NOTE:
Vb is the gross volume, which is the TOTAL internal volume, before any speaker and/or port displacement.
All external dimensions were based on the use of 3/4" (1.90cm) materials.
NOTE:
When using enclosures other than recommended, call Technical Support for correct application.

NOTE:
An IB enclosure design represents an application where the
compliance of the air volume within the enclosure is greater
than the compliance on the speaker’s suspension (Vas). An
infrasonic filter is required for reliable performance.

IMPORTANT:
Take care when installing your baffle board. Air leaks
can cause significant performance loss.The more care
you take to ensure the cavity area and baffle board are
sealed will yield optimum results.
