IS118
IS118 Ultra Compact Subwoofer
•
The IS118 is an ultra-compact subwoofer enclosure designed for extended LF capabilities. It contains one ND18-S
18" LF driver.
•
The operational frequency range of the IS118 is 35 Hz to 100 Hz. The use of proprietary techologies such as
Advanced Cone Architecture give the IS118 an extremely high maximum SPL level.
•
The enclosure has an unobtrusive visual design which blends seamlessly into the surrounding space, including
identical grills at the front and back so cardioiod deployments appear identical to non-cardioid. It is made of marine
grade birch plywood, and has an aluminum rigging system mounted on each corner. Without sacrificing lowered
resonance to composite material, the IS118 is able to maintain a low weight of 39 kg / 85 lbs.
•
Up to sixteen IS118 can be flown when using the IS7 & IS118 Support Frame and can also be flown in the same
array as the IS7 when using an additional IS7 & IS118 Support Frame. Always consult Blueprint AV™ and the IS-
Series Line Array Rigging Manual for correct rigging positions (including ground stacking options) and installation
procedures.
•
The IS118 is intended to be paired with the IS7 Ultra Compact Line Array with a crossover frequency of 80 or 100
Hz, depending on the preset used.
•
The IS118 is designed for use with Lab.gruppen's D-Series line of installation amplifiers. The nominal impedance of
the IS118 is 8 Ω.
