It never end if this goes on. I recommend you this sub which is superbly good for your requirement. It chews the highly acclaimed Fathom F113 sub for breakfast.

It goes loud and deep (9Hz).  It's Paradigm Signature Sub25

It's a reference to the degree of volume setting. Anything above 12 o'clock is more than half the volume.
