Peerless by Tymphany HDS-P830992 4" GFC Cone HDS Woofer

The Peerless by Tymphany HDS-P830992 4-inch GFC Cone HDS Woofer is a precision-engineered bass and mid-bass driver designed to deliver exceptional audio performance in compact loudspeaker systems. This woofer excels in applications where space is at a premium but high-quality sound reproduction is non-negotiable, making it ideal for bookshelf speakers, small subwoofer enclosures, or custom automotive audio builds. Its balanced design ensures accurate reproduction of both low frequencies and midrange details, offering a cohesive listening experience across a wide range of music genres and home theatre content.

Technically, this driver features a robust glass fibre cone membrane that provides excellent stiffness-to-weight ratio, minimising cone breakup and ensuring clean, controlled sound. With a linear excursion (Xmax) of 7.5mm, it achieves low-distortion output even at higher volumes, while the sensitivity of 85.5dB SPL (1m/2.83V) ensures efficient power handling. The total Q (Qts) of 0.66, combined with a mechanical Q (Qms) of 2.17 and an electromagnetic Q (Qes) of 0.94, indicates a well-damped driver suitable for sealed or ported enclosures. The 4-inch nominal diameter (101.6mm) and 63.4mm mounting depth allow for versatile integration, while the 5.2-ohm DC resistance (Re) and low voice coil inductance (Le) of 0.23mH contribute to stable impedance and extended frequency response. Whether for upgrading existing designs or building new projects, this woofer delivers reliable, high-fidelity bass and midrange performance.
