Our passive radiators offer a solution for small space and low tuned applications where a ported (vented) enclosure would be optimum, but where space does not allow for the use of a properly sized port opening or port length. Our radiators offer the user the ability to tune their enclosure lower than conventional ported enclosures normally allow for, in less space.
To say it simply, A passive radiator takes the place of a port when there’s not enough room for one. If available space is lacking, but you are not willing to give up output or sound quality, a passive radiator may be the perfect option.
Our new high excursion PR now offers even more excursion capability, meaning more output in the same amount of space. These new PR’s are are built utilizing a large spider diameter, our new tall roll surround, and high clearance frame. This combination allows for more movement from the passive radiator without mechanical noise or failure. When running subwoofers that are capable of extreme excursion levels, it only makes sense to use passive radiators that can keep up.
Standard version features include: 15″ 6 Spoke high excursion aluminum cast frame – Black 15″ rubber mounting gasket Rear mounted stud for weight adjustment 10″ progressive roll poly-cotton spider Kevlar impregnated pulp cone body 1.5″ tall roll rubberized foam surround
They are manufactured to the strictest standard, and guaranteed to last. Hand built in the USA!

Enclosure Recommendations: Passive radiators are recommended to be used as a replacement for a port. You should generally use about the same or slightly less enclosure volume with a PR that you would with a port. PR’s can be used to achieve a low tuning in a moderate or small sized enclosure by adding weight to the rear. The more weight that you add, the lower tuning that you’ll achieve.
The only limitation will be the upper tuning frequency. Depending on the size of the PR and the internal volume of the enclosure, there will be a maximum tuning frequency limit. For help with this, please contact us directly.

*The rear stud of the PR is left long, to make it easier to add additional weight to the radiator. The rear stud will travel beyond the rear edge of the frame during normal operation. If a shallow mounting depth is needed, this stud can be trimmed shorter. Trimming the rear stud can allow for the PR to be installed at the mounting depth of the frame only, without any additional clearance needed.
