Maintained! The strength of the extrusion of the entire range and the clear sound are truly sounds unique to the heyday of JBL. The mid-high range with a unique sense of spaciousness and strong linearity makes hard bop and trumpet sounds pleasant. The sense of volume in the mid to low range is also attractive not found in modern speakers. The exterior has been beautifully finished due to maintenance (Mizusaki Ryo)

Fully overhauled on 2023/12/13! A JBL professional series speaker that combines the mid-high range of a biladial horn, which is characterized by wide directional characteristics, and a 38cm woofer with excellent low frequency reproduction. It is possible to combine high range stretchability while maintaining 2-way mid-range energy in response to professional field requests.

Fully maintained! 2-way floor speaker with a double woofer and 1 horn. With the benefit of the 2234H woofer, which has a fast response and is highly efficient, I have the impression that it is very easy to sound even though it is a double woofer. Coupled with the excellent penetration of the biladial horn, it develops a very energetic sound stage. The good positioning unique to 2WAY is also a good impression. It has a beautiful finish due to exterior maintenance (Oikawa Tetsuji)
