Due to Martin Audio’s policy of continuing improvement, we reserve the

The W8LMDI is a mini, very wide-dispersion vertically arrayable
enclosure. It can be used individually and in small quantities for short
to medium throw applications (up to 30 metres) as well as a downfill
element for W8LMI systems.
Constant directivity horns are used for high and mid frequencies,
ensuring consistent on and off axis performance. The high frequency
horn generates the correct Wavefront curvature to provide optimum
inter-cabinet summation and to seamlessly integrate with W8LMI
arrays. Our revolutionary HiBlade™ device, patent pending, projects
the ultra-high frequencies right out to the extremes of the 120°
horizontal dispersion pattern. Conventional constant directivity horns
are unable to match this performance without making significant
compromises to other aspects of the design.
