Dayton Audio Epique E150HE-PR Passive Radiator

The Dayton Audio Epique E150HE-PR Passive Radiator is a premium solution for achieving deep, authoritative bass in compact loudspeaker designs. As part of the acclaimed Epique series, this passive emitter is engineered to complement active drivers in sealed enclosures, delivering low-frequency extension without the need for a port. Its primary use cases include high-fidelity home audio systems, custom subwoofer builds, and high-performance automotive installations where space is at a premium but bass output cannot be compromised.

Technically, the E150HE-PR boasts a nominal diameter of 139.7 mm and a resonance frequency (Fs) of just 30 Hz, enabling it to reproduce the lowest notes with ease. Its maximum linear excursion (Xmax) reaches an impressive 19 mm, while the displacement volume (Vd) is rated at 180.5, ensuring substantial air movement for powerful, clean bass. This passive radiator is designed to handle high-excursion demands, making it ideal for use with the Epique series active drivers. By replacing a traditional port, it eliminates chuffing and port noise, allowing for a more flexible enclosure design. With its robust construction and carefully tuned parameters, the E150HE-PR offers a sophisticated way to achieve deep, room-filling bass from a compact cabinet, elevating any audio project to professional standards.
