Fostex 127E phase plug install

[widman]

The dust caps on the 126s and 127s must be very inviting. I didn't even have 5 hours on my speakers before my son's friend popped one in.

I poked a hole in the tip with a pin and pulled it back out with a piece of wire. Then I sealed the hole with glue. Now I really need to do the puzzlecoat mod and hid the discoloration.

Kids just love to poke at speakers for some unknown reason. I've seen this happen to all kinds of drivers; even dome tweeters, which don't take kindly to such abuse. Some kind of protective covering is a must with small children around, or puppies.

I was actually thinking about a protective covering on the kid. Then I don't need to worry about the effect of a grille over my speakers.

Originally posted by kazoo I bet that if you told him you need one for this speaker or a custom one he would create one for you. I hope I am not stepping on Daves toes with that comment.

The new FE108eS plugs are actually the same as the prototypes for the FE127. The plug needs to be a bit longer than the stock 103/1197 plug.

I'm excited that you found success. I may try this again. I'm pretty gun-shy after loosing 4 out of 4, but -- even with the scraping from the black goop at high levels -- the plugs make an improvement. It was clearing up that last scrapping problem that lead to the death of our 127s. I'm glad their death has produced some positive results.

That would only have been because the mail didn't get thru. It is a crime that SPAM & the resultant antiSPAM have made email an unreliable communication medium sometimes.

I have modded FE127 in stock & ready to ship. 126s might take a bit longer, i'm working thru the next batch.

I can vouch for the 126s. Elsewhere I described them as being a bit like a baby version of those modified Decware 206s. They're almost as good as the Sigmas, and probably have an edge in the bass. With plugs in them... I'll have to think about it.

It's true with every speaker... Mine have also suffered sometimes.

But I think it's an educational problem. My daughters did touch them only once. After explaining 'em firmly why they shouldn't, they never did it again.

The general problem is with my friend child or my daughters friends...

I found one solution : the tweeters are soft domes and I have phase plugs in the boomers It only let some fingerprints on them when they touch it...

I poked a hole in the tip with a pin and pulled it back out with a piece of wire. Then I sealed the hole with glue. Now I really need to do the puzzlecoat mod and hid the discoloration.

Did you try a vaccum cleaner? It works very well on mine old speakers. You gently approach the bare tube closer and closer without touching the speaker until the cap comes back.

There are quite a few threads about popping out a crushed dust cap and I tried some of the suggestions. The dust cap on the FE126 is fairly stiff and wouldn't pull back out with either a vacuum or tape.

I agree on the education point. Both my kids understand that speakers are for listening, not touching.

Hi gychang,
At the time I did the dust cap removal, I had only about 150 hours of playing time on them. To my ears the phase plug smoothed out the higher frequencies. It made the speaker easier to listen to. They are in the BIBs right now and sounding pretty good.
