Comparo thoughts on a couple CD's

[wrager]

What are you're thoughts on a 2447h with the Radian al phragms versus a 2430h (or 2431)?
I guess it comes down to the 4" vs. 3 " phragm and whatever phase plug differences there might be.
I will say, I don't like the slight harshness of Ti phragms (2432). I have the following horns: 2384, 2352 and PT95's.

The radian diaphragms go lower than jbl titanium. It will sound nice with something like jmlc-270

Most probably you are being ignored because you talk about non JBL products.

Most probably you are being ignored because you talk about non JBL products.

Well,, not that many people here really have the need ( or desire ) to place non-OEM diaphragms into their JBL ( or Altec ) drivers.

Here's one exception ( driven by the hard fact, that aftermarket is the only choice if you want an aluminum diaphragm ) within your 2482 driver .

- Note the "High-Q", 60x30deg horn ( along with RC network ) is "boosting" the HF .



I have yet to put these into action ( therefore, I have no opinion on their sonics ) .

Frankly, I was very pleasantly surprised at the overall extension ( & linearity ) these diaphragms offered after I put them put into my ( very first pair ) of large-format compression drivers ( which I purchased way back in 1977 ) . Still don't know if these will knock my beloved 288-8K(s) off their perch ( of my go-to driver ) .

The 2431 is a very nice driver / the only knock I have against it is that it's a weak performer below 1K ( & over 10K ) . From 1K to 10K , it sounds wonderful !
