The M2 speaker terminals are designed to accept bare 

wire. Push down on the top of the terminal to open the 

connection hole, insert the bare wire and release the 

terminal to secure the wire.  

IMPORTANT:

Make sure that the (+) 

and (–) bare wires do not come in contact  

or contact the adjacent terminal. Wires in 

contact with each other can cause a short-

circuit that can damage the power amplifier.

The M2’s (+) speaker terminals are red; the (–) terminals 

are black. Always connect the conductors of the speaker 

wire appropriately to the corresponding negative and 

positive terminals on all speaker and amplifier terminals: 

amplifier “+” to speaker “+”; amplifier “–” to speaker “–”. 

This will ensure all components work together in proper 

polarity (sometimes referred to as “in phase”). Connecting 

the speakers with improper polarity (sometimes referred 

to as “out of phase”) can result in reduced low-frequency 

output, impaired stereo effect. and inferior performance in 

the crossover region.

The M2 connector panel has two sets of push-

terminals. The upper set of terminals is for the high-

frequency transducer and the lower set of terminals 

is for the low-frequency transducer. Connect the 

speaker to the high-frequency and low-frequency 

channels of your power amplifier as shown in the 

example below.

note:

 The M2 is designed so that a positive voltage appearing at both (+) input terminals will cause the low-frequency 

diaphragm to move towards the listener and will cause the high-frequency diaphragm to move away from the listener. 

This is necessary to maintain proper phase between the transducer outputs in the crossover region. 

CAUTION: 

Power off amplifiers 

when making connections. 

Making connections while an 

amplifier is operating can damage 

the speaker system and void the 

warranty. Amplifiers should also 

be powered off before connecting 

or disconnecting any components 

in the signal chain.
