There's also the Yahoo group Quarter-Wave (http://tech.groups.yahoo.com/group/quarter-wave/), where there is discussion of loudspeaker design, and the related website Quarter Wavelength Loudspeaker Design (http://www.quarter-wave.com/) where there is Mathcad software for loudspeaker design. Mostly for transmission-line designs. Seems to be good; but I haven't built any yet myself.
