Aluminum in 2446, which diaphragm should I get?
^ YW! :)
---
Just read Truextent's white paper on beryllium vs aluminum vs titanium vs ribbed titanium in large format compression drivers, and was quite pleased to see the performance of the aluminum diaphragms. My 2446 drivers are using ribbed titanium now and looking at the spectral decay in those measurments I think it's quite clear why they are a little hard sounding. The paper seem to favor Be in applications where you're going to boost the high end because of more output and smoother response, but the decay plots indicate that if you're going to use this driver between 1.5-8/10khz range you get very uniform decay with aluminum. This is great news as they are not that costly.
What aluminum diaphragm would you guys pick for 2446? Wanting to stay clear of ribbed ones judging from the paper.
Is Radian 1245-8 Diaphragm worth giving a shot?
