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 Volume 1, #24: "JBL's New Maximum Output Midrange/Low Frequency Transducers" (page 3).
The theorie behind is published in an AES paper (preprint):
D.B.Keele: "Low-Frequency Horn Design Using Thiele/Small Driver Parameters"

The frequency limits are related to a straight horn. With bends arise limitations. Dr.Bruce Edgar has made some investigations which are published in Speaker Builder 3/93 p.13. A legalized copy is on Volvotreters site with "The Monolith Horn, page 2":
