Hey roten.
Great job.
I am still enjoying my Ellam 25's.
It is a litte over 4 years since, Troels and i made the design, and it is still a very nice speaker.
i would recomend changing the series coil in the lower bass sektion, with a low Ohm 1,5 mH coil. ~0,1 Ohm
This will lower the range 700-1000 Hz by 1 - 1,5 dB, and at the same time, give you a little moore kick in the lower bas.
Not a bad choice. Not bad at all.
And maybe changing the series resistor in the tweeter filter, with a 2,2 Ohm. It gives a littel more headroom, without being to foreward - in my listening room anyway.
