and loading them on cabinets having different bass-reflex ports, respectively. CONSTITUTION:The stereoscope device is comprised of the speaker system with bass-reflex resonance frequency consisting of speaker units 12, 13 and the bass-reflex ports 14a, 14b, and the speaker system with the bass-reflex resonance frequency different from that of the above speaker system. Namely, the bass-reflex resonance frequencies of the speaker system 11 of two right and left channels are set differently, and one of them is set as the same resonance frequency as a conventional one, and the other as the resonance frequency lower than the conventional one compared with the conventional same bass- reflex resonance frequency. In such a way, it is possible to expand a low-pass reproducing band area.
