Accuton ASP250 Passive Radiator

The Accuton ASP250 Passive Radiator is a premium audio component engineered to deliver exceptional low-frequency performance without the need for a ported enclosure. As a passive radiator, it replaces conventional bass reflex systems, offering a cleaner aesthetic and eliminating port noise while maintaining impressive bass extension. This 279mm driver is the ideal solution for audiophiles and custom loudspeaker designers seeking deep, controlled, and articulate bass in sealed cabinet designs.

The ASP250 excels in high-end home audio systems, studio monitors, and bespoke subwoofer applications where space and acoustic precision are paramount. Its ability to handle significant air displacement makes it perfect for both compact and medium-sized enclosures, providing a seamless, natural low-end response that complements any high-fidelity setup.

Technically, the ASP250 features a remarkably low resonance frequency of 24Hz, enabling profound sub-bass reproduction. With a maximum linear excursion of 16mm, it can move substantial air volume with precision. The total Q factor of 0.33 ensures tight, well-damped bass, while the equivalent volume of 131 litres offers flexibility in cabinet design. The 8-ohm impedance and 7.4-ohm DC resistance integrate easily with most amplifiers. Built with Accuton’s renowned craftsmanship, this passive radiator guarantees long-term reliability and sonic accuracy.

For those who demand the deepest, most controlled bass from a sealed enclosure, the Accuton ASP250 is an uncompromising choice.
