getting back to the WLX, i keep looking at the specs and find them hard to belive, given the layout of the cab , and its size ETC
does anybody else want to comment on that, Cerharden, centauri , deadbeat, minimaxil, nineleaves anyone?????

Can someone explain why a letterbox shape is used rather than simply a circle or smaller diameter than the driver? surely that would load the driver more evenly.
Also, taking that idea one stage further, has anyone ever made a cab where it has a circular exit from the front chamber, but turned this into a flared port (i'm thinking like a velocity stack on an inlet manifold here) with a view to smoothing the coupling into the main horn.
Or is this just adding a an unneccessary horn within a horn?

The letterbox is effectively the throat and it's easier when building a folded horn to expand from a rectangle than it is from a circle. Some creative fibreglassing might be the answer, but it would have to be very heavily braced and damped to prevent losses and/or resonances due to the high pressures involved at this point in the horn.

I see what you mean by effectively starting the horn / throat with a square - but as it is in effect suspended and not part of the horn then why not just make it circular? |

It's not suspended (if it looks like the WSX plan I saw a while back) - the throat is the rectangular letter box and all expansion takes place from there. To expand from a circular cross section whilst transforming into a rectangular cross section (as you have with a folded horn) is more complex to achieve with plywood.
