IS7c
• The IS7c is an ultra-compact, light-weight, point source enclosure with a 90° conical dispersion pattern. Within
the enclosure is a passive crossover and Adamson’s ND7-C, a coaxial transducer which contains both a 7” low
frequency section and a dome compression driver..
• The operational frequency range of the IS7c is 80Hz to 20kHz. A high maximum SPL of 130 dB.
• The enclosure has an unobtrusive visual design which blends seamlessly into the surrounding space, is made
of marine grade birch plywood, and has steel rigging discs on the top and bottom, to be used with rigging
accessories. Without sacricing low resonance to composite material, the IS5c weighs only 5.44 kg / 12 lbs.
• The IS7c is intended to be used as either a standalone system, or a ll enclosure in tandem with other IS-Series
products. The IS7c is designed to pair easily and coherently with all IS-Series subwoofers.
• The IS7c is designed for use with Lab.gruppen’s D-Series line of installation ampliers. The nominal impedance of
the IS7c is 16 Ω, maximizing amplier efciency.

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 are rated IP55 and 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 fi 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 fi 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.
