Yes, I know there are many other threads with this title. But this one is new

I've been using the stock titanium diaphragms in the 2445Js with the 2380 horn. It sounds absolutely magical. Over the years, I've had many compression drivers and many horns, but nothing sounds like this. I also have the BMS 4590, which is a state-of-the-art 2" exit dual diaphragm coaxial driver. While it sounds more refined, especially in the last octave, the 2445/2380 combo has holographic imaging, with a tangible feel to instruments, speakers completely disappear, and music actually sounds like being played by people. It is not the crossover because I'm getting good phase overlap with both drivers with the woofer, and I also use FIR correction, so the tonal balance is the same in both instances. The 2445/2380 is just better.

So, I'm wondering if I should splurge on the Truextent Be diaphragms. Other recommendations include the aquaplas "SL" versions of 2450 diaphragm. But I cannot find those in stock anywhere, not even on ebay.

So, got any recommendations about what to do?
