Two vector corrected low-excursion 7” Neodymium midrange transducers paired with two next generation 4” HF compression drivers energize the drive modules and provide seamless mid-high energy with minimized distortion at very high SPL levels. Critically optimized waveguides based on a prolate-spheroidal geometry ensure precise pattern control and minimum THD, producing a nominal (-6 dB) dispersion pattern of 90° x 6° (H x V). The E-Capsule is flanked with two separate, vented birch ply enclosures, each containing Adamson’s proprietary Neodymium 15” woofer, capitalizing on the advantages of Adamson’s Advanced Cone Architecture and optimized heat dissipation management of the 4” voice coil.
