Our Take On The KEF KASA500
To power your KEF Ci Sub, such as the Ci3160RLb-THX In-Wall Subwoofer, you are going to need a KASA500 DSP Controlled Subwoofer Amplifier. These products are designed to be used together and the subwoofer cannot be used with any other amplifier. The KASA500, however, can be used with other KEF Ci Subwoofers such as the Ci200QSb-THX, Ci200TRb, Ci4100QLb and Ci250RRb.
Set up correctly with a single Ci3160RLb-THX will result in spectacular low end energy and drive and for even more impact and control two Ci3160RLb-THX In-Wall Subwoofers can be used with one KASA500 Amplifier for maximum low end grunt.
KEF's installed subwoofers offer incredible sonic performance whilst remaining visually discreet, and they are all engineered to partner any of KEF's architectural speaker ranges. Plus, when powered by KEF's DSP-driven KASA500 install audio system amplifier, the Ci3160RLb-THX, Ci250RRb-THX and Ci200QSb-THX subwoofers achieve the intense bass performance levels required for THX Certified Select and THX Certified Ultra.
