The CHR-70 Black 4" Full Range Aluminium Woofer from Markaudio represents a refined approach to compact audio reproduction, delivering exceptional clarity and balance in a small footprint. This broadband driver is engineered to produce a cohesive, full-range sound without the need for a separate tweeter, making it an ideal choice for discerning audiophiles and DIY enthusiasts alike.

Perfectly suited for use in small to medium-sized enclosures, this woofer excels in bookshelf speakers, desktop monitors, and high-fidelity multimedia systems. Its full-range capability also makes it a popular selection for custom installations where space is at a premium but sound quality cannot be compromised. Whether you are building a dedicated stereo pair or upgrading an existing design, the CHR-70 Black offers versatile performance across a wide variety of applications.

Technically, this driver features a 4-inch aluminium cone membrane, which provides a stiff yet lightweight diaphragm for accurate transient response and low distortion. With an impedance of 8 ohms and a sensitivity of 85.4 dB (SPL 1m/2.83V), it pairs well with modest amplification. The total Q factor (Qts) of 0.55 and a resonance frequency (Fs) of 65.4 Hz allow for flexible enclosure tuning, while the 4.3 mm linear excursion (Xmax) ensures controlled bass output. Additional specifications include a DC resistance of 7.2 ohms, a voice coil diameter of 19.81 mm, and an equivalent volume (Vas) of 5.097 litres, all contributing to its refined acoustic behaviour.

In summary, the CHR-70 Black is a meticulously engineered full-range driver that combines technical precision with practical versatility, offering a premium solution for compact audio projects.
