I've been running a pair of these at home with 375s for 20+ years now. I love horn dynamics and I love how transparent and invisible the 2397s are. Just recently looking over the JBL literature I noticed it says the results were achieved with the 2440 and vertical coverage is nominally 60º with a cylindrical baffle.. I've just never seen anyone set these horns up with a baffle, including myself. Mine have always just sat on my Harkness boxes with a bit of downward incline, as I saw when I first set them up that the flattest response was measured at 30º. Closest I have seen to use with a baffle is the Westlake monitors with their iterations of the Smith horn, but that is also not a cylindrical baffle.How do we suppose the output is affected by use without a baffle..? Less than the nominal 60º of coverage using with the baffle gets presumably? Does anyone have a picture of the recommended circular baffle setup? I searched online without luck.
