I do actually have the plans for these, have had them for years..

I never really build one for a few reasons, mainly because I wouldn't be able to get the adjustable baffle to sit tight..

Being a bandpass box it does suffer from the common problems - Limited bandwidth, out of band noise, higher group delay etc.. Using good crossovers and strong midbass drivers are essential..

Thats not to say that you can't get a bandpass box to sound good. (while giving you the SPL gains...) But an individual design for the speaker would be more ideal.. - I'd start by measuring the T/S specs, then design the box using CAD (by that I do not mean see what the program cranks out when you first enter in the specs, I mean look at all of the graphs and tweak the numbers until I get a suitable alignment). Then I'd tweak the port lengths and box volumes while doing listening tests.. Getting a bandpass box sounding good is not that easy..
