Peerless by Tymphany HDS-P830870 Bass-midwoofer

The Peerless by Tymphany HDS-P830870 Bass-midwoofer is a meticulously engineered 4-inch driver designed to deliver accurate and refined mid-bass reproduction. Its polypropylene cone is formulated to minimise distortion, ensuring that every note is rendered with clarity and precision. This makes it an ideal choice for audiophiles and DIY enthusiasts seeking to build high-fidelity loudspeakers or upgrade existing systems where space is at a premium.

This versatile bass-midwoofer excels in both sealed and ported enclosures, thanks to its carefully balanced total Q factor of 0.6. Whether you are constructing a compact bookshelf speaker, a dedicated centre channel, or a multi-driver array for a home theatre setup, the HDS-P830870 provides the controlled, articulate low-end response required for immersive listening. Its modest 101.6 mm nominal diameter and 55 mm depth allow for integration into slim-profile designs without compromising performance.

Technically, the driver features a 5.3 ohm DC resistance and a sensitivity of 84.7 dB SPL at 1 metre with 2.83 V input. The voice coil inductance is a low 0.198 mH, contributing to extended high-frequency response. With a maximum linear excursion of 7.5 mm, it can handle dynamic peaks with ease. The mechanical and electrical Q factors of 1.92 and 0.871 respectively combine to deliver a well-damped, accurate transient response. The 96 mm cut-out diameter and six mounting holes ensure straightforward installation.

In summary, the HDS-P830870 offers a compelling blend of low distortion, balanced performance, and compact dimensions, making it a superb choice for discerning audio projects.
