Well their spec say so, but their recommended dsp settings are telling a different story.

Yea the infinite 8 was not my idea or my doing. Please see this diagram Timebomb. With the panel connected to the magnet, that should work, Also the panel is not on the side of the box in the diagram. Im tempted to give it a try.

What about water cooled magnets?
Use those CPU radiator thingies. |

With regards to fans and heatsinks, that's one for Reay at NCA or Phil B to discussā¦
I still think it's a waste of time without doing some serious maths to prove it's going to make a big difference to the amount of power compression in the cab. It's a very small, sealed chamber so it's going to be hot regardless. When I looked into this years back, it wasn't possible to get a decent thickness pipe with a suitable bend into the pole piece in the chamber as it's already so tight to load the drivers. You'd also need a solid core to be worthwhile, and a properly machined finned heatsink in the mouth of the cabs. Owning Psyco Subs with the heatsink in the same position, it can also cause other issues if you're using the boxes outdoors in direct sunlight as the heatsinks get very hot before you've even switched the cabs on. As for cost, water cut aluminium plates plus finned, properly attached sinks will likely not be that far off the cost of another box, which also gives more flexibility in futureā¦
Haha, I don't think that a radiator assembly would stand up too well to being shifted about!
DSP settings provided are for use with subs, so the crossover point is designed for the best transition between the two sections. I've run them down to 90Hz with a butter worth slope, playing pink noise for 10 hours, and they definitely have plenty of juice down there! Edited by toastyghost - 15 October 2013 at 3:24pm |

mmm, bit of pipe wrapped around magnet, two brass barbed fittings on back of cab - seems okay to me. It will be low pressure mind.

It would work better than ali access panels, how you connect it to the back plate/pole peice would be tricky, i think Void use thick copper cables which will conduct much better than air. Your still going to be limited but the surface area of the heat sink and the thermal transfer of the copper though, id have to check on the numbers but it could make a meaning full reduction in thermal compression. |

i like the water cooling idea!... couple of barbs out the back to simple low pressure pump to a bucket of water (with ice for really hot days). if that doesnt work then some one has broke physics!
you could hammer them hard knowing the hot water coming out the back will make a nice cuppa |

Somebody came out with water cooled lights, which I thought a crazy idea destined for someones death, but it still made production. High voltage and water .

Well, you would block or seriously reduce the v/c ventilation and cooling and also solid metal would have a better co-efficient.
