Enclosure Details
1. Parameters listed are for conventional applications only, further assist please call Tech Audio Support 1-800-876-0800 ext. 2032.
2. Volumes given are NET Box volumes, speaker and port displacement are NOT calculated into the volume of the enclosure, you will need to add these volumes to calculate
GROSS volume for the enclosure.
3. The approximate volume of air displaced by the port can be calculated by using the square port area (H x W) times the port length and then divide by 1728 to get cubic feet.
4. Please call Tech Audio Support 1-800-876-0800 ext. 2032.
* SPL usage only! Not rated for continuous use at this level.
** For SQ (sound quality applications) amps should be between Pe and Peak power ratings.
*** Subsonic filters should always be used and adjusted specifically for vented box designs.
