I "think" I have the gains set right.
It didn't change the frequency response, however.
I'm not running any EQ and have all other speakers/subs off.
The response is flat from about 150hz down to 35hz then starts rolling off evenly but quickly down to the lower limit I measured which is 10hz.
With the gains set the way they are now (all the way up on the INUKE and +6db in the AVR) I am able to set a LS12 @ 20hz @ +6db and a PEQ @ 20hz @ +6db w/ Q=2.
This gets me flat to 20hz but from 20hz down to 10hz again it rolls off evenly but steeply and I lose 15db from 20hz down to 10hz.
I run the REW sweeps at -20db on the MV and the clip lights seldom hit above -24db for the sweeps.
No matter how much I turn up the overall gain though, the frequency response isn't changing - just everything gets louder.
So correct me if I'm wrong, but unless I can find a way to EQ and "Boost" under 20hz, this is pretty much as good as I can get, right?
I could go more than 6db on the LS12 and the PEQ but to me, that seems like an awful lot, and what I really need to do is boost 15hz if there is headroom in the amp and if it won't make the driver go past xmech or heat it up too much at my normal listening levels of -10db.
I was already happy with my Epik Empires from 25hz up and still need to use them anyway to have a perfectly flat response with no EQ necessary above where the response starts rolling off so I want to somehow set these new subs up to where they perform best under 25hz and I don't really care what I sacrifice above that, unless me being so new to this is obvious and you're thinking I'm wrong and don't know what I'm talking about and missing
That wouldn't surprise me.
I hate how these roll off so quickly - exactly as the Empires do. I just must have absolutely NO room gain. The roll off is so smooth it looks like an outdoor GP measurement. I just wish it wasn't so steep.
I did notice in the waterfall and Spectrogram I have a LOT more energy below 20hz than I did with just the Epik's and DefTech's so I feel like there may be more these new subs can offer, but I think the only way to get it (as far as I know at least) is to learn one of the tricks to somehow boost the EQ below 20hz.
Am I on the right track or totally off the rails?
