The W8LMI is a compact line array enclosure designed to bring line
array performance to small and medium scale applications in the fixed
installation market. It features the same acoustic components and
construction as the touring W8LM as well as a custom-designed
integral flying system tailored to the needs of a fixed installation
environment, such as theatres and indoor venues. The flying hardware
is rated at 7:1 for 12 cabinets and is compatible with the W8LM flying
frame and lifting bar.
Following the constant directivity horn design philosophy of the W8L
and the W8LC, the W8LMI is a three-way system that combines line
array principles with innovative horn loading techniques to produce a
next generation, small line array with maximum dynamic impact.
