I dont have any experiance with the driver you mention. There a few guys out there that dont like titanium diaphagm compression drivers. Some find then harsh and metalic sounding. Altec used a lot of aluminum and JBL did on older stuff. There is still a preference by some people for phenolic diaphragms in the mid-vocal range. It's been said that titanium was used mostly to increase durability for the pro's who popped the aluminum units like party balloons, and to help bring a higher extension to the compression driver. There was no way the phenolic was happy past 10k and in the upper octave it was a stretch for most of the aluminums. There are companies making the drivers today that use berrylium, aluminum, polyester and phenolic. I switched from the titanium diaphrams myself. Your milage may vary
