If he is I wasn't aware so I don't see how that statement is relevant. |

That is a bit of a stupid statement. Just look how many 'basic' point source cabs come with either built-in DSP, or external controller. Nexo PS15 is a classic example. Try use those without the controller. |

There's a large number of people who drink a certain kool aid about EQ, apparently it's the devil - nevermind that all of your high pass, low pass and other filters are exactly the same damn thing. |

I was being facetious. The whole ethos of designing and building cabinets that NEED EQ correction in order to make them usable is a joke.
In the context of using an instrument driver as a PA driver in a DIY box thats going to cost a couple of hundred quid to build to a decent standard and need a parametric EQ that costs at least as much again to get it under control?
How many of those boxes sound fine without it and how many of those are doing much more than acting as x-overs for use with optional bins or adding pre-emphasis to the low end or top end in certain applications as in the SX300 processor? How much noise do some of them inject into your signal chain?
Try using a PS15 even with the controller they sound like pretty much every 15"+CD Disco box... Awful.
The PS series are a good example of a bad idea though, without THE processor for the specific model they are little more than expensive firewood. The processor itself isnt cheap either and its not exactly a versatile device. The only saving grace of what Ive heard of the series is that the PS12 does sound very nice for stand alone tit-on-a-stick duty |

Highpass and Lowpass filters that are an unfortunate byproduct of the fact that nobody has yet built the 'perfect' audio transducer. VS. EQ that's necessary because nobody could be bothered to design a speaker properly or with appropriate components for the task. Its a breach of basic Engineering design principles. ( |

Remember driver oppposite phase of bass, BUT JBL-basses are out of phase! postitive polarity moves cone backwards, this can give issues with aligning with other cabs / subs, I think most other designs has bass at normal polarity and horn reversed, so notice phase if used with subs.

Strange! All the 2225s, 2226s & E-140s, E 130s, K140s I've seen are.
Perhaps aftermarket diaphragms can be the other way around. Always check, don't like JBL that much... |

[QUOTE=_djk_]Depends on your horn, 1Khz should be OK.
Is it safe to cross a 2446 this low? Thanks for all the responses. Edited by ychole audio - 31 July 2017 at 3:03pm |

JBL 4" diaphragms don't sound good crossed below about 650hz or so, even on a huge horn (2360 has a 300hz cut-off).
