Enclosure
Details |
| 1.
Parameters listed are for conventional applications only, further
help please call Tech Audio Support
2. Recommended enclosures 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. Please call Technical AUDIO support for further specifications and
information: 1-800-876-0800 ext. 2032
* For SQ (sound quality applications) amps should be between
Pe and Peak power ratings
** SPL usage only! Not rated for continuous use at this level
*** Sub-sonic filters should always be used and adjusted specifically
for vented box designs
