Filter settings??

[bhsaudio 10+ year member]

Yes, I am trying to set up my aq2200d and I have a few questions about the different filter settings. Amp is hooked up to a single DD 2512 D4 wired to a 2ohm load(2.43 to be exact). Sub is installed in a a box built at 2.0cf before displacement with 44" of port turned to 38hz. I know how to properly set the gain but I am somewhat clueless on what I should have the Low Pass Filter and Subsonic Filter set at. Bass Boost will not be used so its of no concern. If you could give me any kind of advice on the filter settings I would greatly appreciate it.

Subsonic filter set at?

If your sub box is ported you want to set the sub sonic filter at the highest setting. This clips all the hz below the your dialed setting, this is waisted energy that your sub can not process and will let your amp be more effecient. The Low pass filter does the opposite, it clips all the hz above the dial setting. You should start at 70hz and slowing increase it until you like the sound. 90hz is a text book sub setting but it is purely a listeners choice.
