The 4343 is a classic and has an unmistakable stamp on the classic JBL sound..nothing wrong with that.
The 4344 used improved/later developed drivers and an offset baffle driver configuration and refined crossover network. All that adds up to improved imaging, smoother character and more power handling under certain conditions.
The 4345 was an eighteen inch woofer version of the 4344 using the 2245H woofer (which was the ultimate at the time). This provided slightly improved sensitivity and greater low frequency output, perhaps the only flaw in the 4343/4344 in my practical experience in the professional arena. To the ear the 4345 voicing is otherwise identifcal to the 4344 but can convey a greater sense of authority at low frequencies, its also twice as big.
The brochures spell all this out well enough.
Regards your own system try and find a member locally who has the 4343 and get an opinion. The 2215 as I vaguely recall may not have the deep extended bass of the medium efficiency 2231A/2235H/2245 woofers. I can't comment on the driver horn combo or the 075.
No doubt it works , if your ears like the presentation then your on target.
Sit back, play the music and enjoy. The real key to these 4 way brutes is setting them up properly, adjusting the pads correctly and using complementy equipment.
