The construction features a large, custom-designed 15-inch woofer with a classic paper cone and a powerful magnetic system, ensuring sound with tremendous scale and dynamics, reaching the lowest registers unattainable by smaller designs. The proprietary midrange driver, like the woofer, utilizes a paper cone and is equipped with a precisely designed phase corrector in the form of an aluminum cylinder with specific geometry. The absence of a dust cap in this driver results in a clean midrange, free from coloration and resonances. A BMS compression tweeter driver, working in a custom-designed short horn with a Tractrix profile, allows for precise and detailed high frequencies without the harshness commonly associated with horn-loaded speakers. Thanks to the careful selection of drivers and their parameters, we achieved relatively high efficiency with an easy 8-ohm impedance. The uncompromising crossover, made from linear components and foil capacitors, enables maximum fidelity and naturalness of sound reproduction.
