I have Arc ultra, Sub 3 and 2 Era 300.

 

I ment isn’t it a potentiometer like others.
I am not searching for the hard cheap bass heavy sub. More like low deep “umph” a bit that u can feel. 
no doubt the Sub is powerful but not enough for me. 
Is it worth buying one more sub? 
 

I am how ever used to a car sub with 1200W rms…

and that you can feel, under 15hz 

 

It sounds like you are looking for hearing damage levels of output.  Take it from someone who spent a good part of his youth standing 10 feet from giant Marshall stacks at hundreds of punk shows; hearing loss just isn’t worth it.

    15 Hz is out of the response range of most subs.

    Also there is very little source material that has content at that frequency.

     

    I built a fancy setup that included a dbx subharmonic synthesizer feeding Klispch LA Scalla speakers, through a kilowatt amp, that setup was pretty good down to 20 Hz. The dbx used a dsp to analyze the incoming audio, generate subharmonics and either inject them or send them to a dedicated output. Sounds like what you are looking for along with a custom sub designed to reproduce frequencies considered below the normal audio range.
