Concrete & Beryllium speakers powered by Devialet Expert

However, looking at the response curves you shared I cannot stop wondering about the reason why you selected to cross over so low in a region where the beryllium tweeter appears to be more than 7dB below its flat zone which seems to start around 800Hz while the woofer does not seem to exhibit any accident before 1000Hz?

Was it to avoid the transition to happen in the 300 to 3k Hz band where our hearing is the most sensitive, or was this because of other considerations not visible in a simple graph?

Thanks a lot,

Good question Jean-Marie,

I did wonder also, replying here.
It is a long time theses speakers has been made. I should probably ask the accoustic engineers involved in the project to better understand this choice. I was quite new in the audio world at that moment and I did follow without getting everything.

Let me get back to you after some verification.
