The M4 employs multiple bracing positioned at critical resonance nodes. The two 6.5-inch MMP®II drivers have been designed specifically for the M4. The lower unit handles bass only, the other provides punchy upper bass and a clear, natural mid-band right up to the crossover point with the tweeter at 2.6 KHz. Unlike the M2, Monitor M4 has a reflex port at the rear as well as the front. This is to provide maximum airflow at low frequencies and reduces air pressure that can lead to bass compression effects.
For medium to large rooms or systems dedicated to home cinema, the rear port can be blocked with a foam bung to tailor the bass response. This allows greater placement flexibility in smaller rooms. The effects are lower bass extension at the expense of bass impact.

Nothing has been carried over, nothing modified or tweaked. The Monitor series bass-mid drive unit, with its professional-grade 8-point cap-head bolt fixings, is new from front to back. MMP®II is an advance in driver technology developed from Monitor Audios original MMP® (Metal Matrix Polymer) cone material and uses a high-pressure injection moulding process to achieve different thickness at critical points of the cone geometry. MMP®II provides better stiffness and consistency and tighter production tolerances resulting in superior sonic performance.

The new bass-mid chassis design has a vented rear section that reduces thermal power compression to deliver increased dynamic range and higher sound pressure levels. This venting also lowers distortion by balancing the pressure within the motor system. It means clean, crisp bass and an even clearer midrange.

High frequency performance has been improved in line. The original Bronze series was praised for the clarity, extension and smoothness of its Gold Dome C-CAM® tweeter. But the new Monitor series sets even higher standards. Further development of the C-CAM® tweeter - in particular the profiling of its surround and a new front plate design - has resulted in a still smoother response and better dispersion.

The emphasis on sound quality and engineering follows through to the crossover which uses high grade polypropylene film capacitors, a low distortionlaminated core and air core inductors. And to the new reflex port design. The inside of the tube has a smooth, soft rubberised coating which greatly reduces air turbulence and unwanted noise. Faster transfer of air results in tighter, more precise bass performance.
