I have about 8.55 cubes (sonotube, tunning around 20-23hz?) and am looking for subs to shine in this airspace. Need to wire down to 4ohms to get my full 250watts.

I want to keep it under $100 shipped for the sub(s).

It's 18inch wide so my options are:

4 8s
2 12s
1 15
or
2 15s if enough airspace


Heres what I found so far:
