The D.A.S. HQ-218 is a high-performance externally
powered bass-reflex subwoofer system for use in active
installed systems where bass reinforcement is required.
The HQ-218 system is intended as a flyable point source
system where very high sound pressure levels are in
order, such as indoor or outdoor sport venues, stadiums,
arenas, etc. It can be flown in the same array in
conjunction with other units as the HQ-112.43, HQ-
112.64 and HQ-112.95.
The system comprises one frequency section that is
easily accessed through NL-4 connectors or covered
barrier strip terminals.
The HQ-218 houses two D.A.S. 18LXN, 18” cone
transducer configured as a direct radiators. This long
excursion driver featuresa 4" edgewound coil, massive
magnetstructure and carefully engineered cooling
scheme, resulting in high power handling and low power
compression.
The enclosure is manufactured from multi layer birch
plywood and it is finished as a standard version (CX)
with black ISO-flex polyurea paint. Totally exposed
systems can be finished in fiber-glass. System IP rating
is IP-54.
The cabinet includes 20 x M10 rigging points that are
