Jbl 2447 with aquapas dia?

[greg32]

As the title says, I have mint 2447 drivers and was reading about the aquaplas damped diaphragms, does anyone have any links to info or response graphs or first hand experience with the d16r2451 in a 2447 core? regards Greg

Here's a fellow who recently went to aquaplas coated diaphragms in a pair of 2446, so similar:

Thanks Jeff, i hadn't seen that thread. I have searched up lots of info on the aquaplas diagraphams but was hoping someone had first hand experience with the 2447 core and maybe even some comparative measurements. As I understand the aquaplas will be slightly more detailed less bright and more natural and slightly less sensitive. The thing im not sure about is if i will loose significant hf extension and require a uhf driver. mind you my hearing runs out at 15k now. Greg

The 2447 looks like a ferrite 2451 to me, I would take a wild guess and say the 2451 diaphragm should be OK in the 2447. I bet you could find some comparisons of the different diaphragms in a 2451 and use that as a starting point.

Hi Greg,

I've had 2447j with both titanium and -SL diaphragms and 2447 with -SL diaphragm sounds much better than with titanium ones. I also have 2450SL and in its turn it sounds (not so much) better than 2447 with -SL diaphragm.

No response graphs only listening impressions sorry.

Hi Alexander, thanks for the reply, if i may ask did you notice any difference in the hf extension between the ti and aquaplas diaphragms. regards Greg
