In this expert analytical material, you will find seven subwoofers specially selected by the editors - suitable specifically for music installations. The rating starts with relatively inexpensive devices and ends with genuine High-End.

KEF KC92

KEF KC92 continues the proprietary R Meta series and uses two oppositely directed 9” drivers with diffusers made of aluminum and paper. Each of them is powered by its own 500 W D-class amplifier - as a result, the subwoofer easily develops a sound pressure of 110 dB. The control is “smart” - thanks a Music Integrity Engine phase-frequency correction module on board with five settings - as a result, the 20-kilogram model works from 11 Hz - and literally knocks you out with the resolution and texture of the bass.

Velodyne Vi-Q15

The latest development from Velodyne is the VI-Q subwoofer with an automatic room correction module using a microphone from iOS (or Android) smartphones and a built-in DSP processor. Traditionally for the company, a closed box is used here instead of a ported design - due to which filigree work is achieved even with the smallest bass contrasts. An absolutely new long-stroke driver with a super-powerful basket with double ventilation and a diffuser made of carbon fiber and a 650-watt D-class amplifier with peaks up to 1,200 watts, notes from 23 Hz - everything is good here.
