DSA215-PR 8 "

Passive Radiator Aluminum ⌀20cm


A passive radiator aluminum membrane of good quality, designed to fit most of the modernization projects / repair speaker 20cm format.

It has a 11mm tour, allowing to emphasize the low end without distorting the dynamics of sound. It may therefore be integrated easily into evocative and ambitious projects pregnant.

Its design as much as its specifications make it a very suitable radiator with the DESIGNER series in Dayton Audio. This did however not stop to offer excellent performance with other models.

To facilitate integration of the radiator and quickly achieve the best sound, the DSA207-PR comes with M5 screws, which will add weight to the radiator. This configuration lowers the resonant frequency in order to promote the natural balance of bass.
