The 034 is the plastic version of the cast aluminum 044. It was used in the L15, L46, L56, and L86 systems. The 035Ti is the plastic version of the cast aluminum 044Ti and it is used in numerous Pro and Consumer systems.
The 034/044 used phenolic diaphragms coated with aluminum and they are "good" to ~ 15 kHz and ~ 18 kHz respectively. The 035Ti/044Ti used titanium diaphragms and are "good" to ~ 25 kHz and ~ 28 kHz respectively. The difference in response is supposed to be due to the plastic versions having ~ 1/2 pound less magnetic material.
