sealed XXX18 slaps

[Tyan 1]

so i throw the XXX 18 ina 4.5cubes sealed box ...it sounds good and great but i have this slapin noise from the sub when i turn it up

.....so it must be the tinsel leads

is there any way to fix this or did i just soldered them to high ....

Is your box leaking air anywhere

nope ..the box is made well ...as u can also see

The leads do look a bit long, and even with pads you can still hear the slap at times.

i know that ....a buddy here has a XXX 15 .....yp u can hear the leads slap ...but not so much and he has 3kW + on the sub ...

i will look into it today and try to set the leads lower and its goin to go in a ported box ...

or i will just have to change the tinsels with softer ones

Is your friends ported enclosure the exact same size and tuning frequency?

The simple answer for the difference would be that his enclosure, with it's enclosure volume and tuning frequency, is controlling excursion at given frequencies in such a manor that the driver doesn't excurt enough to cause lead slap.

If it is supposed to be the exact same size and tuning frequency as yours, then there is something different with your enclosure that is allowing the driver to have more excursion which is causing the slap.

EDIT: Missed that your enclosure was sealed. In which case, your friends ported enclosure is limiting excursion around the tuning frequency whereas your sealed enclosure is not (excursion is necessary for output in a sealed enclosure). That is likely the reason why there was no lead slap in your friend's enclosure.....it doesn't have as much excursion at the frequencies where the slap is occurring.

That looks like some sort of laminate over particle board wood.... If so, cut it up and burn it and rebuild with MDF.

[Tyan 1]

yp it is a particle board 25mm (over 1") ...and a lot of screws and glue ....

and in the sealed box there was not so much excursion (it was kinda small for a XXX) as in the ported one ....

but there is one more thing ...in the ported box the sub is up ...in the sealed there is sideways ....

a buddys XXX 15 is sideways and there is also slap shit ..but not so noticeable

That's not a well made box then. Get rid of that particle board crap and use some mdf.

No offence, but to me it looks like shit.

We all gotta start somewhere.. I second about rebuilding the box though.

when u soldered the leads did u jsut solder as long as they were?
