Help finding a Mid-Sub

Not posting this because I'm too lazy to research, But I can't seem to find much in the line of a fair quality "Mid-Subwoofer." What I'm speaking of would not be a Subwoofer for home theater, but rather a separate Mid unit that will produce a very clean, tight, powerful and fast punch in the chest with music only. "Specifically Hard rock."

I have a good Subwoofer now for my home system and it provides those very low tones well, although it does not and can not thump a shot gun Mid blast in your chest. Something very tight and with zero reverberation is what I need, but so hard to find.

If anyone has any low to high dollar ideas either used or new I could use a starting point. Thanks.
