is there any way using a combination of series/parallel wiring i can run 3 bins a channel without it being a 2.66 ohm load?? ------------- hell is just a word, the reality is much much worse! |

If you have 2 bins in series that are then paralleled with 1 bin, you have a load of 5.33Ω... however, you've got the power issue to contend with then. That is presuming that the bins are 8Ω. ------------- Chas n Dave : it's like Drum and Bass but with beards. E=mc² ±3dB |

not to mention that some of the amp's power will be split over the two series bins whilst the one in parallel will be trying to cope with the all the rest by itself! ------------- Time flies like an arrow - fruit flies like a banana! |

never mind the fact 2 of the drivers will recive more power than the third ------------- Disco Hire Wales |

well i suppose it depends on which has the less resistance the single alone driver or the 2 wired together... and yay tripple post ------------- Disco Hire Wales |

the single bin will have half the resistance of the two series bin so it will be stuck with most of the amp power. Not a good idea. Either only use two bins or get another to make four. Then wire them in series/parallel. ------------- Time flies like an arrow - fruit flies like a banana! |

so with the right amp choice with a little headroom it is a possibility or am i just going to blow a driver/amp, trying to build this system on a budget as i had to sell my last rig for financial reasons. ------------- hell is just a word, the reality is much much worse! |

What amp are you planning on using?

possibly a matrix xp5k not a 2 ohm stable one though ------------- hell is just a word, the reality is much much worse! |

hmm no easy solution i think the choices are drop 2 of the hd's to run two aside get another 2hd's get an amp that will run 2ohm stable or get a second amp to run 3 pairs ------------- Disco Hire Wales |

could run 2 banks of 3 in series 24ohm/2=12ohm and bridge the amp then your running 6 ohms a channel?

Thankyou Timebomb sounds perfect can't find the specs to the xp5k now so not sure what it would be putting out at 12 ohms? ------------- hell is just a word, the reality is much much worse! |

See what you mean its not the easyest amp to find specs for...id guess as its called a 5k thats not rated below 4 ohms per channel then its about 2500W per channel at 4ohms, wich is 5000W at 8 ohms bridge (if it does bridge)so say about 3000W at 16ohms bridge and 4000W at 12 ohms bridge which into 6 drivers is 666W each. ------------- James Secker facebook.com/soundgearuk James@soundgear.co.uk www.soundgear.co.uk |

so that should be fine across 6 pd154's then? :) ------------- hell is just a word, the reality is much much worse! |

Yeah would be about right id say, assuming that amp does what i guessed it does, might be an idea to PM andy and check.

good plan i think the amp will need to go back when i get it anyway it has a channel down so i'd best get in touch with him. Thanks for the advice ------------- hell is just a word, the reality is much much worse! |

I would seriously suggest changing the amp. Or send the amp back to matrix for a 2r update thingy. All this messing about sounds like a Carnival float... ------------- www.wedding-production.co.uk www.stage2sound.com |

Just what I was thinking. there's always the thing if the amp goes pear shaped you lose use of all the cabs too, (not good in a room full of punters) better in the long run to do it right the first time. Either buy two amps or better still buy two amps and another pair of cabs and be safe. ------------- Never criticise another man until you've walked a mile in his shoes.
