Peerless by Tymphany NE85W-04 2-1/2" Full Range Woofer

The Peerless by Tymphany NE85W-04 is a 2-1/2-inch full range woofer that delivers remarkably clear and coherent sound across the frequency spectrum, making it an exceptional choice for compact audio designs. This broadband driver excels in applications where space is at a premium yet performance cannot be compromised, such as in small bookshelf speakers, desktop monitors, or multi-channel surround systems where each channel demands a full-range response from a single driver. Its versatility also suits custom installations and portable audio projects where a balanced, natural sound is desired without the complexity of a multi-driver crossover.

Technically, the NE85W-04 is engineered for precision. With a sensitivity of 85.2 dB SPL at 1m/2.83V and a total Q factor (Qts) of 0.68, it offers a well-damped response suitable for sealed or small ported enclosures. The 4-ohm impedance (DC resistance 3.7 ohms) and a maximum linear excursion (Xmax) of 4.89 mm allow for respectable output and dynamics given its compact 85 mm nominal diameter. The low voice coil inductance (Le) of 0.071 mH ensures extended high-frequency performance, while the robust mechanical construction, including a 51.3 mm mounting depth and a 58 mm cut-out diameter, facilitates easy integration into tight spaces. This full-range woofer is a superb choice for achieving high-fidelity sound in minimalist designs.
