ESCRIPTIONS

The M82i is a unique near-field speaker combining hi-fi properties with

high SPL's in a very compact design.  

M82i is a 2-way speaker designed as a dedicated top-box and should be

supported by the M151i subwoofer below 100 Hz. It houses two 8" mid-

woofers with very extended frequency response and two 1" soft dome

horn tweeters cooled by magnetic oil. It has a highly controlled dispersion

pattern of 60x60 degrees. The M82i has been designed specifically for

applications in which clarity and speech intelligibility is needed, but is also

ideal for smaller clubs and as fill in near-field applications. 

The pressure camber cabinet is designed around an extruded 2mm alumi-

nium profile. The M82i offers four built-in flying points for easy horizontal or

vertical fixing. A customised multi bracket is available as well. The trapezo-

idal cabinet shape allows flexible and discrete fixing in low ceiling applicati-

ons. The M82i can be fittet with an external top-hat adapter.

This model is also available in white.
