Pretty expensive drivers you have there. What are you hoping
for to get out of them? How do you intend to use them and
where exactly ? If it's no secret, how much did you pay for
these?

This combination could make a very good sounding compact two ways if done properly.
Both these are new and the E650 with receipt issued dated May of this year.
I paid slightly over a thousand Euro for both.

How exactly are you familiar with speaker building ?
Tools, skills, experience...?
Do you own a measurement system ?

I got the skill of wood working and have most of the wood working tools.
Actually I am more experience on playing around with the electronic components and tubes.

The E650 sounded very good and preserved and revealed the very texture of piano pieces.
Paino sounded fantastically real through the E650 and much better than my ATC SCM20SL.

You are trying to clone something, right ?

Since you haven't answered my question about
owning a measurement system I will just ask,
are you willing to get one ?

I think it would be a shame not doing it properly,
without measuring. You bought super pricey drivers,
it would be only logical to get any kind od functioning
measurement setup so you know what you're doing.

What you ask here is similar to ordering a custom
made tuxedo over phone just saying you are male and
medium height .

There is no such existing speakers using the same drivers that could be cloned.
I only got simple dB meter to mesure the sound level,that`s all.
I might end-up driving the speaker active.

And I thought you were trying to clone SF Extremas .
You did ask a year ago if somebody would tell you the
cap value for tweeter XO.

For certain is you are now closer to clone them than
a year ago with a different bass-mid driver.

Dynaudio C1 uses technology close to your Esotars.

What am I trying to tell you?

Don't be a cloner. Learn about it and do it properly.
It's easy.

Whatever route you take, active or passive, you need
equipment to check your work!

A decent sound card, pretty much bunch of free software
to use, mic, all in all should be no problem.

Personally, I deal only with passive filters. Gathered
parts and magnet wire for 3 decades of diying.

XO project you're looking for can be fixed in no time
and be state of the art.

If you have the guts for it, I'll guide you online.

Cloning Extrema is a huge project.
Actually I got every things needed for this.
I haven`t got the `gut` to push the on button.
