Most people use a rule of thumb that essentially says high Qts, low Fts speakers go in sealed boxes and low Qts, high Fts speakers go in ported boxes. I prefer to use bass reflex, and the reasons why are discussed in the threads called "Acoustic Suspension vs. Bass Reflex" and "Pi Alignments compared with B4, C4 and QB3."
