Best method to hold up stuffing in GM's MLTL with JX92S Jordan's?

Norris Wilson · 7th December 2005, 01:32 AM

Hi everyone,

I have a freind who has built a pair of GM's design of the MLTL Jodan JX92S speaker, that are triangular in shape.
I think they are the version with the higher 45 Hz FS.

I guess my freind did not think he needed to include a physical device to hold up the stuffing during the consrtuction phase.
But now, he is not sure what would be the best method of going about holding up the stuffing.

Could anyone who has built this type of speaker, please give him some suggestions on how to hold up the stuffing so it will stay in place permanently, while preventing it from falling on the driver?

Thanks for any and all suggestions and ideas.

Cheese-cloth bag and a hook to hang it from at the top of the enclosure.

Or a diagonal rod below the bag to keep in in the top of the enclosure, I have seen coat hanger wire inserted into small guide holes used.

There are some pictures of an arrangement on my FE-206E ML TL project page.

Simple is best and don't worry about filling every single bit of space.

Hope that helps,

To hold up stuffing I use those mesh bags you buy oranges in at the supermarket.

I tend to go with the eye-bolts and twine approach, but a length or two of dowel-rod, braced in a + shape across the inside of the enclosure works just as well. Lots of ways, none will damage the sound. Whatever you find easiest really.

Depends on the stuffing - in my triangular 48 MLTLs I've used BAF (bonded acetate fibre), which is like a flexible mat of polyester. Lining the walls around and just below the driver and placing a roll directly behind the magnet, a single rod across the cabinet works ok. (Although I built this as part of the cabinet bracing, it could be added easily enough afterwards.)

If using long fibre wool or similar, the cheese cloth approach sounds best - or grab a spare stocking from the neighbourhood bank robber.
