DSA270 PR-10 "
Passive Radiator Aluminum ⌀25cm
A passive radiator with aluminum membrane of good quality, designed to fit most of 25cm speaker modernization projects or repair.
It has a 11mm excursion, allowing to emphasize the low end without distorting the dynamics of sound. It may therefore be integrated easily into ambitious and powerful speaker projects.
Its design as much as its specifications make it a very suitable radiator with the DESIGNER series in Dayton Audio. This does however not stop the radiator 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.
