Hi guys,
As some as you now I recently got my hands on two tractrix horns with a Fc of 220Hz. I'm planning to use them from 500Hz upwards, crossing over to a 15inch Ciare Woofer. There are several compression drivers that could be interesting, I'm sure some 1.4 and 2'' drivers will go down to 500hz, but I figured that 1'' most prob. will have better HF extension. So, What about the Altec 902 (or GPA 902 or 909), can it be safely crossed (2nd order) at 500Hz for home use? Or maybe some other 1'' drivers that can pull this off without a problem?
cheers,
Jacob
