DAYTON AUDIO DMA105-PR Radiateur Passif Aluminium 37.9Hz Ø10.2cm - avis - Il y a 1 avis.

Average.
A bit expensive for what it does.

The specifications seem to match the passive radiator with one weight and the mounting screw added, not without any weights added as the manufacturer claims.

I did no professional measurements, though, just testing with a cheap calibration mic and comparing the results with winsd projections for the box size and driver.
