A Few Words
About Enclosures
The enclosure or box that you
choose for your Power Series
woofer will define the sound that
will ultimately come out of it.
The size of the box and tuning
frequency of port tubes in vented
enclosures dictate the low-
frequency performance and
output capability of your system.
The flexibility designed into the
Power Series subwoofers lets
them make tons of bass in small
sealed, vented and bandpass
enclosures. They will also work
well in infinite baffle applications
where there is no space or budget
to build a box. Be aware that infi-
nite baffle or ”free air“ mounting
will reduce the power handling
