Sub getting hot

[BDIDDY 10+ year member]

I have the B12 in about a 4 cuft. box ported. Only have about 800 watts running to it and I dont let it distort. It gets hot well its almost always hot after I push it pretty good. Just wondering if that was bad, or something I should watch out for.

Thanks

If you push it hard, of course it will get hot. Electrical energy dissipates as heat.....

So its not a bad thing? Just as long as I dont let it distort right?

How do you know it gets hot? Do you take it out and feel it? OR is it inverted?

The cone gets hot.

If it's getting warm (like you can still touch it and not say "ouch") then it's probably not anything to worry about. If it gets hot enough to burn your skin or to start smelling it burning, then you've got a problem. When I had my 'bahn inverted in my truck, I could sometimes feel heat radiating off it after being played for a while, but it never hurt it to get a little hot.

well as long as the voice coils arent getting really hot then u should be fine. U dont wana be melting those voice coils...

Yeah one day I smelt them and turned it down right after. I think I was just doing, I guess you could say the final burn in. It doesnt burn anymore though.

Thanks for the help.

just a note....did you remove the plastic cap from the magnet?

When I first got the sub the cap was there, I removed it, when I got it reconed it didnt have one. So yes it is removed.

Thanks for the help.

As long as you don't smell actually coil burning warmth on the cone is normal. ONce you smell one blown sub you'll know the smell forever.

My B-15's dust cap gets hella hot. Glad this was brought up, I was starting to worry. I talked to the guy that I got it from and he said that I might possibly be over powering it.

It's kinda odd, when I have my A7 at 2ohm (~700w) with my 3 HE2's, it could pound all day until your eyeballs rettled out of you skull. Now with the A7 at 1ohm (~1400w) to the B-15 I can't get half that loud with out smelling the vc or it getting scarry hot. I have been taking it easy with it until I get a time to make another box. Right now it is in a 5.5cu' box ported to 24Hz and I think I'm going to put it in a 4cu' box ported to about 30Hz.

Just out of curiosity what is your subsonic filter set at?

The XBL2 is in reality tiny, isn't it? So I would assume heat buildup is quite normal for a sub like the brahma and XXX. RF VC's aren't XBL2, I would imagine them to be large, so they might have better cooling abilities.

but the xxx takes 1600w rms thermally for daily...i am not sure why trixters would get so hot
