Enclosure Details

1. Parameters listed are for conventional applications only, for further help please call Tech Audio Support

2. 1" MDF is recommended.

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.

*** Sub-sonic filters should always be used and adjusted specifically for vented box designs.

NOTE: The woofer must face up or down only, especially in sealed enclosures.
