Adamson S-Serie S7


The S7 is a 2-way, full range line array cabinet containing 2x ND7-LM16 Kevlar Neodymium drivers (2x 16 Ω) and an NH3-8 1.4” exit compression driver (8 Ω). The critically optimized sound chamber produces a slightly curved wavefront with a nominal dispersion pattern of 100° x 12.5° (H x V). The chamber’s efficiency allows for increased vertical dispersion without sacrificing high frequency presence in the far field. Patented Controlled Summation Technology further eliminates low-mid lobing normally associated with 2-way line source systems.
The cabinet construction uses marine grade birch plywood as well as aircraft grade steel and aluminum, and is equipped with two Speakon™ NL4 connectors. The SlideLock rigging system ensures easy yet secure setup and teardown.
The S7 is suited to a wide variety of applications. Its full range capability (80 Hz) at reasonable levels qualifies for applications where sub is not required. Increased vertical coverage (12.5°) enables the S7 to cover theaters and small arenas with reasonable speaker quantity. Other target applications include dance clubs, corporate events and contemporary churches.
