The TK-403 2.2.1 channel audio system provides a high level of clarity, impact and excitement. It is a great choice when you want to immerse listeners in a surround sound experience. Each two-way satellite speaker is bi-amplified (the midrange driver and tweeter are each powered by their own separate amplifier channel), thereby eliminating the need for a distortion-inducing passive crossover. The TK-403 system delivers the performance certainty and consistency of self-enclosed speakers.

The PC board style amplifier is ready to be integrated alongside your electronics package. A supplied wiring harness with slip-on connectors makes assembly easy, foolproof and fast. Don't risk less than ideal sound via a la carte product choice, MISCO has done the work for you by pairing the right amplifier with the right speakers.
