6-1/2" Poly Cone Midbass Woofer 4 Ohm

This polypropylene-cone bass-midwoofer is engineered to deliver clean, controlled bass response for discerning audio enthusiasts. Its robust construction makes it an ideal choice for custom speaker builds, replacement drivers in existing cabinets, or as a dedicated mid-bass unit in multi-way systems. Whether you are designing a compact bookshelf speaker or a more ambitious floor-standing design, this driver offers the versatility to perform with authority.

At the heart of this driver lies a polypropylene cone membrane, chosen for its excellent damping properties and consistent performance across the frequency range. With a nominal diameter of 165.1 mm and a mounting cut-out of 142.9 mm, it fits standard 6.5-inch baffle openings. The copper voice coil wire ensures efficient power handling, while the 3.5 mm maximum linear excursion (Xmax) allows for articulate, distortion-free bass reproduction. An 88.3 dB SPL sensitivity at 2.83V ensures ample output even with moderate amplifier power. The total Q factor (Qts) of 0.95, combined with a mechanical Q (Qms) of 2.99 and an electromagnetic Q (Qes) of 1.4, indicates a well-damped driver suited for sealed or ported enclosures. The DC resistance (Re) of 3.37 ohms and voice coil inductance (Le) of 0.48 mH further contribute to predictable, linear performance.

This bass-midwoofer is a reliable foundation for any project demanding precise, punchy low-end reproduction. Its thoughtful engineering and quality materials ensure lasting performance and sonic satisfaction.
