A good example is watching Everest, When the dark clouds roll in and lightning happens you can really feel the thunder when my subs are at -15, but then when the wind picks up -15 is too high because the non tactile bass is artificially too much to support the wind and needs to be at around -20 or so to be realistic.
My subs are on carpet with concrete underneath so I think I just need a boost at the very low end to pull off what i'm looking for.
I've never had tactile
like this before so i'll give minidsp a shot.
The miniDSP is definitely the right way to go here, but just for fun I will mention something else that you could try without a miniDSP. I can't remember what form of automated room correction you have, but several of them work in about the same way. They try to EQ your frequency response to be fairly flat and some of them, such as Audyssey, can provide control points all the way down to 10Hz.
Something you could try would be to calibrate your subs in the Standard 20Hz mode. Automated room EQ would stop setting control points where the subs roll-off by 3db. That would be right around 20Hz in Standard mode. Then, post-calibration, you could reset your subs to the Extended 16Hz mode.
In most rooms, you will get a fair amount of room gain below 20Hz, which room EQ may try to attenuate in order to achieve a flatter frequency response. But, you don't want a flatter FR. You want a low-bass house curve. Calibrating in the Standard mode, and then switching to Extended mode, post-calibration, would allow you to take more advantage of your <20Hz room gain, and should increase your <20Hz SPL.
The above technique might give you a more natural low-bass house curve than you have now, and some of what you are looking for, even without a miniDSP. Since you have REW, you would also be able to see exactly what is happening to your frequency response when you try this. Having access to a miniDSP may still be helpful to you, especially if you ever decide to play with BEQ (thread with description of BEQ linked below), but you might still enjoy trying this in the interim.
Edit to my previous edit
: I just realized that the App was mentioned in a previous post. I've never used the Audyssey App, but you could also try telling Audyssey not to EQ below about 20Hz (or 25Hz). That way, you could calibrate in Extended mode without Audyssey attenuating your room gain as much. You might enjoy trying both methods to determine which works better. In theory, the results should be similar, but theory trips us up sometimes.
