beryllium vs the best soft domes

Yes, it's very easy to fall into the trap of listening with your eyes. It's why one of my mantras is 'I trust my ears. I don't trust my brain not to be fooled, or fool itself'.
I do like a good beryllium dome tweeter though. Although I like good soft domes, ceramics, aluminium alloy [etc.] too.


Indeed. I try to mainly choose drivers that fit the job. If they have "errors" like a bad breakup. I mostly look into wether or not, it's something I can work with. For example. My midrange is an 5" alu. It has it's first breakup at around 10kHz. I cross around 2kHz and since I run it active. It's easy for me to fine tune.
If it works... it works 😎
