Right now, while on sale for $500/ea, the Outlaw Ultra-X12 is probably the best deal on a well designed "serious" sub!
However, for what you are describing, the RSL Speedwoofer might work, but runs $400 each.
The Energy ESW-C10 is a pretty impressive 10" sub - especially if you consider how small the package is!
For a ported, it is compact, yet still pretty effective.
This is no longer produced - Klipsch bought Energy and discontinued their subs (except the sub in the Energy Take System), but here is one being sold on Ebay. If you bide your time and keep your eyes open, I am sure you will find another:
