It looks like you have a standard swedish home, i suppose the rt60 is quite high?
You should turn your attention to the room or at least add foam absorbers between the speakers for the early reflection of the backwall? it should definetly give you more midrange clarity and less harsh sound as the volume goes up if you do. 7-10cm deep. ~1-2m high
or build a speaker with more radiating surface in the midrange and a waveguide to lower distortion and get a higher directivity, 2,5, d'appolito etc? if you want more clarity in midrange?
instead of buying a new cd-player or change a coil.?

I moved the speakers to a better place in room and also made some damping of reverb. I am not buying anything, just testing.

Dissi, did you find time to produce the curves with the mic positioned as I mentioned for the simulator axis? Thanks.

P.S. How does it simulate cabinet diffraction and radiators angle responses just from IEC baffle published data? What mathematical technique? Like in SoundEasy?

Moving the mic 6 cm below the tweeter axis does not change very much, sorry Salas, it's just a simulation.

The spl is calculated by summing up several hundreds of small sound sources located on the diaphragm and along the baffle edges in a 3D coordinate system. Individual driver response is retrieved from manufacturer datasheets and other sources. Modeled driver response in a specific baffle is adjusted with a parametric equalizer to match the reference.

Maybe it does change the off axis speculation a bit though?

I could cut that capacitor out of the crossover, I think I can reach it inside. But to solder it back again is harder .

That capacitor we put it because we felt the mids bit forward in the original voicing. It was without it for some little time. Still it was in another room, in another system, in a different materials cabinet, so you may judge for yourself further.

Yes it all depends, hard say how it would sound in my room. I will not do anything until I have tested a few things. Maybe someone knows how a little recessed 2-2.5kHz affect mid range clarity? I know that if you do not have those over tones at all of speach it is harder to detect what is beeing said, I did a test of that once many years ago. That is why telephones has a frequencey range up to about 3kHz.

See Harbeth domestic VS studio monitor line about that. It depends a lot on the surroundings.
