THere's also TL (transmission line), ABC(I'm still not too sure about the performance of this one), and horns (but horns could very well be just a part of TL)

Nope...

There's plenty more :)

As for bandpass, there are 2 basic types- 4th and 6th order.

The 4th order is basically a sealed subwoofer with an acousti filter in front of the driver (port). 4th order has very good transient response, also very nice power handling.

The 6th order is like the 4th, except both chambers are ported. 6th order has poor transient response

Hmm, there's also Passive Radiator systems, Transmission Line, Dipole, Aperiodic, Dual chambered vented, isobaric, horn, inverted horn, tapered quarter wave tube...

actually, most of the bandpass inshows that I've seen had large, short ports. It might only be there for show, but that's what I saw.

You could play around with some designs in winISD and see what you can come up wiht.:)

Most of the bandpass boxes I've seen have the front area with plexiglass sealed and the sub area ported.

+ compound isobaric, folded horn, 3 chamber 6th order bandbass, and quasi 6th order bandpass...all I can think of :)
