This Canadian-based company has been part of the electronics industry for decades dating back to the inception of the MOSFET transistor. Always one to innovate, rather than imitate, Knoll Systems engineers, develops, and manufactures a line of high-performance products so robust that there is almost no application, big or small, that they don't have a well thought out and implemented solution for. Further, their exclusive EcoSystem amplifiers consume less energy, without sacrificing performance, to dramatically reduce the operating costs associated with whole house audio systems and safeguard the environment.
