Event Electronics 20/20BAS - Studio Monitor two-way front ported speaker
First released in 1995, the original 20/20 nearfield studio monitor was universally acclaimed and launched the Event brand worldwide. Using manufacturing processes and materials unheard of at the time, the 20/20 combined a magnetically shielded 25mm natural silk dome with an 8" mineral-impregnated polypropylene cone. A laminated and internally dampened MDF cabinet with a front-mounted large diameter bass port assisted in providing the 20/20's impressive low end response.
