Not sure if this is a problem but...

I just built my new box 6.8cft @ 27.8hz with around 14-15inches of port. Sounds GREAT on lows but if I put my ear upto the sub I can hear a slight bump on highs from the cone is this normal due to such low tuning? I have my HPF @ 80z and my LPF @ 25hz. I try not to play highs my amplifier is "tuned" to 38v which is 1500rms and I see minimal voltage drop. So my only guess is its just a slight pop from highs and playing above freq? IT ONLY does it on really highs u can hear it like a tap or a pop its not even audible unless u put ur ear upto the sub on full tilt, if I turn the gain just down a bit (widge of a finger nail) it stops a bit but slightly adubile.

I just hope im not blowing my subwoofer, I cant really explain the noise and my cam didnt pick it up so has anyone had this happen? Its not a pop noise it doesnt sound bad mechanically it just sounds bad audibibly it sounds like airs hitting the cap and making like a pop or a tap sound haha.

IT NEVER did this in my old box tuned @ 38hz never is this unloading? I didnt put any 45's in and the port could have been mae better but I dont hear it from the port I hear it from the woofer. its NEVER done this on any of my boxes I tuned high.

maybe something's loose in the box or woofer, or maybe you could try some polyfill.... idk other than that. you've got me stumped

[Sammitch0]

Nah I just built the box its not that. Its not woofer because its only happening because of the box never did it before i think im buying into it toom ucha nd its just normal noise i just want to make sure. I know if Played below tuning before the box would bottom out so im assuming playing too high ABOVE tuning can maybe cause this noise im getting I hope. I did hav e alot of saw dust in my box after I made it so some coulda got in my subwoofer but ive never heard of that happening. and by a lot I mean a lot I tried to clean it all out but I couldnt reach it all (BOX IS HUGE) so it accumulated in the corner of my port so I sucked it out I dont think thats causing it thought because if there was sawdust in my coil it wouldnt be good.

Is it coming from the woofed or port area

He said woofer but I'm confused about his crossover settings.

I hope he means LPF at 8 0 and HPF at 25.

You shouldn't need to worry about higher frequencies causing damage of any kind.

I don't know if you can be helped over the internet, almost need to hear it in person.

What kind of sub is it? Could be a lead just a tinny bit longer then the other.

[Sammitch0]

The woofer and I just read sawdust can fuck ur VC up but I tested it and its fine theres not even any sawdust near hte pole I think that aspect is fine... Ugh what to do :-/

First off, HPF shouldn't matter and your LPF should be set around 70-90hertz. If your confusing LPF with subsonic, set it to 5 hertz below tuning frequency. Check your spiders, see if they're ripped. Check your cone and see if its breaking away from he former. Basically, remove you sub and free air it on low power. Find the source of the noise, obviously there's a problem.

I meant subsonic LPF is 70 lol sorryu and ok ill tak eit out and freeair the bish, I honestly am not too worried about it broski

[Sammitch0]

Went out listened again I cant even hear it now was probably just that song and the highs I turned my LPF to 60 and my subsonic a little more up turned my gain down a smidge and it seems fine, probably just light clipping and playing way too high over tuning.
