M44A-Active Bi-Amplified Stage Monitor


M44A is a high-performance self-powered, biamplified stage monitor designed for those requiring higher sound pressure level and greater definition, together with the typical punch of 15" loudspeakers, in this case a neodymium coaxial custom unit with built-in 1,5" HF driver. 
Not only does the coaxial design allow for a greater sonic accuracy, but it also makes possible significant space savings on the size of the baffle, for an easier handling also on smaller stages.


• High sound pressure level with maximum definition, absolutely flat frequency and phase responses.

• Low susceptibility to feedback. Excellent intelligibility, no distortion or coloration.

• 129 dB max SPL.

• 2 class AB MosFet power amplifiers deliver a total output power of 
500 W (LF 350 W, HF 150 W).

• 2 indipendent dedicated dynamic processors.

• Active cross-over filter (24 dB/oct Linkwitz-Riley, 1000 Hz).

• Specially designed coaxial unit: 15” neodymium magnet woofer; 
1.5” neodymium compression driver with titanium diaphragm 
and 3” voice coil.

• Strong and sturdy cabinet made from high grade phenyl-glued multiply birch and finished with highly resistant antiscratch polyurethane black paint.

• Low turbulence tuning ports. 

• Ergonomically designed handle, balanced to the box’s centre of gravity, make transport easier.

• Controls and connections are conveniently placed on one side of the cabinet for increased ease of use.



• M44A has been specially designed to provide elevated sound pressure levels without neglecting any detail of the low-pitched range. It is the perfect solution for drummers and bass players, guaranteeing excellent performance even under the most challenging stage conditions.

• The dual angle cabinet’s profile allows for maximum setup flexibility and helps in optimizing listening, from short or long distances.
