Dayton Audio SIG270-4 10" Signature Series Woofer 120W Driver 4 Ohm
The Dayton Audio Signature Series was designed to give DIY speaker designers access to the pinnacle of speaker technology at the value expected from Dayton Audio. Featuring an open aluminum cast frame, anodized aluminum cone and a polyimide former, these drivers can provide extended range with incredibly low distortion.
The smooth and extended frequency response of these Dayton Audio speaker drivers ensures that its entire audible spectrum is accurately reproduced, from the lowest bass notes to the highest treble frequencies. This well-balanced frequency response delivers a natural and immersive listening experience, allowing you to hear every detail and nuance in your favorite music or movies.
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.
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.
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.
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.
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.
We stand behind our products and our warranty is a demonstration of our commitment to quality and reliability.
