Dayton Audio DSA115-PR

Radiateur Passif Aluminium 30.9Hz Ø10.2cm

Dayton Audio DSA115-PR Radiateur Passif Aluminium 30.9Hz Ø10.2cm

The Dayton Audio DSA115-PR is a passive radiator that can be used in a wide variety of installations, whether as a speaker or as a replacement for a similar defective model. A built-in grounding disc ensures that the passive radiator will fit most applications, and an M5 thread allows you to add weight for a precise fit. The aluminum diaphragm and rubber suspension allows for a long linear excursion, while providing true ruggedness for long life.

How a passive radiator works

The passive radiator (or passive loudspeaker) fits into a box with an active loudspeaker. This passive radiator, although it may at first glance look like a "classic" loudspeaker, does not in fact have any engine parts. Thus, its design does not include a coil, magnet and power supply. In the same way, it will not be electrically connected to a power amplifier.

To diffuse sound, the passive radiator will use the air pressures and depressions induced by the active loudspeaker in the cabinet to vibrate its diaphragm and restitute sound, thus providing deep bass. Its resonant frequency is determined by its mass and contained in the cabinet. Therefore, on many models, its resonance frequency can be varied and tuned to the speaker by adding mass.
