if you have a speaker spec sheet i can load it up into a program to get the proper chamber volumes a port size.

it's hard to beat a properly tuned ported enclosure for sound quality and spl. the single reflex bandpass has similar qualities, but really needs good crossover points. it also can look cool as well as protect the driver.

i personally like to load my speakers iso-plane (iso baric load where they are coupled w/ a cavity under plexi). the 2 drivers face up, but physical characteristics are like a clamshell, but you get to see both drivers cones and it takes up less useable space.

i've used sealed, ported, single relflex bandpass, and dual reflex bandpass and all have their applications. unless you plan on using more drivers for mid bass along w/ mid range drivers i would stick to a standard sealed or ported exclosure for sound quality as well as ease of construction.

hope that helps.
i want to build one for a alpine type r 10 inch sub and its 2ohm if that helps.
