In this three-way design, two woofers from the Prestige series by Norwegian Seas guarantee depth, speed, and dynamics in the lowest frequencies. It is all possible thanks to their massive magnetic circuits, significantly larger than their predecessor, enlarged 1.5-inch diameter aluminum-copper voice coils, and a design that ensures a more piston-like operation. The midrange driver is also Seas’s design, modified by our engineers. Especially for the Diamond 30 Mk II, the phase plug replaced the popular dust cap in the center of the diaphragm. The space under the protective disc, and thus its resonances, was eliminated, reducing upper midrange coloration. In addition to high dynamics, the drivers provide excellent detail transmission and faithful vocal reproduction. All three speakers are made using Spider Ring technology, designed to enhance control over the manufacturing process of high-end products. The tweeter from Danish Scan-Speak has also been updated 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.
