The Markaudio CHR-70 Silver 4" Full Range Aluminium Woofer represents a remarkable achievement in compact driver engineering, delivering detailed, full-range audio from a surprisingly small footprint. This 4-inch aluminium woofer is designed to produce a broad frequency response that makes it ideal for high-fidelity loudspeaker builds, including bookshelf speakers, desktop monitors, and small-scale home theatre systems. Its full-range capability also suits it perfectly for DIY audio projects where space is at a premium but sound quality cannot be compromised.

Technically, the CHR-70 Silver boasts an impedance of 8 ohms and a sensitivity of 85.4 dB (SPL 1m/2.83V), ensuring efficient power handling. The aluminium cone material provides rigidity and low mass, contributing to a resonance frequency of 65.4 Hz and a maximum linear excursion (Xmax) of 4 mm. With a total Q factor (Qts) of 0.55 and a mechanical Q (Qms) of 2.66, this woofer offers controlled, accurate bass response. The 19.81 mm voice coil and equivalent volume (Vas) of 5.097 litres further enhance its performance, while the 50.2 cm² cone area (Sd) ensures ample sound projection. Whether you are building a high-end stereo pair or a compact centre channel, this Markaudio driver delivers exceptional clarity and detail across the frequency spectrum.
