Olive oil un-virginer
Well, I was thinking about using the JBL 2440 drivers in my front stage. They just need $17 diaphragms. I've done a bit of research on the concept of horn use in audio, but I am still a novice.
The 2440's have a metal adapter in between the driver and the large flared fiberglass horn. I see a lot of car audio horns mounted in the "knee panel"
That seems to go against my prior belief that your high frequencies should be coming from higher up for a good sound stage. My previous belief was that tweeters should be mounted high and wide, like the lower A pillar either on or off axis
Why are horns mounted so low?
I have also seen tweeters mounted in the dash pointed up at the windshield to disperse sound. I was thinking about mounting the 2440's like this because it would be the easiest. I have plenty of space in my dash after gutting things. Should I buy new horns for these drivers?
I'd really like to use them. They're super beefy with a 4" voice coil on the diaphragm. The drivers are solid steel with a neo ring. I have the amplifier and headunit capability to adjust phase and frequency rolloff. These would be coupled with 4 sundown neopro 8' in the doors.
Suggestions/advice?
