I always liked the and seeing the large ScanSpeak D3806/8200 dome getting out of stock here and there, John/US came in handy with a pair of Accuton C 2 44-8 inverted domes and a pair of HIQUPHON OWI tweeters as well, thus the SP44 project was on track. Circuit Design Suite 12.0.1. We could also call it Ekta-Accu, but SP44 it will be.
Comparing SP44 to the Ekta is obvious and despite not having them side by side, I'm afraid the SP44 will beat the Ekta from a less coloured upper mid/lower treble. These ceramic domes are something special. Now, what can the C44 do the D3806 can't? Well, it goes deeper and it goes higher and it has a remarkable flat response all up to 20 kHz where a serious cone break-up occurs.
20 kHz is really high and nothing to worry about in a 3-way system. The C44 is not particularly sensitive, around 85-86 dB/2.8 volts - but all the same a good match to the 18W/8531 driver that usually can be tuned to a system sensitivity of 86 dB/2.8 volts. Looking at C44 horizontal dispersion, 6 kHz seems like a good starting point for crossing over to the tweeter, thus the C44 is really able to handle all of the important treble range, because we can go even lower compared to the D3806. From simulation 900 Hz looks ideal, but no guarantee this will also sonically make the best transition to the 18W midbass. Has to be tried. Last but not least, the C44 has the most clean cumulative spectral decay I can remember, i.e.
