Meticulous Attention to Detail

The speaker drivers’ design, materials, and meticulous engineering work in harmony to minimize distortion, ensuring that the sound remains clean and clear even at high volumes. By achieving low distortion, these speaker drivers provide an accurate representation of the original audio signal, allowing audiophiles to enjoy a true-to-life listening experience with exceptional clarity and precision. The Signature Series speaker drivers used rigorous Klippel testing throughout the design process, a state-of-the-art analysis method to provide optimal performance, consistency, and reliability by precisely measuring and optimizing the drivers’ magnetic and mechanical properties.

Indexed Cone and Surround Junction

Diffraction caused by the abrupt edge of the surround is minimized by the use of an indexed junction. This design feature helps create a smooth transition between the cone and surround, resulting in improved frequency response while improving the rigidity of the cone further resulting in less cone distortion at high excursion.

Vented Polyimide Former with CCA Voice Coil Wire and Elevated Spider Suspension

The polyimide voice coil formers provide excellent mechanical damping and a smoother frequency response, and the copper-clad aluminum (CCA) wire reduces moving mass further enhancing the overall sound quality and increasing the efficiency of the speaker driver. An elevated spider and vented former increases airflow to the coils to keep the assembly running cool during long periods of use.

Concave Black Anodized Aluminum Cone

The aluminum construction of the cone is lightweight, rigid, and helps reduce distortion, contributing to a more accurate sound reproduction. The anodization process is optimized to contribute to the dampening of the cone and provides high aesthetic value to any speaker design.

Open Aluminum Cast Frame and CNC’d Stainless-Steel Badging

The aluminum cast frame keeps movement isolated to the diaphragm, increasing low frequency performance and providing additional thermal dissipation. Stainless-steel badging completes the sleek aesthetic of the Signature Series drivers providing a timeless visual appeal for every speaker designer.
