How do you clean L300 horn inside?

[Domino]

I just ordered one of thise vacuum attachments to clean mine. That's what I love about this forum!!! Great ideas!

[remusr]

I tried to get Giskard's cleaner(s) over to do the job but they said they were tied up! So I did the vacuum thing...pictures attached before & after..vacuum did a great job but now I can see that my horn and driver throats are not aligned. I wonder how significant this 1/16" or so step would be to the sound?
PS - THX for the micro-vac recommendation!

You'll have to get your rat tail file out and ream out the mounting holes to align them. But looks to me that the horns throat isn't round.

I don't think it's a big deal but others may not agree.:dont-know

I don't think it much matters, either.

I am pleased the micro-vac kit worked for you. I've cleaned a buncha LE85's with it....

That explains why they sounded like that...


With care I am sure it is fine... what I do is take the driver apart, remove the diaphragm and first clean the gap and then blow compressed air from the diaphragm side through the phase plug... it removes all of the debris on either side of the screen.

Yup, that's the best approach.

Yeah... well... life isn't for everyone and I'd pretty much put people who care about red wax seals in that category... It's probably best if a roadside bomb puts their concerns into perspective...

Hope this helps

Hey If it was good enough for JBL ,Well then it should be good enough for us?

Red wax is easy to find..., sounds like a perfect opportunity for someone to produce a little "stamp" to press into the wax...

Oh the scandal! Selling JBL drivers as having intact red wax seals on ebay> , but, WHEN DO YOU WANNA START?











Just kidding!

57BELAIRE- the woofers are 136A's; 1 has apaprently been reconed with a 2231 cone per writing on rear, and 1 refoamed improperly as it now has surround front and back. They seem to sound ok.
ZILCH - thx for the vacuum recommend'n.
