Fully maintained! Early type all-alnico! JBL5234 channel divider included! The low frequencies like the noise of the earth pumped out from the double woofer, the mids that fly like a shower, and the high-pitched highs are just a few words of masterpiece. The exhilarating sound combined with the awakening blue baffle is a sense of fulfillment and overwhelming presence that cannot be obtained with other models. The appearance is also neatly finished by maintenance. * Since it is designed with a multi-amplifier system, two power amplifiers are required. The edge is a chamois edge (Murakoshi Yoichi)
