Ok Sh**t... Wrote a rly long detailed response and reload the page and all is gone...

But happy to tell more this time a bit shorter haha

Dutch based and I build as a hobby a Soundsystem with my friends/crew.

Currently still at a early stage.

Tops: JBL HLA 4895 x4 so currently run 2 pairs in stereo but planning to get more potentially in the future.

Amps are all Crest CA but also a few Crest pro series (old once).

DSP are London soundweb Blu series but also got a Xilica XP4080 and a XTA448 not yet fully decided what to use in the filed but tend towards London soundweb atm.

FOH mixer: Midas U16

System mainly used for electronic music anywhere from slow to very fast (BPM in the hundreds) both low and high distortion music.

Subwoofer section is atm still fully missing which is why I am asking here because I was very happy when I heard the old bDEAP subwoofer Tom designed before the BC series.

The combination of High sensitivity and directivity without the need to use cardiod... Makes me especially intrested into this design besides the fact that I found the sound characteristic the last time I heard them very convincing them being able to play quite high having for my oppinion a nice transient response and "kick/punch" characteristic (ofcause not unique but still). And the distortion characteristics if I remember where also rather nice not being high especially when crossover the subwoofer somewhat higher.

So obviously I can't afford due to it being a hobby besides UNI to buy real BC subs and bDEAPs being not available atall in Europe knowing only a single person who owns them personally.

So because of that I look for plans simmilar to these designs. I like the fact that the Bdeap used 12 inch drivers with the only negative aspect being that they are not designed to be layed on their sides like the BC215. (Because the JBL HLA are quite big so I need a bit base to place them on)

So anyways I hoped that maybe here someone was able to design a subwoofer of simmilar character that he might be willing to share with me because my personal simulation skills in AKABAK... Are still quite limited and I wouldn't know how to model and design subs like these.

Hope this answers some of ya questions if not... please feel free to ask.

I'm not sure this has been cited in this thread but BDEAP clones were done by members more than a decade ago.
