The BPA (Blue Planet Acoustic) Trio kit uses different drivers than the original Trio 15 from Pure Audio Project. The crossover networks of both speakers are not public.
However, you easily can build your own clone. Use two Eminence Alpha-15A per side and you indeed get a speaker with a sensitivity of 94 dB that goes down to 40 Hz (-6 dB). The filter can be derived from Martin J. Kings paper: http://www.quarter-wave.com/OBs/OB_Design.pdf
Once you have decided on baffle dimensions and fullrange driver, open a new thread to get help with the final crossover design.
