Both inside and outside have been brushed up! A theater speaker system that represents Altec as the “Voice of the Theater.” This time it will be a late model of the Manta Ray horn. The driver uses 291-16K, and the mid-high range that shakes the air, and the light low frequency that jumps forward using the 515E are sounds unique to the A5. The exterior is beautifully finished with exterior repairs. (Satoshi Yonejima)

The price has been reduced. 2022/8/6 selling price 498,000 yen Maintained! It is a stereo amplifier of PASS that represents modern American sound, and boasts a straight, dynamic, and surprisingly instantaneous drive power. The sound image is also thick and drives a large JBL speaker. The texture of the mid-high range is high and the vocals are expressed smoothly. There is a small scratch on the heatsink (Yosuke Kojima)
