Coil Differences

[AUDIOADDICT02]

No what I'm sayin is most 3in coils will take more power than smaller coils.

I get it now......thanks!

So what's the difference between vc sizes?

Usually with a 3" coil you get a bit more thermal power handling because the windings are spread over a larger surface area (assuming the same winding height)

There are tradeoffs though. A 3" coil has a larger former obviously and is usually heavier than a smaller coil. This gives the sub a higher moving mass and lower Fs.

A smaller coil will probably be more efficient due to weighing less, although to get the same power handling they will use a thicker gauge wire for the winding which lowers efficiency (less windings in the gap)

It's swings and roundabouts. Bigger doesn't necassarily mean better. The Atomic AP12 runs a 2.5" coil and I've fed one of them the thick end of 4kw.

Also, Assuming the sundown 4 spoke basket has the same spider diameter you have to consider the different spiders. A 2.5" coil will have more spider than a 3" coil on the same basket.
