Blown or what?

[AudioFanatic 10+ year member]

I installed 2 12" alpine type s's for my friend the other day and i had also built the box at 3.0 cuft which is recommended for ported enclosures and when we turned them on one of the subs gave off a sound that sounded like a clapping noise similar to a wood clap when you blow a seal in a box

We have no idea what the problem is and its especially confusing because it only happened to one sub... the weird thing is is that the sound started to go away but the otehr sub started making the clapping noise...

when we called alpine customer care they said that it could be one of three things 1 the box is too big (but the box was built to the recommended volume) 2 We turned them up too loud to begin with (i had the amp down all the way when we turned them on and turned it up only a quarter of the way when the first sub started making the noise) or 3 they were messed up when they were origionally purchased

If anyone has any ideas please let me know

Tinsel slap?

what is a tinsel slap? and how can that be fixed?

if you got the subs wired to the amp wrong it will cause them to make a pop noise, which has happened to me a couple times, check your ohms and wires again and see if that fixes the problem

would the popping noise continue if it were wiring or would it just do it when they r initially turned on... because the noise continues while listening and it seems to only do it on the high notes

Is the box sealed very well?

Tinsel slap is when the tinsel leads hit the soft parts as the sub travels...makes a very annoying and loud slapping noise.

yes the box is sealed extremely well
