There is a new kid on the block who just proved that he belongs.MusicXtra that system looks killer. I wish that I could hear it.

Tnx for all the compliments.
The maximum output is +/- 127 dB for a single cabinet. |

Could be an inspiration to us all. |

Very nice work!
Do both low/mid drivers run up to the 1" xover? If so, I would expect some midrange interference in the horizontal plane.
Any profile pics of the HF throat?

Both mid drivers run up to 1 kHz, but the interference is no problem for the sound. I don't have pics of the HF throat, that's my secret. |

The drivers physical spacing and freq bandwith would cause problems for me...
Been there, done that... I saw/heard better results and wider bandwith with a longer low/mid array which used the same number of drivers. HF line does NOT have to be as long as the entire array.
My LA system was very difficult to array and is currently dismantled. It was used at a large outdoor venue about six times with good results.
I may re-use the drivers in PS boxes this time unless I can come up with a safe, simple hardware design to fly a vertical line.
However, I will say your rigging hardware is spectacular.

My line array is not a line source array, therefore the cabinets needs a vertical dispertion of 5 degrees and my system has 15 degrees.
But, for my gigs that's perfect because I didn't need a longthrow (up to 50 metres) system. Now I can use it from two cabinets per side for small venues and up to 6 (max 12 with a safety factor >10 for the rigging) for bigger venues. The rigging hardware cost me lots of sleepless nights but the result is a very easy working rigging. Now I'm thinking of a new version intergrated in the cabinet because with this version the brackets are separate from the cabinets and that is not perfect enough for me. |

Trouble is that the distance between the outside edges of the mid drivers will be some 400mm, which will cause lots of interference and lobing in the horizontal plane, with the result that the horizontal dispersion will narrow considerably in the upper midrange up to the crossover point. Boxes that use this configuration usually cross one driver out as the frequency rises so that only one mid driver is operating at the HF crossover point - even this will result in an asymmetrical dispersion at the crossover frequency. |

I know what you mean and I'm familiar with this but I measured a lot on this system, also with different cross-over points for both mid drivers. There was no difference in dispersion on different frequenties. I only needed less correction with the EQ in the DSP, in this 2 way configuration I need a low shelve for about 4 dB on 400 Hz. All the measurements and the sound where the same in the different configurations so making a three way system of it don't give me any advantage. Don't forget that both middrivers are placed in a short 120 degrees horn. |
