Hello, I'm new to the forum but a veteran on a couple other forums. Just purchased a pair of 2404H baby cheeks. I am upgrading some Khorns using the JBL horn drivers. The original tweeter is a EVT35 style and has a 104db sensitivity. Now the 2404H has a 105db rating which should make it hotter, it is not. After removing the lense, I found an aftermarket pair of diaphragms. Could this be the cause of the low output? The DCR is about 6.4 ohms which tells me these should be 8 ohm impedance. They look exactly like THESE on ebay with the same number.
Connected to my networks, both are at least 3-5 db down from the K77/EV T35 tweeters.
Are the generics that far off? I have some test equipment to verify this but its obvious the output is much lower.
