Sorry...can someone explain what is the MAD tech by Ambient?

The.mad do not use a filter but a specific chamber like the new campfire

Multi Armature Driver

Since they make iem with more than 20driver

Hey Dhruvmeena96, I drew out the sonion 38, 33, 2389, and est build per your instructions...I hope it is correct. I realized all the tubes are 12 MM and are 2 MM in diameter..I foresee a collision in the canal with all those drivers and tubes! If I needed to stagger them or merge tubes, would you merge the 38 and 33 into the same tube? What about a 1 MM extra long tube on the 38 so I can back it out of the way? Appreciate the thoughts...

On my 38d1x the tube of 1mm gives better result, at home I have almost 6 cm long in 3D chamber, I could do longer but I have more space

1mm ID tube works as a low pass filter.
Small diameter tubes reduce high frequency output.

1.5 - 1.6 mm ID tube works for mid - high frequency or full range drivers
Avoid diameters below 1.5mm

1.6 mm ID tube works perfectly for high frequency.
Conical shapes 1.5 ID on bottom and 1.7 - 2 mm on top for Better high frequency.
Avoid diameters below 1.5 mm

Conical shapes may reinforce higher frequencies.

Tube resonance fills response at upper frequencies
10 mm to 20 mm is suggested
Optimum usually at 10mm .

I feel like you’re teaching us things we already know lol

On the MAD tweeter of Ambient Acoustic it’s like that, it’s called 'horn'' it’s the principle of the horn of on the compression tweeter

Go with smaller ID on woofer, it helps.
33AJ can go with 1.5
Uppermid and tweet has to be 2mm spec because tube resonances begin there

Hahahahahha lol
Been there done that
The Horn
What's so special to make a name out of it.

The focus now should be that how to get EST driver from ~90dB to 110dB with a horn. Well, get the horn to boost a heck lot.(20dB is possible with a horn in a closed space with recieving source very near by but the horn will be pain in the ass... Only Exponential and straight conical can be done in iem as tractrix takes the space

Otherwise it's not worth it
Isn't it @Aldo40

That does look just like the Campfire stuff actually.

I approve I do it right in the nozzle with the EST, we don’t have much choice but it already opens the high frequency, I manage to make a Horn 5mm long ID in 1.5mm/ ID out 2.3mm

Yes it is exactly that I had seen one. I exploded both. I tested and measured MAD 10 and 16 by plugging each bores to measure the independent driver and indeed none was filtered. Amazing then it works well but it is not to my taste, I prefer ve8 for example or Erlkonig
