Markaudio Alpair-5 Grey Full-range Woofer

The Markaudio Alpair-5 Grey 3" Full Range Aluminium Woofer is a remarkably compact driver that delivers a surprisingly open and natural sound, making it an excellent choice for high-fidelity audio projects where space is at a premium. Despite its small footprint, this broadband subwoofer is engineered to produce clear, articulate midrange and impressive bass extension, challenging expectations for a driver of its size.

Ideal for use in desktop speakers, small bookshelf designs, or multi-channel home theatre systems, the Alpair-5 Grey excels in applications where a single driver can cover the critical frequency range without the need for a separate tweeter. Its full-range capability makes it particularly suited for near-field listening, DIY audio builds, or upgrading existing compact enclosures where sonic clarity and coherence are paramount.

Technically, the driver features a paper cone membrane mounted on a rigid aluminium chassis, which together minimise unwanted resonances and distortion. With a total Q factor (Qts) of 0.4986 and a mechanical Q (Qms) of 2.301, it offers well-damped, controlled bass response. The 3.4 ohm DC resistance and 85.45 dB sensitivity ensure efficient power handling, while a maximum linear excursion (Xmax) of 3 mm allows for surprising low-end output. The 76.2 mm nominal diameter and 39 mm depth fit neatly into compact enclosures, with a 79 mm cut-out diameter and four mounting holes on a 90.5 mm bolt circle for straightforward installation.

In summary, the Markaudio Alpair-5 Grey is a versatile, high-performance full-range driver that brings natural midrange and extended bass to compact audio systems, all while maintaining low distortion and easy integration.
