Sealed enclosure requires more or less power?

Question

Do I require more power in a sealed enclosure or should I go less? And how much more or less? Lets say I'm running a 500 watt subwoofer sealed, what power should I give it?

Answer 1

You should match, or nearly match, the power rating of the subwoofer regardless of the type of enclosure it's in. The main difference is that a subwoofer in a ported box can be damaged by playing low-frequency notes below the tuned frequency of the box; therefore if you're picking an amp for a sub in a ported box, you should find one with a subsonic or infrasonic filter to cut out the lowest notes.

Answer 2

You should go with a 500+ watt amp and watch the sub closely - don't let it go past its excursion, especially at low notes.

With a ported box, you can usually feed a subwoofer quite a bit more power near the tuning frequency for short periods of time.

Answer 3

i dont believe a box has antyhing to do with the power of the sub. however u want to run the sub at the around the rms *example* 500 watt rms sub, 1000 peak. run that sub at about 600-700 watts. u always want to give ur sub atleast the rms, but dont exceed the peak.

Answer 4

I have two 400 W subs in a sealed box, and im running 400W to them both... if I want it to have more thump, I turn the base up on my head unit.. persinally I wouldnt run more power to it then what its rated for.. it may take more power, but I wouldnt hook it up to more power.. but thats just me..
