EVF Series Mechanical Aspects
The EVF full-range and low-frequency systems may be suspended using the 22 threaded rigging points and
supplied EBK-M10-EVI kit of four forged eyebolts (the EVF-1181S and EVF-2151D subwoofers have 28 points).
Clusters can be made using the eyebolt kits but are mechanically simplified by a carefully worked out series of
optional rigging kits, which connect to the rigging points.

Enclosures are available in three degrees of weather resistance:
• EVCoat™ for interior use
• EVCoat™ for interior use
• PI for indirect weather exposure, such as under a roof overhang (EVCoat™ plus stainless-steel
hydrophobic grille and the CDG dual-gland-nut input-panel cover)
• FG for direct exposure (PI grille and input-panel cover plus fiberglass finish)
• External fasteners on all systems are stainless steel
