Technics SB-65S (around 1977)
The Technics SB-65S is a compact 1-way bookshelf speaker from around 1977, priced at ¥10,800 per unit. The design is simple. One 20cm double-cone full-range driver (model 20PW49S 162K) handles the entire band, with a small equalizer ball at the center of the sub-cone to smooth the high frequencies. Technics rated it at 92 dB/W/m, which is efficient for a modest full-range design.
The cabinet is bass reflex, with the port on the front just below the driver. The driver is mounted from inside and sits in the upper part of the baffle. The finish is silver metallic, which, along with a slightly different driver name, tells the SB-65S apart from the plain SB-65. The front grille is a see-through type made of acoustically transparent material. The inner walls carry sound-absorbing material, and the rear panel is removable and holds the terminal block.
