Work continues on the PA system for the school. I just finished the first main speaker this weekend so I wanted to test it out. I decided to pull out all 4 subs because I had never tested them all at the same time. Good fun ensued :)

There will be 3 more main speakers, so it will be more balanced. As it was in the video the subs were not run at full power and the main speaker was being pushed a bit harder than I would like for long periods of time.

The volume was immense. I estimate 132 dB at 1 meter on peaks, not even at full volume. For scale listen for the conversation in the background. That was my friends watching, from directly behind the camera about 4 ft away. It is usually difficult to hear what they are saying. The SPL meter showed it was about 100dB at the camera.

The mic is on the edge of clipping throughout the video, so if you hear distortion that is what it is. Also, if your sound system doesn't go down to at least 45Hz well then you are not hearing all of the content those subs are putting out.

Hardware:
1 DR 250 top speaker (Beta 10a and ASD1001 compression tweeters)
4 TH18 tapped horn subwoofers (open source diy design)
3 XLS1000 Crown Amps
1 dbx DriveRack PA+

Everything will be painted black all at once when it is all built.

P.S. they Kony thing in the background was unintentional haha...
