Unfortunately we cannot recommend any specific brand of amplifier to use with our Professional products as a matter of company policy. We recommend that you check the specifications of both the amplifier and loudspeaker to ensure they are compatible paying close attention to power rating and impedance values. We also recommend that you consult your local hi-fi dealer who should be able to offer further advice.  For our professional install range, we would absolutely recommend using Lab Gruppen amplifiers. Lab Gruppen are part of TC Group of companies alongside Tannoy, TC Electronic, Blue Microphones and Lake Processing.
