TSP have made bass reflex design easy.
D.B.Keele discusses a modern design "A New Set of Sixth-Order Vented-Box Loudspeaker System Alignments" using TSP, which you can find on his homepage:...
Although a horn can't be designed with TSP alone, these parameters can give you a prediction of frequency limits, as D.B.Keele has pointed out.
A short summarization you find in JBLs Tech Note...
Some JBL speakers can well be driven in a closed box as Zilch Labs have worked out. ;) Some theorie may encourage you.
