Markaudio Alpair-5 Gold Full-range Woofer

The Markaudio Alpair-5 Gold 3" Full Range Aluminium Woofer represents a remarkable achievement in compact driver engineering, delivering natural, full-range sound from an exceptionally small footprint. This 3-inch aluminium cone driver is designed to bring high-fidelity audio to spaces where conventional speakers simply cannot fit.

Ideal for DIY audio enthusiasts and custom speaker builders, this broadband subwoofer excels in compact speaker designs, desktop monitors, and high-fidelity multi-way systems. Its versatile performance makes it equally suitable for both standalone full-range applications and as part of a more complex crossover-based setup, offering remarkable clarity and detail across the frequency spectrum.
