Hello,
I just finished a set of mini speakers based on the TangBand W4-1337SD
The official FR curve is really attractive but is missing a raised up band from 1KHz to 9Khz that I measured in a closed test box:

Taming this curve passively means quite a few components: one RC impedance correction, a notch filter and a 12db low pass...
That makes me feel the need to experiment on active crossover and equalization (minidsp?)
After many attemps here is what I got in the final speaker:

I am quite happy with the result, especially the sound stage. Of course real bass is missing but with a sub, it's OK.
This first attempt with a full range driver make me think that a good solution might be a 2 way speaker: full range + (sub)woofer
About the aesthetics, I made it with a very high WAF as you can see:
