I've tested the cab 2 days ago, results where encouraging but it needed more bracing in the mouth. For me they go low enough, I used 24dB BW @30Hz, HPF and 24dB LR @80Hz NOTE: those filters where just figured on the go, so probably not optimal. For amplification I used one channel of a CTS-3000.

If possible I'm going to add some bracing in the next coming weeks and test again.
Also using the 21SW152 for the cab is on my mind.

Those components are some powerful players smitske96. Does anyone have any background info on paraflex enclosures? When searching, paraflex seem to be the name of whatever hybrid of series/parallel BP6, transmission-line, tapped horn, planar wave or reflex one can come up with.

About drivers, if a Paraflex is anything like series BP6, low Qes is critical to low-frequency performance. In simulations I gained approximately 10Hz of extension (40Hz-30Hz) going from 21SW115 (Qes of 0,39) to 21SD115 (Qes of 0,24), in a 300L series BP6. Try to sim it if you haven't.

Yes but using the 21DS115 in the type-C the width of the cabinet would become 81 cm.
Using the 21SW152 the width of 61 cm can be used due to the lower Le.

Until now I still don't know which driver to use. price difference is about 100 euros here.
