The BM1651 Bass-midwoofer from Volt Loudspeakers represents a meticulously engineered driver for discerning audio enthusiasts who demand precision and control in their loudspeaker designs. This dedicated bass-midwoofer is ideally suited for use in high-fidelity two-way or multi-way systems, where it excels at delivering articulate, well-defined low frequencies and a seamless transition to the midrange. Whether you are constructing a pair of standmount monitors or a floor-standing loudspeaker, this driver provides the foundation for a truly immersive listening experience.

Technically, the BM1651 is defined by its low total Q factor of 0.24, which ensures tight, accurate bass response with minimal overhang, making it particularly well-suited for sealed or vented enclosures. The driver features a 165.1 mm nominal diameter with a maximum linear excursion of 6.3 mm, allowing it to move significant air volume (Vd of 96.98) while maintaining low distortion. Its sensitivity is rated at 88 dB SPL at 1 metre with 2.83 V, and the 5.5 ohm DC resistance ensures compatibility with a wide range of amplifiers. The electromagnetic Q (Qes) of 0.26 and mechanical Q (Qms) of 4.12 contribute to its excellent transient response. With a mounting cut-out diameter of 16 mm and a depth of 90 mm, this driver is designed for straightforward integration into your project, delivering the controlled, authoritative bass that defines Volt Loudspeakers’ engineering excellence.
