Is the internal volume of the X15 aprox 6 cu. ft. Also, if I needed for some reason to build my own crossover, have the specs been posted here before. Thanks |

A crossover schematic for the X15 has been posted (not sure whether
this if for the 1" version though), but this board has suffered under a
hack and the design is no longer linked from the forum. Martin |

| B.T.W. I have finished my two way (SN15MB + BMD450+ PH220) cabinets and installed crossover that sounds best is ridiculously simple (6db/oct @ 2000Hz on bass and 6db/oct on 5600Hz on High-s)… P.audio PH220 horns have rising curve from around 5000Hz to lower freq. and this combination makes thing pretty flat.. |

Could you use simple op amp circuit to equalise response and make the HPF down near where the LPF is ? Im unsure of what horn type the PH220 could be CD i guess. If you REALLY want you can do lots of things to try and get best results from these horn + 15" combo http://www.pispeakers.com/AES_v31_n6_p408.pdf - Improvements in Monitor Loudspeaker Systems ."

Have you used these yet with your Bandpass-Horn, if so how do they sound together |

@ tbmike, though OPamp filter circuits are great for DIY audio at home,
in pro-sound situations one needs something more rugged, generally with
balanced inputs and outputs. My only concern would be, whether the driver lives with a first order crossover. Most crossovers use a high pole for the first filter section and another set closer to intended x-over (CD horns only). Certainly seems like a very simple crossover and if it works it would be a gret budget alternative. Is the posted x-over for the 1.5" version? Martin |

With my bandpass horns I am using big 12" + 2" horns (pretty like MT122 but with single 12") .. These 15" + 1" cabinets are already instaled in club and bass is enforced with dual 15" bass-reflex cabinets (also designed by myself).. Combination sounds great. I haven't digital camera jet ..but i will borrow some from friend and take few photos. |

Bit off topic but any chance for the X12 crossover schematic ? Tried a couple of time to get in touch with proaudioparts by sending them an e-mail. Got no response so I'm not counting on them to deliver the crossover when it's available. Guess I'll have to build them myself ... If only I had the schematic. regards, Jogge ------------- Always listen to experts. They'll tell you what can't be done and why. Then do it. |
