E12
The Adamson E12 is a 3 way, true line source enclosure, incorporat-
ing proprietary transducer and waveguide technology which reduc-
es weight and minimizes its footprint. The heart of the E12 is the
E-Capsule, which is precisely engineered and constructed of lightweight
aluminum. The patent pending skeletal structure provides an accurate
and rigid frame for mounting the modular aircraft grade steel Autolock™
rigging system, while simultaneously housing ultra-efficient mid-high
components coaxially mounted on Adamson’s newly modified E12
Co-Linear Drive Module.
A vector corrected low-excursion 7” Kevlar Neodymium midrange
transducer paired with a next generation 4” HF compression driver
energize the drive module and provide seamless mid-high energy with
no audible distortion at very high SPL levels. The critically optimized
waveguide, based on a prolate-spheroidal geometry ensure precise
pattern control and minimum THD, producing a dispersion pattern of
110° x 8° (H x V). The E-Capsule is flanked with two separate birch ply
enclosures, each containing Adamson’s proprietary Kevlar Neodymium
12” woofer, capitalizing on the advantages of Adamson’s Advanced
Cone Architecture and optimized heat dissipation management of the
4” voice coil.
