Enclosure Details
1. Parameters listed are for conventional applications only, for further help please
call Audio Tech Support.
2. At least 0.75" MDF (Medium Density Fiberboard) is recommend for any XTRPRO
enclosure.
3. Recommended enclosures are NET box volumes, speaker and port displacement
are calculated into the volume of the enclosure, you will not need to add these
volumes to calculate GROSS volume for the enclosure.
Notes
* Due to the high power capabilities and long excursion of the XTRPRO woofers, the
Thiele/Small Parameters were calculated and measured using a Klippel analyzer
system.
** Energy Bandwidth Product (EBP) is determined by the following formula Fs/
Qes=EBP. EBP values of 50 and lower suggest a sealed enclosure is best, 50 to90
means the subwoofers versatile and 90 and above mean vented Enclosure is
recommended.
*** Subsonic filter should always be used and adjusted specifically for vented box
designs.

ENCLOSURE RECOMMENDATIONS
Enclosure Details
1. External dimensions calculated for 3/4” building material
2. Includes speaker displacement
3. Volumes given are net tuning volume
4. Enclosures include a minimal amount of damping material. Just enough material to
line the inside of the enclosure is required.
