FREEAIR MOUNTING
These specially designed PowerBass FreeAir woofers allow them to work effectively in infinite baffle ap-
plications. This does not mean, however, that the driver doesn’t require an enclosure. What it means is
that the enclosure can be of very large volume, such as a boat hull or car trunk. In these applications the
woofer needs a relatively rigid panel to mount to so it will not vibrate or reduce efficiency during operation.
Also, the panel should effectively “seal” the air behind the panel from the air in front of it. If your mount-
ing panel doesn’t meet these requirements you may need to modify it with bracing or consider building a
sealed enclosure using the parameters set forth in this owner’s manual.
Panel or baffle where the
woofer is mounted
The mounting panel should separate air behind the
panel from the air in front.
