AKG K240 Sextett questions
Dec 7, 2007 at 2:34 AM Post #46 of 57
OK...I just received my Sextetts I won off Ebay a couple weeks ago (shipping from Canada). They seem to be in really good shape...the pads are in great shape. The only thing I can see that I need to replace are the elastics as they are pretty shot. I've been reading the various Sextett threads and can't find any step by step instructions for replacing the elastics. Does anyone know if there is such a guide? I do have the K240 service manual so I have a pretty good idea how to do it...

Oh...and they sound fantastic! Based on the all white radiators, it appears to be one of the late models.

There's no trick to it that i know of. Well, aside from doing it with the earpad of the side you're working on flat on a table or desk (with the rest of the headphone hanging over the side). And it makes sense to do the strap end before the cup end.

I don't know, I've had some K340 pads around that seemed to be much nicer pleather than the new pair of K240 pads I had at the same time. I couldn't be dead sure it wasn't an aging issue, though.

Which brings up the point that you can't remove nearly as much of it as you could potentially with a k340. It's easy to see where the sextett grille connects - the most you could do is a small circle over the driver itself.

I don't think it would make much of a difference, if any.


Since I'm working on a slightly "custom" project for someone, I was given the go-ahead to forcibly remove the grilles on a pair of sextetts. I can now confirm that some are indeed glued in place, and there is no non-destructive way to remove them if they are glued.

So to anyone whose grilles don't pop off easily: don't try to force it, they aren't coming off intact.

I knew it. So glad I didn't just try to force them. So sad that I now have to figure a way to finish cleaning the foam and gunk off my grilles without being able to take them off, though.

Well then, thats that.

I wonder though, there is a trick for removing epoxy without using damaging chemicals. What if you were to drop some liquid nitrogen over the areas that are glued? Would it make glue harden and become brittle and break, without damaging the plastic? Although the liquid nitrogen may also crack the plastic and god forbid it got on the driver or radiators. Perhaps dry ice would be safer?

I hate to necro this thread but the one I made has yet to be "looked at"
I need to know how old/rare the K240's that I got out of a bin at Goodwill

I would love to know how much they went for at the time of release (if possible) and maybe some quick specs on them. I really don't know anything about headphones nor speakers.
