First thing you should do is to listen to the speakers in the same room.
How do you know his speaker/system is the better one?

price/performance of ca22rny and D2608 is exceptional!

Is there any measurments/simulations of the speaker?
on and off-axis?

Here is a simulation:

The simulation shows indeed a little dip in the crossover region. After removing the 2.2uF capacitor in the woofer section it looks better:

However this kind of fine tuning is beyond the accuracy of the simulation. But you could try it and find out, if this modification improves the midrange clarity...

i dont think the dip is a negative thing, it is rather a feature
looks like dispersion issues in the 3-8kHz region
tweeter a bit high over 6kHz? attempt to get a nice energy curve?

My own measurings does not show a significant dip around 2kHz and a rather even treble and the tweeter never sounds unbalanced beeing to high in level. I will try my friends cd-player to compare. Thanks for the post Dissi.

Dissi, nice program you have made there. Set the mic axis between woofer and tweeter flanges for this one though, its the way it was made to stand against a listener at seated height.

Its a made, measured, listened and tweaked to preference real speaker we made back then. Not just a sim.

Audio Aero Capitole MKII. It is getting a little old these days but is still a vg cd-player. It is for sure better than my Naim CD5X.
I read a post on this forum that the coil used for the woofer in a 2-way can affect mid range clarity. I used this non-ferrite cored one: JANTZEN-2005 - Jantzen Wire non-ferrite cored coil 2,500mH 0,268Ohm 1,20mm - Europe Audio
Maybe a better coil increase clarity but I can not test this and they are expensive to buy.
I will report if a better cd-player makes a clear difference when I have tried it.
