I have a pair of Servo 15's onroute to me, one from fellow forum user and mate adieacc and the other from Richersounds via ebay Some will be aware that I already have an SVS CS-Ultra so I'm going to be auditioning and pitching them against each other. I will post full test results with subjective and more scientific data such as frequeency plots and max SPL. I will of course be using the Servo's in both single and dual configs. The winner or whatever you want to call it will be kept and the loser sold. Should be interesting!
