I’ve updated the Sequence Two – Monitor design with a ScanSpeak “Beryllium” tweeter version for those who wants a super expensive and exotic hard dome version! 🙂
Basically it’s the same design, but with minor tweaks to the cross-over. The ScanSpeak “Beryllium” and the “Textile” AirCirc dome tweeter is essentially the same driver and can be regarded as drop-in replacements for each other.
Sonically the “Beryllium” version has greater transparency, reveals additional micro-details and is a bit more analytic in its character compared to the “Textile” soft dome version.
