@scottwsmith - as a general "rule of thumb" you could use any speaker that has either
1. a completely sealed enclosure
2. a bass port located in the front of the enclosure
Of course this is not definitive, but as a "guideline" it eliminates rear ported enclosures which are designed to have space behind them
Some e speakers with a downwards firing port in the bottom of the cabinet may also a good cabinet.. But this may only be true in some cases - t's a case of listening to them.
Hope That Helps - Steve
