Great to see how quickly you have put these together. You indicate that you havent used the BMS2236. From the foto i can see that you used the xt1464. Is that right? In adation i would like to ask where yo got the dcx464. BlueAran is soldout as is TLHP
The passive crossover they offer looks great. The reason i'm asking is that i am building a pair of pm60/90 and also want to use this driver horn combination. I could use a little help. I 'm using xilica xd processing an if you had a startingpoint for setting that would help.
The first prototype I built was with the BMS 2236 horn (I only redid the front baffle when I went with the DCX). I still have a BMS 4592 + horn and passive xo laying about if you're interested. I did like the sound but as I was planning to build 4 cabinets the B&C + XT1464 was just cheaper. I ended up ordering the XT1464 horns from thomann, the DCX464 from TLHP (it is currently in backorder both at TLHP and at the german distributor, but with the corona virus everything is on hold since the drivers have to come from Italy).
I also got the passive crossovers from BlueAran and they sound great. It wasn't difficult to cross the driver actively but being able to use a single amp channel / cable & connection panel just makes this a great option for me. I currently cross over between the XT1464 and PD158 at 600Hz, but found that anywhere between 500 and 650 works well enough. The PD158 doesn't lack clarity in this region at all, so I don't feel a need to go any lower.
Let me know if there's any more info you need. I can always upload some measurements or more pictures.
