Because MK Sound alone dictates the specifications for our drive units down to the very last detail, based on extensive original experimentation and research, our loudspeakers are not subject to the changing whims and fads of standard off-the-shelf drive units.
MK Sound proudly works to a higher, stricter standard, implementing meaningful changes as technology advances.
The dual 5.25” 150 woofer configuration employs a pin-cushion basket design with narrow basket flange to permit close placement of two woofers on a compact baffle. Modest baffle dimensions ensure structural integrity, while eliminating destructive diffraction phenomena.
A completely open cast aluminum basket structure with four solid pillars allows unimpeded airflow on both sides of the cone and around all moving parts for immediate heat dissipation. Unlike conventional baskets designed with a plateau for spider mounting, the MK design team opted for a cup spider design, ensuring absolutely free airflow.
The development of cone and surround, crucial components with major impact on ultimate sound quality, was a collaborative effort with Peerless, leading Danish transducer specialists intimately familiar with MK Sound’s design objectives after decades as supplier and partner.
Working closely, MK Sound and the Peerless transducer team (Among the world’s foremost transducer designers, Peerless was founded in Denmark in 1926.) developed a breakthrough cone geometry, optimized to work in combination with a unique polypropylene based diaphragm material. The Polypropylene base, infused with 20% carefully selected minerals, provides a perfect balance between cone stiffness and internal damping.
The woofer’s low reflectivity cone is the result of a carefully calibrated combination of materials and geometry with a low-loss SBR rubber surround and edge resonance stabilizer.
