Our passive radiators offer a solution for small space and low tuned applications where a vented enclosure would be optimum, but where space does not allow for the use of a properly sized vent. If you want to tune an enclosure to less than 25hz, and are having a hard time finding a way to fit the correct port area and length, then a PR would be the perfect answer to your problem.
Passive radiators come standard with a rear mounted stud for mass adjustments, but can also be custom built with front mounted studs for applications where quick tuning changes are frequently needed.
All PSI radiators are built using the same high quality moving assembles that we use to assemble our subwoofers, and are available by custom order with any of our custom options, including colored parts, custom logo, optional dustcaps, and more.
