M28LA passive modular line array source features 2-way passive (bi-amp) design equipped with 2×8 inch
LF speaker in a port assisted horn loaded configuration allowing for increased sensitivity and SPL.
The multi cell LF horn configuration provides seamless inter-element coupling of the LF driver up to the crossover point. HF section consists of one 1.75 inch annular diaphragm driver coupled to a proprietary wave guide. 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.
M28LA line source element is made of premium grade Baltic birch plywood to provide maximum acoustical and mechanical integrity.
The system is designed to provide the specified performance in a group of minimum 4 boxes. 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.
M28LA line source element is directly stackable on its dedicated M4.18 suwoofer element.
