Power your KEF Ci-Series installation subwoofer, with the dedicated KEF KASA500.

The perfect match for KEF Ci-Series subwoofer

Featuring a highly efficient Class D amplifier, the KASA500 offers powerful and reliable sound to a single or twin passive subwoofers. Packing a chucky 250 watts per channel (at 4 ohms) two subwoofers can be driven to room-filling volumes. Choose to bridge the amplifier and a single subwoofer benefits from a mighty 500 watts supply.

Configures to a wide range of systems
With both line and speaker level inputs, and DSP configurable pass-through with optional high pass filters, the KASA500 is versatile enough to be used in a wide range of systems. Optional rack mount ears are included for professional rack installation.

Fine tune
All the major adjustments are easily accessed at the front of the amp. Adjust the gain, phase and frequency response. At the back of the unit, you can switch between Stereo/Mono mode, 2 channel/Bridge mode, line out EQ/Pass through mode and Manual/Music Sense/12V trigger modes.

Drive your KEF Ci subwoofer to its optimum, with the KEF KASA500 amplifier.
