IS7c Ultra Compact Point Source

• The IS7c is an ultra-compact, lightweight, point source enclosure with a 90° conical dispersion pattern. Within the enclosure is a passive crossover and Adamson’s ND7-C, a coaxial transducer that 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 that 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 sacrificing low resonance to the 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 fill 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 amplifiers. The nominal impedance of the IS7c is 16 Ω, maximizing amplifier efficiency.

Wiring

• The IS7c (96X-000X, 96X-500X) comes with 2x Neutrik Speakon™ NL4 connections, wired in parallel, as well as an external barrier strip.
• Pins 1+/- are connected to the internal crossover.
• Pins 2+/- are not connected.

Amplification

• The IS7c is paired with Lab Gruppen D-Series amplifiers.
• Maximum quantities of the IS7c per amplifier model are shown below.

For a master list, please refer to the Adamson Amplification Chart, found here, on the Adamson website.

Presets

• The Adamson Load Library contains presets designed for the deployment of the IS7c.
• There are presets designed to pair with either Adamson subs or Adamson Line Arrays.
• For a master list, please refer to the Adamson PLM & Lake Handbook, found here, on our website.

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 distinctively smooth finish that allows for easy cleaning and removal of contaminants like dirt, grime, salt water or sand.
• To protect against dust and other particles, a fine 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 jack plate, with gland nuts in place to seal the connection points.
