The M26LA passive modular line array source features 2-way passive (bi-amp) design equipped with 2×6.5 inch LF speaker with 2.5 inch voice coil  mounted in a port assisted configuration allowing for increased sensitivity at the low end.

HF section consists of one 1.75 inch voice coil annular diaphragm driver with 1 inch exit, coupled to a proprietary high frequency wave guide and horn assembly that provides seamless inter-element coupling.

The box configuration generates a symmetrical 90 degree horizontal coverage with no apparent lobes in its entire frequency range.

Each of the system elements can be curved up to 16 degrees without breaking the inter-element acoustic coupling.


M26LA line source element is made of premium grade Baltic birch plywood to provide maximum acoustical and mechanical integrity.

Each element has a nominal 16 ohm impedance and the system is driven by a dedicated amplifier and DSP units as a fully integrated system which provides clean undistorted power with a significant headroom and excellent system protection.
