to the OP try this Speaker Repair Latex Adhesive - Professional Grade for Surrounds Cones Dust Caps and more.
as to fabric types for cloth surrounds there are so many types with varying characteristics that that is ultimately up to the end user.
on the cheap if you need to re-seal a cloth surround glycerine can be used.

note: neither of these have any documented benefits for motional feedback experiments

Liquid EPDM Rubber. Some of which is used by the roofing trade. Possibly research what solvent base it is and thin it accordingly. Linen would make a suitable surround. Ideally a die could be made to shape the accordion feature, perhaps with plastic spline cord that could be rolled into the grooves until the rubber set up like when rescreening a window.

Exactly that is what i have had to do with about 80% of the FE103A i pulled from Admirals Tunnel Reflex boxes.

Hi Dave!
Happy New year!

So glad that you've brought this up!
How (in your opinion) does the once much vaunted FE103A stand up in 2018?
Is there an optimal box for this aged beauty?

I've go t a pair in TQWP that I enjoy, and have been wondering whether to go next to a Karlsonator or perhaps a Frugelhorn.

Your thoughts? TIA

Modern drivers keep getting better and there are a lot more of them.

That doe snot detract from the FE103A, especially if you score a $4-10 set of Tunnel Reflexes. But it has pushed their maximum worth down.

Default apologies for the Hi-jack...

Thanks for the reply, Dave, and thanks for your expertise with our Full Range eccentricisies(sp)

Back to my FE103A's...
1) should I move on to something in the 21st century? <grin>

2) what other cabs best suit the FE103A?
mini Karlsonator? Zigmahornet? Frugelhorn?

I'm not unhappy with my TQWP, but I can't help but wonder if there isn't something else to be had.....do you have any thoughts on Bert Doppenbergs variant? (I've collected a few pair of the FE103A)

Thanks Dave for your insights!

All the Best,
Mike

Frugel-Horn Mk3, & Aiko are proven good (Aiko the best we’ve heard). They would probably also do well in Vampyr-V. It is also possible a pair could be used in the miniTower (the casle version is preferred by builders), and maybe a variation of the big Woden BVRs.

Because the T/S can be quite variable due to aging one of the horns (were the box dominates) is the better bet. If you weant to use 2, perhaps the double FH3 (drivers wired in series, one with a big cap shunting it).

Bert’s double ML-V is OK, but was done before good modelers came out.
