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.  
HF Section  
RATED POWER (2)  
LF + MF: 400W AES, 1600W peak  
HF: 75W AES, 300W peak  
FR: 400W AES, 1600W peak  
LF + MF: 99dB  
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.  
SENSITIVITY (6)  
HF: 104dB  
FR: 98dB rising to 103dB at HF  
LF + MF: 124dB continuous, 130dB peak  
HF: 123dB continuous, 129dB peak  
FR: 123dB continuous, 129dB peak  
LF + MF: 12 ohms  
HF: 12 ohms
