IS118
• 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 sacricing 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 ampliers. The nominal impedance of
the IS118 is 8 Ω.

The IS118 (992-0010, 992-5010) comes with 4x Neutrik Speakon™ NL4 connections, wired in parallel. The 2 rear
connections pass pin 1 +/- to the driver and the 2 front connections pass pin 2 +/- to the driver.
The IS118b (992-0011, 992-5011) comes with an external barrier strip mounted to the rear grill. Terminals 1, +/- are
passed to the driver, terminal 2, +/- are not connected.
To operate the IS118b in FB or FBF cardioid mode, swap the front and rear grills by:
1. Removing the six screws holding each grill to the side rigging pieces
2. Unclipping the grill with the barrier strip from the rear PCB, and swapping the grills
3. Re-clipping the grill with the barrier strip to the front PCB and afx with the same screws

When flown in the same array as an IS7, all IS118 presets contain the inherent delay needed to be properly phase-
aligned.
When flown or ground stacked separately, IS118 subs should be phase-aligned using measurement software.

Weatherized
IS-Series weatherized models add an additional layer of environmental and corrosion protection to Adamson’s
already durable cabinet design. Weatherized enclosures are ideal for marine and coastal venues, outdoor stadiums,
open-air performance spaces, and other permanent outdoor installations.
IS-Series weatherized cabinets feature the following additional protective features.
Corrosion resistance
Corrosion resistance extends the lifetime performance of your system in outdoor venues where water, salt and
acidity can impact durability and function.
All structural steel elements of Adamson weatherized cabinets – including rigging and rigging links – are made of
a high yield strength stainless steel alloy that offers 100% corrosion resistance.
Cabinet hardware is made of non-plated stainless steel, designed to provide exceptional rust and corrosion
resistance, particularly in high-saline environments.
Environmental sealing
Additional protection of the cabinet helps ensure that loudspeaker performance isn’t impeded by the harsh
environments in which your system is deployed.
To guard against water and particle intrusion, the same two-part polyurea coating that gives Adamson cabinets
their life-extending exterior protection is applied to the interior of the enclosure, creating a complete seal.
Weatherized models feature an exterior coating with a distinctive smooth nish that allows for easy cleaning and
removal of contaminants like dirt, grime, salt water or sand.
To protect against dust and other particles, a ne stainless steel mesh has been added to all points of entry
including behind the front grille screens.
Cabling for the IS-Series weatherized cabinets is pre-wired and protected inside a gasket-sealed jackplate, with
gland nuts in place to seal the connection points.
