1.5" 2431H upgrade: should the 2435 BE diaphragm be the solution?

Hi Pos,
So are you suggesting that all of the throatless/short phase plug drivers(24**) aren't a good match for the M2 horn too? I ask as looking at the pics of that horn it has a very short throat before the pinch/slot section....

Hi cooky,

phase plug 'length', and driver internal horn are two different things.
4" diaphragm drivers such as 2440/41/45/46/50/51 have almost the same phase plug 'length', but 2452 has shorter one. I have no info about 243x types.
M2 horn has about 4cm long throat, so I believe can be used with JBL 1.5" drivers too (2447,2450sl/51/52)
