In this two-way design, the woofer is a Norwegian Seas custom driver, redesigned by our engineers. Its strong magnetic circuit, specially reinforced with an additional magnet, works with a lightweight aluminum-copper voice coil, which optimizes the mass of the individual components of the vibration system and reduces the impact of the “skin effect” that occurs when current flows through the coil. The result is improved dynamics and better precision in reproducing bass and midbass structure. An aluminum basket with an openwork design also ensures a clean sound. The Diamond Monitor 18 Mk II also features a bass-reflex tunnel with an increased diameter while maintaining similar cabinet tuning. As a result, the lowest frequencies are reproduced with better efficiency, eliminating audible turbulences. Woofer upgrades have also resulted in improved midrange. The use of a 1-inch voice coil guarantees excellent microdynamics in this range. The traditional dust cap was replaced by a phase plug, eliminating resonances associated with the air volume under the dome. The coated lightweight cellulose diaphragm allows for a tonally balanced, warm sound over a wide frequency range. A gentle drop in level at the upper end of the band also allows a smooth transition into the range reproduced by the tweeter. It is a new driver from Danish Scan-Speak with a more powerful neodymium magnet system, reduced voice coil mass, and eliminated ferrofluid. It delivers even better detail and microdynamics at the highest frequencies, with greater efficiency and control. Also new is the dual resonance chamber design, which further reduces the primary resonance of the tweeter. An additional advantage of this speaker is reduced nonlinear distortion. The whole complements an advanced crossover, constructed using only linear components such as air coils and polypropylene capacitors, which improves sound clarity.
