Since you are taking physics you are familiar with math, and if you want to take a crack at designing a speaker yourself, take a read on Martin King's site, great info. Martin has done some excellent pioneering work on resonant type enclosures (TQWP, MLTL, horns) and has created some of the most definitive calculations methods to design these types of speakers. For a small fee you can license his mathcad spreadsheet calculators, well worth the money especially considering the cost and effort that goes into building a speaker enclosure. I have designed three speakers using Martin's spreadsheets, one horn and two MLTLs, with great results. There are also a lot of nice designs that were developed using his software on the frugal horn site.
