mboxler Posted September 24, 2022 Share Posted September 24, 2022 I was interested in the voltage transfers of various filters across the K-33E mounted in my Khorn. I was surprised how much the voice coil affected the A and AA transfers. Green A and AA Black AK-2 Red AK-3 Brown AK-4 If anyone knows the difference, if any, between the AK-4 and AK-5 I can measure that as well.

Schu Posted September 24, 2022 Share Posted September 24, 2022 where is this leading us? Quote Link to comment Share on other sites More sharing options...
Deang Posted September 24, 2022 Share Posted September 24, 2022 Would actually be result of VC and filter combined, right? Quote Link to comment Share on other sites More sharing options...
Klipsch Employees Trey Cannon Posted September 24, 2022 Klipsch Employees Share Posted September 24, 2022 You need to use a 4 Ohm resistor in place of the woofer to see the VT of the net... Dean is right, you have VC and filter. 1 Quote Link to comment Share on other sites More sharing options...

This is the voltage across the K-33E installed in my Khorn, connected to various filters. Wouldn't the horn loading also come into play? 1 hour ago, Trey Cannon said: You need to use a 4 Ohm resistor in place of the woofer to see the VT of the net... Dean is right, you have VC and filter. Am I wrong thinking that the driver is a part of the network? If I were to use a 4 ohm resistor in series with a 2.5mh inductor, the plot would end up with a corner frequency of 255Hz, and then drop by 6db per octave after that. That's not what happens across the woofer terminals when using an A or AA, as the voltage drops less than 3db per octave due to the inductance of the voice coil. For some reason I found this interesting. 2 Quote Link to comment Share on other sites More sharing options...
