[Does enclosure size effect subwoofer cooling]

he is talking about normal power and not overpowering.

Pay attention...

If your box is designed properly, and you are not overpowering your subs, your coils will never get too warm, so what would the concern be?

But at lower volume, the sub is seeing less power, so it will not be getting as hot???

a sub cools itslf by moving period!!!! it needs to move lower... volume does give you less current draw and thd that does cause less heat but then the sub is not cooling itself by moving ether so it can get just as hot with low volumes and then again it might not get hot at all depends on the box

subs are box dependent

It is impossible to blow a sub by running it on too little power (whether it be thermally or mechanically). Period!!!!!

Where did he say running it on too low of power may blow the subwoofer?

Thanks for your 2cents on this. If I am running 4k RMS onto a 3" coil it will fail eventually because it can only handle ~2500 RMS thermally. He stated that a sub ran on lower power can get just as hot, so...... By his logic if I am running 200 RMS onto same 3" coils they should also fail thermally, because the sub is not moving so it cannot stay cool.

If I am running 200 watts to each of my 9512s, the 3" coils will not be getting warm, because they have the ability to dissipate the little bit of heat there is. As power increases so does heat, but the coils stay cool because the sub is moving more. The box does affect cooling due to different impedance profiles as well as the tuning of the box itself.

[Digital Designs even need a break in period?!!!]

It can't hurt to break it in. Also, 3" coils cannot handle much more than 2500rms daily, even though mechanically the 9500 can take a lot more power. You will have to give me a ride once you get it all in. I'm Joe's brother, I have a couple dd9512s in my car.
