effect of heat in chamber

Reality Sound wrote: When or how do you determine when a heat sink is necessary in a cab? All the newer CV cabs, B52's, and LAB horn use heat sinks, why not the 1850/186 horn for instance?

Because they're DIY

The Lab horn is DIY with heat sinks. The question is, under what circumstance does a heat sink become necessary?
I used to dj at a club that had a couple B52's, and used to spank the piss out of them for 5 hours straight and the heat sink wouldn't even get slighty warm.

What heat sinks does a Lab horn have? has alloy access panels that's about it.

Proper heatsinks are attached to the driver magnet

Does a car drive well without water?

Does a marathon man run well when he's hot?

I apologize. It is the metal access panels to which I am referring. :huh:

Nowhere near as good as a heatsink attached to the magnet. Standard Lab horn is just a alloy door and the heat will have to 'jump' across to the panel.

K1 you can put your hand on the access panel and feel it getting warm

Would the 1850 horn benefit from having a alloy door for instance?

Quite a lot of space in a 1850 horn chamber. Heat sinks are generally used in tight chambers with little air space, EG Punisher Lab etc

I see. Makes sense. So are the Cerwin Vegas/ B52's just playing it on the 'safe side' with their alloy doors then?

some nice info on this link regarding cooling plugs and attaching them to ali cooling plates.....
