How much power can a 3 inch VC take?

Application has nothing to do with how much power a coil can handle thermally.

I was asking if he a specific goal in mind.

from "my experience" clamped 2.5k RMS is the limit on a good vented motor with a big 8layer flat wound ccaw. rms meaning the sub can handle this all nite and day.

now i have ran over 5k to a 3" coil plenty of time and it will take it but you have to know when to back off, thus not rms and its being over driven.

just because you have a amp that says 5-7k dosent mean ur ever going to get it with impedence rise with box and music. alot of amps that claim 5-7k clamp on a burp never put out actual power or come close even with a bank of batteries to support it...

you need to look at coil mass and surface area - those are pretty universal as far as directly related to power handling. The thermal transferring to air or surrounding materials is extremely complex and requires complex FEA to even begin to understand. Most just make stuff up and it semi-works. JBL has done good research on motor venting and hold patents on it.

A 3" Vc with a 3" winding with has more surface are than 4" vc with a 2" winding width - so the length of the coil matters a lot here too as well as the mass of the coil. There is no easy answer.

VC diameter by itself means only that the VC has that diameter. It doesn't speak to anything that has much to do with power handling.

wrong
There are many different types of coils. An eight layer aluminum flatwind coil can handle up to around 3000, not much more.

And how does the fact that there are many types of coils make what I said wrong? That is essentially what I said. That it is 3" means only that. It doesn't say anything about coil height, venting, winding material, pole material or anything else that actually determines power handling.

In my application I can run 3500rms ea sub with no issues. DC 3in stealth coils. I've burped em at over 14k to the pr.
