i was given 2 Manger drivers By Henjo (Thanks for all the cool stuff), one was known to be broken , but i thought maybe i can repair it. unfortunately more was broken then i thought and i could not 🙁
Because i guess the price, i never seen the inside of such driver so i thought maybe you would enjoy seeing it to ? let get this thing appart 🙂
i will make a simple ugly test box tomorrow see what the remaining working one does!
Kind regards Joppe

hello wrine
Can you estimate the cone weight and thickness? how thick is the wire on the coil?
manger uses 4 different materials for damping in the housing. Bottom and lid are 4 cm thick. in the middle a strut. greetings

A very cool and unique wideband driver. I,ll take these over those full range drivers
with terrible waterfall plots any day

Manger weighs 25 grams.
Apogee is not A Manger and Manger is not A apogee ,two different speakers 😀😀😀.

no one said they where to compared to an apogee ? as far as i know 🙂 far from it. in the way it works at least. you can compare frequency response of a planar magnetic and distortion though.
ill weight the membrane + vc 26.6 Grams 🙂 a double coiled rather heavy foil for a planar i made 2.5 times the size was around 20 grams 🙂

yep esl always wins 🙂 in the weight game..
anyhow Manger came with a price 500 +- apparently they could have replaced the coil from the backside.... WHOOPSY now because the 2e on is also broken i asume combined will be 800-850 euro or maybe slioghtly less. since it does not need a new membrane
well at least we finally seen the inside 🙂
i wont be spending that much i am afraid.

Can you figure out from your dismantling experiment on how this would be performed? Any hints? Any ideas?apparently they could have replaced the coil from the backside
THey said the remove the magnet structure. how i have no clue 🙁 maybe because of the press fit ? play with some heat and or cooling ?
The neodymium magnets not tolerate the heat (strength loss). Occasionally, the coating leave the magnet.
The mass comparison is nonsense. The rise time of the manger is extremely fast. Distortion measurements only lead to arguments because they are high in the midrange. Listening to a test with just one speaker, who can make a judgement? greetings
they just told me the second one might need a new membrane to, since they are 30 years old. so repair would be +- 1000 give or take.
in any case i do not have money for that. so i need to think about something to do with them. not gone destroy them any further, but sitting on a shelve is not good either. maybe wait for funds.. or make someone else happy thats willing to take the plunge.

Yeah i have no clue how they do itThe neodymium magnets not tolerate the heat (strength loss). Occasionally, the coating leave the magnet
I am prettu sure i wont be able , to precise.Joppe, you are able rewind the coils, I've seen your projects. Thanks for the videos!
True, i mean it works on a complete different principle. calvin explained it a little better in my videoThe mass comparison is nonsense. The rise time of the manger is extremely fast.

He explained it much better !! i must add. i was half way there 🙂 but could not get it completely. thanks !True, i mean it works on a complete different principle. calvin explained it a little better in my video
This is a good point, a quite complex matter and it happens between 80°C and 230°C. At what temperature the demagnetizations occurs depends on the temp. class of the magnet, but also on the shape of the magnet. Most neodym magnets might be in the 80°C or 100°C class. Ferrite magnets also loose their magnetization, but this occurs at much higher temperatures around 250°C.The neodymium magnets not tolerate the heat (strength loss)

In this video can see at 3:50 the pressing of magnet structure into the alu basket. At 0.25 playing speed can see well a viscous black fluid, filling the gap between two metal surfaces. If it's urethan or epoxy resin, very difficult (or impossible) to disassembly.THey said the remove the magnet structure. how i have no clue 🙁 maybe because of the press fit ? play with some heat and or cooling ?
