Speaker plans for Yorkville A215 and Com

Hey guys, I am looking into getting a Bass cab which will give a little more "punch" that the double 18" I have right now, I don't want a folded horn design since I don't want the bass to throw too far, I remember approx 20 years ago Altec had a double 15" design with curved edges which gave a nice punch when put together with a double 18 bass reflex but I can't find that design anymore so I am looking for a simple cab design which if I cannot get a used one locally then I can try to find the specs and make it myself? I've been told about these 2 below, anyone got speaker plans for any of these 2 subs please ro can recommend any other which will work for my application please?

Have a look around these sites-
wizardaudio.hu/hasznos.php
hornplans.free.fr/bass_sub.html

Thank you very much,those look like great forums for me but I am not seeing an "English" option on any of those 2 sites?

Don't know of an english one.......those are the best two though.

Strange, there isn't an option to translate those sites into English.

I think some web browsers can do translations. Mine can't so I am not that helpful, but a friend of mine has that option. Many of the plans are in english even though the sites are not.
