coating FE127E

[aussiebuddha]

I have a pair of FE127E in their recommended enclosure, and unfortunately one of them has developed some mildew spots.
It's not too bad, and certainly doesnt affect the sound.
I managed to remove some mildew, but still some spots left.

Is it possible to coat the cones with something to protect them from this happening again and to cove the damage?

I've read in other thread about using something called modpodge for coating the speakers, but i'm unsure how would this affect the sonic qualities without doing any other mod, and whether this would cover the little spots.

Thanks in advance.

I'm surprised Dave (planet10) hasn't piped in on this yet - I'd suggest you PM him, he's rather familiar with this driver

EnABL How-To for Fostex FE127e and other speakers

Might as well start out and head towards the whole deal.

I'd get some anti mildew stuff from the shops, the kind you use in showers, and just wipe the whole cone down trying not to get it too wet.

I am an amature mycologist, molds are the bane of my life when growing.

I'm thinking of doing the following in steps (due to $ and time available being little currently)

my impression from reading various thread is the speaker should be functional after every step with slightly improved performance.

1) remove dustcap and coat with modpodge

2) install phase plugs

3) EnABL

focusing on my immediate need (step 1)

will standard modpodge cover the spots or is it completely translucent?, and if translucent, what can I do to cover the spots/paint?
is it safe the run the speaker dustcapless?

[planet10]

I only recomend phase plugs if you are recovering the driver from a dustcap accident.



Undoped modpodge dries clear. It needs some thinning, and instead of water one can use food colour and create a coloured cone. You would need to do this to cover up mildew spots. Probably one that is similar of darker than the spots.

Some examples of coloured drivers here: It's not easy being green (apologies to Kermit)

Before modpodge the trifoil helps tame the 7k peak.



This is at what i call the pre-treat stage, before EnABL.

Note that EnABL2 gives some improvement over the original. Here is my version:



Bud has posted some additional rings (althou i believe his added to a set with EnABL (1)) that take it a bit further.

Before spotting the FE127 practise on something you don't mind if you don't do such a good job.

thanks planet10
a few more questions if you dont mind.

1) could I use black printer ink for this?

2) how many coats do I need?

3) where can I can more info about the trifoil?

[planet10]

Liquid printer's ink will work (at least the one's i've tried) but the black ones are really dark blue.

Trifoil: The thread i 1st pointed to should have everything in it

Thanks planet10
Will try these mods..

I guess the trifoil is just painted on with damar.
Does it need to be precise? are there any templates for this?

Regarding the modpodge, is it possible to use PVA instead?

Sorry to ask so many questions, I guess most of this info is buriend in those threads, but there is so much info in there it's quite difficult to find, and believe me I've had a good look for a few hours until my brain started hurting

The radii are important. My patterns are wide enuff that i cover them. I have templates (made of cones from dead drivers) for doing dozens at a time. For a single set marking off the extents of the pattern with a 2H pencil or somesuch makes sense.

Regarding the modpodge, is it possible to use PVA instead?

ModPodge is a PVA formulation. It has flexibility (when dry) properties that suit the task. Thinned white glue can be used, but we do know that modpodge is available in Oz.

And do read the entire thread i 1st posted. There are some quite important pointers, warnings, and tips.
