Dayton Audio DSA215-PR 8" Designer Series Aluminum Cone Passive Radiator

The Dayton Audio DSA215-PR 8" Designer Series Aluminum Cone Passive Radiator is a premium solution for audiophiles seeking to extend the low-frequency response of their speaker systems without the need for an additional amplifier channel. This passive radiator is designed to replace a port in a vented enclosure, offering a more flexible and space-efficient approach to bass reinforcement.

Ideal for use in compact loudspeaker designs, home theatre subwoofers, or custom audio projects, the DSA215-PR excels where traditional ports would require excessive length or where a sealed enclosure lacks sufficient low-end output. It is particularly well-suited to satellite-subwoofer configurations and high-fidelity stereo systems where controlled, deep bass is desired.

Engineered with a rigid aluminium cone and a durable rubber surround, this passive radiator ensures precise, low-distortion movement. The steel basket provides robust support, while the 11 mm linear excursion (Xmax) allows for significant air displacement. With a resonance frequency of 25.6 Hz and an equivalent volume (Vas) of 36.8 litres, it integrates seamlessly into the Dayton Audio Designer series. The 178.1 mm cut-out diameter and five mounting holes simplify installation, making it a practical upgrade for serious audio enthusiasts.
