Cool, then just quickly in my head it should couple pretty well up to the 600Hz area. Assuming a ballpark from the center of the horn? Would that be right? I really need the extra 300Hz to 100Hz so that would be okay...these things have no problem producing 1.5kHz and above with 22 tweeters.... and I am already taking a dip out around 600Hz.
Thank you guys for the help
Let's do a little math. 600Hz is 1.88' so 1/4 of that is less than 6". Is that the spacing from the center of horn to center of horn?
Let's think about tweeters Lets say 10Khz is your top freq . That is 1.3" Is that the center to center of the drivers?
As you go up it gets harder and the spacing has to be smaller. It is NOT spacing between edge to edge-but rather center to center.
Also the 1/4 wavelength is a "guideline" not a hard and fast rule that it either works or doesn't on either side of that.
