Dear all,
Is there anyone here who have done some CLIO (or similar) measurements of the 045Ti on either the K2-S9800, K2-S9900 or the Array 1400 horns?
The K2/Array crossover points are very different, in the 9900 they are crossed at 15k and in the 9800 it is lower. In the Array 1400 they are crossed at half that, 8k. It would be interesting to see the curve to get an idea of what would be possible. I will measure my units later and it would be good to have someone else’s measurements/ideas to compare with.
I will use the JBL045Ti’s on K2-S9800SE horns with JBL2451Be and 2332’s below. All ideas and information is much appreciated. My basic idea is to crossover at 1200Hz (2332 does not go very much lower) and 10kHz in an active setup.
Special thanks to the fellow forum members that helped in sourcing 045 drivers, 9800SE horns and 4” BE diaphragms. Thank you.
Also, does anyone know the polarity of the 045's? The have flat connectors in the back and one is wide and the other one is narrow. Which one will cause the diaphragm to move towards the front with a positive voltage applied to it, ie positive polarity. On the "normal" compression drivers this was the “black” terminal. My 045’s does not have any markings on them.
All the best and thank you
