T60 High-Pass

#1 Post by PrismAudio » Fri Mar 24, 2017 11:03 pm

So ive recently added 2 more tubas to my rig and ive got to say the bass response is disgusting in the greatest of ways. I only do sound for electronic music events.

99% of the time i have it set at 27hz on a 48db slope. however at the most recent past event i set it a 20hz which was pretty fantastic when a track was played that had that great big low end. The drivers survived the show so all good there but i'm wondering if i'm causing damage to the drivers
My Current Rig:

4 - Omni 12
8 - J-Array Omni 12
6 - 2x12 Tuba 60s

DBX Venu360
Behringer XR18
3 x QSC PL236
3 x QSC PL325
1 X QSC PLX2502

IDK, but if you bring that rig to the Hat during Ash's Easter show we can combine our 2 rigs for some real awesomeness :chainsaw: !
Built:
17" width 10" driver Autotuba
2 x 29" width dual Lab12 Tuba60
6 x DR250 2510/asd1001
In progress:
2 x DR250 2510/asd1001
For best results, point the loud end of the array towards the audience

To have the same level of driver protection with a 20Hz high pass compared to a 27Hz high pass you'd have to halve the voltage limit.

Just out of curiosity, would the OP be better off setting a 24dB/oct @ 25Hz? Where would you recommend he high pass at, and at what slope?

The recommended high pass is 25 to 30Hz, the ideal is 28Hz, if you have the ability to be that precise. The higher the slope the better.
