Dayton Audio HARB252-8 1" x 5" Dual Motor High Aspect Ratio BMT Speaker Driver 8 Ohm

The Dayton Audio HARB252-8 is a meticulously engineered 1" x 5" dual motor high aspect ratio BMT speaker driver, designed to deliver deep, controlled bass from remarkably compact enclosures. As a full-range driver, it excels in applications where space is at a premium yet uncompromising low-frequency performance is demanded. This driver is ideally suited for use in slimline subwoofer systems, under-seat automotive installations, or as part of a high-fidelity home theatre setup where discreet integration is key. Its unique form factor allows for creative enclosure designs that traditional round drivers cannot accommodate.

Technically, the HARB252-8 features a dual motor structure that provides exceptional cone control and low distortion, even at higher excursion levels. With a maximum linear excursion (Xmax) of 1.3 mm and a displacement volume (Vd) of 2.6, it is capable of producing surprisingly authoritative bass. The driver offers a sensitivity of 77 dB SPL (1m/2.83V) and a total Q factor (Qts) of 1.74, indicating a design optimised for sealed enclosures where it can achieve a -3 dB point of 128 Hz. The 8-ohm impedance and 20-watt power handling make it compatible with a wide range of amplifiers, while the low voice coil inductance (Le) of 0.09 mH ensures clean, detailed response. With a mounting depth of just 29 mm and a cut-out diameter of 20.8 mm, this driver is a superb choice for achieving deep, controlled bass in the most challenging of spaces.
