Hi guys, thought some of you might be interested in a little get together we had this weekend. Four Aussies got together on a sunny saturday, measured some compression driver + waveguide combos, set up active crossovers and listened to about 7 different versions with some dynamic torture tracks that will quickly show up any amount of harshness.
We tried two different oblate spheroids, a few econowave type waveguides (18 sound XT and a JBL lookalike) and a few popular compression drivers - Faital pro, B&C and Selenium.
Measurement setup:
We measured them and Andi put together some directivity plots like this:
You can see the summary here:
Or some of the comments in the original thread:
We plan to do some more, this is just the beginning!
At the end of the day we also compared a dome tweeter. There was an obvious difference but the group picked the compression drivers. It was an enjoyable day, especially when someone else is taking care of the techy side of things!
