I'm starting this thread to share information about crossover networks for In Ear Monitors (IEM) with balanced armature speakers (BA). Please share your thoughts and experience.
In this thread I will be talking about my experience while I do a trail and error process, making custom in ear monitors (CIEM) in a three way setup with a passive crossover. I'm ordering my stuff online from Mouser.com and I'm still looking for an analyzing tool like a 711 coupler to simulate the ear canal and test frequency respons from my setup cause I think that is a very important step in the trail and error stage. I will also share all the documentation on the products and processes that I use.
What's the goal for me? Find the best speaker with the best frequency response for the chosen bandwidth or frequency and fitting crossover to create a reference speaker sound in a three way system.
Inductors : Still reading on best quality brands
Capacitors: Still reading on best quality brands, these are the most expencive and difficult things of the crossover network.
Resistors: Same as for the inductors, still looking and reading
All of the above available at www.mouser.com
You can a cable from Westone and make the female connector:
I prefer the Amphenol coaxial MMCX connector. You might know them from the Shure IEM. They are available at Mouser too.
You'll need a decent soldering station with tempature control. BA speakers are very sensitive for tempature and if it's a bit too hot, they brake.
If you really wanna go the whole nine yards it would be best to have an artificial ear simulator.
You can find one here http://www.bksv.com/Products/transducers/ear-simulators/ear-mouth-simulators/4157?tab=accessories
There is a lot of software out there to use with this tool. I will post more about that later.
You'll need to put all this in a shell but I don't want to focus on that as there are other threads that cover that. So please, let's talk about sound, speakers and crossovers.
I have some documents I will share in my next post.
Hope you join in and share.
