X15 HiQ reference stage monitor The X15 HiQ is an active coaxial system designed as a reference stage monitor. The enclosure features a 3" diaphragm compression driver coaxially-loaded by a 15" low frequency transducer in a bass-reex cabinet. The L-Vents laminar vented ports reduce turbulence and port noise at high levels to increase LF efciency.

Mechanical safety Flown congurations The X15 HiQ rigging system complies with 2006/42/EC: Machinery Directive. It has been designed following the guidelines of BGV-C1. 2006/42/EC: Machinery Directive species a safety factor of 4 against the rupture. The own deployments described in this manual achieve a safety factor of 5 or more.
Page 24
Soundvision calculations are based on usual environmental conditions. A higher safety factor is recommended with factors such as extreme high or low temperatures, strong wind, prolonged exposition to salt water, etc. Always consult a rigging specialist to adopt safety practices adapted to such a situation.
