Klein + Hummel O 900 Studio-Subwoofer

The O 900 studio subwoofer system can be used with a stereo or 5.1 surround monitoring system and - depending on the chosen configuration - will require some or all of the components shown below:

• O 900 - Studio Subwoofer
• PRO A 2000 - Stereo Power Amplifier
• PRO C 28 - Digital FIR Controller
• PRO M 68 - Bass Manager
• O 300D / O 400 / O 500C - Active Studio Monitors

• High performance studio subwoofer with 2 extra long excursion 12“ woofers
• Extremely low frequency reproduction down to 17 Hz (-1.5 dB)
• Very articulate and accurate bass with excellent impulse response
• Maximum sound pressure with remarkably low distortion
• An excellent low frequency complement to studio monitors O 300 D, O 400 and O 500 C
• Magnetically shielded
• Operation through „sub“ output of digital monitor O 500 C or digital controller Pro C 28 applying FIR-filter technology
  

• Pressure diecast aluminum basket with maximum air flow
• Rear vented voice coil design contributes to the production of very high sound pressure levels with minimal power compression
• Extremely long driver excursion of +/- 50mm yields exceptionally low distortion
• Patented polimeric impregnated Nomex® Kevlar® composite-cone produces a high degree of self damping and lowest distortion at very high excursion
• A demodulation ring reduces distortion and increases heat dissipation
  

• Rigid enclosure design avoids resonance and yields accurate detailed bass, linear bass response, independent of volume and higher sound pressure levels
• Large bass reflex ports eliminate unwanted air noise
• Enclosure design can accomodate optional stacking of the O 500 C studio monitor
