What passband are you running the Punishers? You have mid tops that are designed to reach you subs. I would get rid of the Punishers and get some more Psychos.

An Infinite 8 will actually do it's rated spec for the full time you run it, hence why you've cooked the coils. The drivers in that cab simply cannot take that much juice and you're wasting your time trying to gain an extra dB as already mentioned.
I'd also strongly recommend not using them with other boxes unless you're measuring to get the settings bang on - you're likely coming up against phase or delay problems and cancellations will make you run both sets of subs harder to compensate, risking further damage. More cabs, or different cabs is your best option. Edited by toastyghost - 15 October 2013 at 2:24pm |

Thanks, I have read about these, you can find them in old T.V's and computers. Do you fit the fan on the inside and have the aluminium rivets facing outside the box. I am hoping to avoid using one of these if i can. Will the science only work if the aluminium plate has rivets to increase surface area? Apparently the Lab Horns have alu plates, Cant find mush info explaining how if functions. Have a look at this simple sketch i did. Cheers  |

+1 , why feed them with 1kw, if you know they dont like it/ are not able to take it? 1 kw instead of 600w will give you not even 2 db more, probably about 1 db with that power compression! is it worth it?

Hi, I think we have v2 drivers as we bought them after 2005. The plans should have been v2. i like to run the punishers at 2 cabinets on a bridged 1600 or 2600 amplifier 4ohms. Either Matrix Quantum 1600 or Peavey 2600 4ohms. The Peavey only produces 2600 at 2ohms from what i remember. Matrix produces 1600 at 4ohms bridged NOT 2ohms. The cabinets were run from a void infinate 8 at 2ohms. NOT my idea and it wasnt me how wired it. The cabs were running for over 24 hours and some now do not work and we have replaced some of the cables inside. I am not too worried about the old cabs as I am looking to build 2 or 4 new cabs with aluminium plates. Below is a picture of our stack. Look out for the GREEN punishers.   |

Something like that! While ali doors would no doubt help the thermal gradient from driver to outside world I do have to wonder how much the air in between becomes the limiting factor. A lot of void cabs have heatsinks thermally connected to outside world where it matters I think? |

Realistically a Punisher can't take more than 600w before thermal compression takes over, and adding a heatsink is probably only going to get you a dB or so more output for a hell of a lot more effort in the build. Maybe even less if you don't attach it to the pole piece.

Have you got V1 or V2/V3 puns, and which version drivers have you got? The V1 drivers made for the V1 plans tend to overheat quite often. The V2 driver fits into the V2 and V3 plans, it is slightly better with staying cool. however its not perfect. Ive been using puns for 3 years now and never blown a driver. What amps and processing/filters are you using?
how many puns do you have and how do you stack them? upright? laying down? Ive read somewhere that stacking the cabs upright makes the drivers get hotter than normal, not sure how much truth there is in that but maybe you have experienced the same problem? |

Those "OldSkool" days when we looked at a job, quoted, telling the client what it would cost and apposed to being asked to do job that i would have charged £1200 in '95 (when derv was 34p a litre) for £400??? That angle??? I like that angle!!! Hence I go out with huge rigs now, like this stadium filler :-  Driven off this powerhouse :-  I'll wager that job was worth a lot money than most jobs punishers get used on!!!  |

I take your points Mr Shag, seems I come from a different angle.

Whilst I agree in princiapal, main reasons for not using more boxes are :-
i) You don't have any more! ii) you can't get any more in the motor! iii) you don't have amp capacity for more boxes... iv) given their budget they are bloody luck to have ANY!!! Most time more than one of the above apply!  |
