[* General Rule*- Subsonic Filter set to 1/2 Octave below Recommended Box Tuning HZ? Confused...]

Understood Joe and thank you for the response it's much appreciated.

 

Box tuning is 33hz, I've used the DD-1 to tune the amp however I know this obviously doesn't cover everything as you mentioned. 

 

Additionally, in one of the videos of Steve I watched recently he was going over the importance of why you need a quality LOC, which I'm using an AudioControl LC2iPro, which I tapped some speaker outputs as my inputs into the LOC.  Steve mentioned that I believe (I could have manterrupted) that most amps "like" 5volts in from a LOC. I used a multi-meter to adjust gain on the LOC and was able to get 5volts finally right on the mark.  Did I understand this correctly? 

Thanks again for any help in advance. 

[* General Rule*- Subsonic Filter set to 1/2 Octave below Recommended Box Tuning HZ? Confused...]

Just to clarify...

 

The general "Rule of Thumb" is to set the amps Subsonic Filter to 1/2 Octave below Recommended BOX Tuning HZ? 

 

So for example, I have 2x Skar 12" ZVX12V2's in a Skar AR2X12V Dual 12" ported enclosure on a Skar SKv2-3500.1D amp.

 

The Box's tuning frequency per their website is 33hz.

 

So I would tune the subsonic filter to around 33hz - 1/2 Octave, being 24.75hz, correct?
