Hi
See the European morel website:

Check the speakerbuilder designs
Check the Morelline, the woofer is MW166 but the tweeter is the MDT33 but the XO could help you!

Hi!
XO is "cross over".
The MW166 has a nasty peak in the midrange. The Xover used in the Morelline uses a trick: an impedance equaliser (R+C+L // MW166) that when conbined with the coil makes notch filter!
The result a quasi perfect slope (I cannot remember 12 or 18dB/octave) with only a coil in serie with the MW166. You can use lower cost compoments for the "notch filter".
The drawback is that the redge frequency is a bit low so you'll have to make at least a 12dB/oct Xover for the tweeter to maintain power handling and low THD.
Anyway I do hope you have a measurement device unless you'll go into trouble to tune thos complex Xover...
You are Chinese! I often travel to Shenzen & Ningbo....
If I can help you ....
