Yes i've cut the compression driver as shown in your threads
then i started with a simple condensator of 1.5mF, as i did with the bm 8
the sound was very aggressive, may be a bit more power in the low mid
but on voices, or flute , it is very aggressive with big pikes in the medium-highs
i've tried selfs to shut a bit the 12 inches around 1khz
i've tried 18db xover on compression drivers and some resistances to lower the efficiency
there is something wrong in this combinaison, still pikes on medium highs, and very disturbing on choirs and opera.
I didnt find the same smooth and details than with bm8
the bass is now very good, with combinaison of 2 sly 12 from perless on open baffle with active xover
could you send me the sheme you are using for this driver?
