The high-performance O 900 studio subwoofer is the ideal complement for the O 500 C studio monitor. Precise bass reproduction is achieved down to 17 Hz (- 1.5 dB). The 120 liter cabinet gives a high maximum sound pressure output with a flat frequency response. This is due to the ingenious enclosure design, as well as the use of uncompromisingly constructed drivers.
The O 900 can use the analog subwoofer output of the O 500 C and an external amplifier
(KPA 2220 recommended).
