3rd Order vs 2nd Order: Folded Horn vs T-Line

This video is the second in a Playlist called Counting Acoustic Orders. This video shows you how I learned how to count subwoofer enclosure orders. I discuss the differences between multiple subwoofer enclosure models; based upon which 'acoustical' order they were designed after.
This video features:
* 2nd Acoustical Order: Infinite Baffle
* 2nd Order Enclosure: Sealed Enclosure
* 3rd Order Enclosure: Folded Horn
These interesting enclosure design styles may or may not have been something you or someone you know have used in the past. This series is meant to get a conversation started and enable us to teach each other in this field of acoustics.
