what is the load likley to be on the 8r ciares after horn loading has occured in the punishers?
any ideads? ------------- n^2 modulo -P = number wang |

Hello VPAS, Hornresp indicates 5.0 acoustical ohms X 0.2763  Hope this helps!

| Is that for 4 ohm drivers? I've been assuming a 10r load per cab when loaded with 8r drivers. |

that what i was thinking which would be beneficial if i go with the i-tech's because of the output drop between 4 and 2 ohms, mite be able to squeeze enough power for 3 a side ------------- n^2 modulo -P = number wang |

Hi guys,
The plot I posted earlier was for the acoustical impedance of a Punisher loaded with the Ciare 12.00SW 8-ohm driver... Here is what Hornresp says about Acoustical Impedance under the help menu...
  Hope this helps!

Hello ToastyGoast,
Your pretty close to being correct if you have 8-ohms figured into your assumption (8 + 1.3815 = 9.3815)... The actual RE value for the Ciare 12.00SW 8-ohm coil is 6.73-ohms...

I think the bit we're interested in is electrical impedance.

Here's your bit... The SPL Response can be seen http://www.speakerplans.com/forum/forum_posts.asp?TID=11044 - here ...

Nice one. (don't why I invloved myself in this thread, anyway...) Is it possible to change the y scale so it only reads 0-20 ohms? bit hard to read it as it is. ------------- http://dancomsound.com" rel="nofollow - http://dancomsound.com |

alright mate,
Search the forum a bit, i always thought the 8r ciares ended up showing the amp 6r on a punisher because of the way the driver is loaded, so 3 in parallel would be 2r shown the amp.

Hello Matt,
I could be on the wrong page here,...but I'd imagine that it would show the amp 6.73 ohms NOT including the insertion loss of the speaker cable...

Hello sondsystemdan,
Even though it would be nice...I don't think that feature is available within Hornresp...

I think its possible.You could always export the data and use excel anyway.

| so if you had 2 punishers running in parallel what would this be |

I've been working off the rough assumption of 5 ohms, if they're loaded with 8 ohm Ciares. |

| will most amps run stable at this |

I've only run them off Infinite 8v2, and briefly from a bridged QSC RMX4050HD which just wasn't enough juice.
It's above 4 ohm stereo, so I don't see why not. Best to get confirmation from someone else though. |
