Peerless by Tymphany SDS-P830657 6-1/2" Paper Cone SDS Woofer

The Peerless by Tymphany SDS-P830657 is a 6-1/2-inch woofer engineered to deliver articulate, controlled bass and mid-bass performance. Its treated paper cone combines lightweight responsiveness with natural damping, ensuring clean transients and minimal coloration across the frequency range. This driver is an excellent choice for high-fidelity loudspeaker designs, automotive audio upgrades, and custom subwoofer systems where accurate low-frequency reproduction is paramount.

With a total Q factor (Qts) of 0.47, this woofer is equally suited to sealed or ported enclosures, offering flexibility for both compact and extended bass designs. The 5.46 mm of linear excursion (Xmax) supports dynamic output without distortion, while a sensitivity of 89 dB (SPL 1m/2.83V) ensures efficient power handling. The 5.9-ohm DC resistance and 0.591 mH voice coil inductance contribute to stable impedance and controlled motor behaviour. Mechanical (Qms 2.67) and electromagnetic (Qes 0.565) damping are well balanced, promoting tight, musical bass.

The 165.1 mm nominal diameter fits a 144 mm cut-out, with six mounting holes on a 170.7 mm bolt circle for secure installation. A mounting depth of just 77.4 mm allows integration into shallow enclosures. The treated paper cone retains the classic warmth and detail that discerning listeners value, making this woofer a reliable foundation for your next audio project.
