- The Eklipsa array is available in both a 12-inch bi-amped version and a 15-inch bi-amped version. Both of these arrays boast Adamson’s Advanced Cone Architecture together with Adamson’s high frequency wave shaping technology. Both of Adamson’s proprietary, ND12, 12-inch neodymium low-mid transducer and ND15, 15-inch neodymium low-mid transducer, feature a progressive Kevlar cone geometry that reduces modal behavior, providing an improved and linearized pass-band throughout the vocal range. The high frequency wave shaping sound chambers insure a uniform wave front that does not interfere with the adjacent enclosures in the array.
