Help! lost an FE127E today...ugh...

[cjkpkg]

Well, I need some recommendations for drivers in the Fonkens...Something dimensionally as close as possible.

EL70 wont cover the hole good enough and is much deeper
what about the FF125K?
The CSSFR125SR?
CHR70?
Alpair7?

any Tang Bands close enough in size?

Also, I have been using the PASS F5 in this listening room as of late...either that or my SimpleSE.

Dimensionally as close as possible would be the FE126E (identical frame).

How did you lose the driver? I have a pair of 127's sitting in the closet, if you're desperate.

By the way, the CHR70 was a close fit (I put them in some FE127 cabs) but I don't know how it would do with the cab in question.

You don't have FX120 on your list. They even have the same mounting hole pattern as FE127.

FE126 and FF125K will fit. But neither work well at all.

The port tuning of the EL70 primeSize miniOnken can be retrofitted into a set of FonkenPrime. If you can figure out how to make the EL70 fit (like a bit more baffle) or a graft job you won't compromise the performance.

If you can get a set of FE127 jump on them. Don't toss the dead drivers... the cones can be used to make a trifoil template.

Yes, FX120 could work. I could check the tuning.

Actually, your boxes have slightly "better" tuning than mine IMHO, as I never anticipated using the FX120 in mine. The vent length in mine is a little too short.

Whilst everyone has posted answers to the question of what driver will fit, im amazed no-one has dared to ask the 'How?' question. so in a light-hearted way:

To the OP:

I would love to know HOW you managed to lose a driver...Ive only little personal experience with Fostex, but i was surprised to read that you lost a driver.

I would expect that your ears would have to be bleeding profusely, for them to be loud enough for the coil to go o/c

Also while replacing the drivers maybe its a good idea to check the amplifier out too. Im aware its a reputed design, but an amp problem or higher than desireable DC in the output would explain alot, should it be present.

UNLESS you just had the fostex VERY loud...

actually, we've found at least a couple of ways to destroy an FE127s voice coil (or two at once in a bipole enclosure)

hint: a lot harder with a tube amp than with the shorted DC rail of a Nelson Pass mini-aleph (what's that amber glow from behind the dust cap?) , or perhaps the hot switched output of a DC coupled chip-amp


yes, the FX120 will work very well indeed in the Prime Fonken enclosure (I've enjoyed Jeff's on several occasions) , providing of course that you can fit the driver in the baffle and that magnet or other internal bracing does not interfere

I was swapping preamps - without powering the amp down - and a terrible noise came out of the speakers - thats all she wrote.

My own stupid fault for not powering down. Ugh...
