RECOMMENDED ENCLOSURES FOR OA8, OA10 & OA12
OA8,
OA10
subwoofers are designed for
open air use but can also be
used in these enclosures.
Subwoofer Volume (liters/ft3)
OA8
15 / 0,53
OA10
29 / 1,02
OA12
use sealed enclosure
*** It is impossible to have a 44 cm port inside a 15 liter enclosure! If you want to use the vented box just cut the
port tube 2,5 cm / 1" from the back wall for a good function. Doing so the subwoofer sees the port to be longer than
it is because the short distance between port and back wall has an influence on the air flow through the port.
