where to buy audiocontrol subsonic filters?

[RJesus 10+ year member]

I just bought an audio control epicenter and it came with a 15hz subsonic filter.

So I'd like to replace it with a 30 something hz filter, any idea where I can order one at online?

AC has a wonderful website and it has tech info literature on that site also. here is the link below:

In that lit they tell you the about the different modules they can supply. All you need to build your own is a few precision resistors and a DIP header to make your own SS filter. I am sure they would gladly supply the simple math formula to you if you email them and ask. I think its the same formula they use for all they older discrete crossover filters they use to make over the years.

If you read this manual for the 2SX it tells you how to build your own PFM subsonic filter modules on the second page, labeled page 9....enjoy

7200 divided by the "frequency" you want will equal the "resistor value in kilo-ohms" and you must use 1% tolerance metal film resistors, soldered to a DIP header
