The THE12 SUB PRO ACTIVE vented with its slim design covers a wide range of applications, specially due to its lateral bass reflex opening, which makes it the ideal choice for a positioning behind the screen. Low-frequency music and bass effects thus are directly bound into the sonic image. Its remakable efficiency of 90 dB and its extended bandwidth down to 25 Hz allow for an enormous bass impact by at the same time low amplifier power. Achievable sound pressure levels of a constant 120 dB let the performance live up with the greatest of ease, leaving any restrictive limitations behind.
