Hello! Today i made the first test of the JBL 2344a vs 2370a with almost positive results (2425 drivers) . Definitely less distortion, definitely more accurate, definitely less efficient, definitely less musical. I think that 2344 is a horn that will not work correct out of the box especially in a 3 way speaker system. I have to add an l pad on the 2404 tweeter to match the sensitivities of the horn and tweeter (something that is not necessarily with the 2370 that cover the tweeter nicely), also i have to add some gain to the comp driver from the crossover to match the woofer. Generally is a flat sounding / accurate horn that makes it ideal to mix but not enjoy music. I think also that is sound stiffer than the 2370 in midrange freq , 2370 is smoother . Also the stereo image is more in middle than spread around like with the 2370. Anyone that got more experience with these horns??
