GETTING STARTED: The M-20 is unique in that it combines a dedicated control amplifier with a separate loudspeaker cabinet, using controlled impedance cables that actually form part of the crossover network.
Portions of the M-20’s crossover circuitry are located in both the amplifier and speaker enclosures, and the cable supplied is an important part of this electrical network. This allows the speaker cable to function as a neutral and transparent component in the system. Replacing or extending the supplied cable with any other type will have a varying and unpredictable impact on the sound.
The M-20 controls are designed for utility and repeatability under varying conditions and make only subtle impact on the basic character and accuracy of the speaker. We encourage you to experiment with fine tuning the system to your particular requirements.
BOUNDARY CONTROL: Reflective boundaries, such as floors, walls, even table tops, reinforce a speaker’s low frequency output. Conversely, placing speakers out into a room decreases bass response. The greatest low frequency output is with the BOUNDARY control in the “0” position, which assumes no significant boundary reinforcement is present.
