ESS Heil Diaphragms
I see that there are replacement ESS Heil Tweeter Diaphragms available at Parts Express for $80. ? ESS Labs ? Air-Motion Transformer, Heil, Replacement Driver, Ribbon Tweeter, Replacement Diaphragms, AMT

I don't know anything about ribbons and I'm wondering what other parts are needed to complete a tweeter? Would those work as they are right now? Do they require a special amplifier?

Hi boris81 - sad to say you need the other part that cost $350. ESS Heil Air Motion Transformer AMT Tweeter

The good news is that they already come with the diaphragm included. Sooooooooooo if you spend $700 bucks you will save $160. Try that logic of how much you are saving on SWMBO - mine does that to me all the time and I figure payback is a good thing. :joker:

BTW - should you actually be foolish enough to try that line on SWMBO I completely disavow any knowledge of the idea and I don't know you - I don't know nuthing - and I didn't do it!!!! :rofl::rofl::rofl:

ah OK.. it sounded too good to be true.
I was hoping the rest might not be hard to DIY.

Well - some strong magnets and a frame to hold things together and you might have something. I always thought about doing something like that but seeing as I already have a pair of AMT1's that I use I keep coming up with other projects - of which there is a backlog to catch up on already......:rolleyes:

Yeah, you need a considerable and focused magnet structure.

Its easy enough to do, my own attempts can be found here:


Obviously I cheaped out on the magnets but hey, any stronger and I'd be wiping my bank cards, these babies really arent shielded!

The diaphragm is the hard item to make IMHO.
You can drown the guy in magnetic flux by using a bunch of neodymium magnets and a wood frame to hold them and the diaphragm.
If you have metal working equipment, you can get perforated steel square or round perforations, and roll a bead around the edge so when you bolted them together with the diaphragm in the middle it will stand off a wee bit from the pleats. Then you can glue magnets onto it leaving some holes open - else no sound will get through.
I would do that except I have too many projects, and the heils i got work fine. If anything the tweeter needs to be muzzled a bit. Dropping the diaphragm in 5X the magnetic flux could make you deaf ...
