@E_Schaaf I love my dt-1350 supras for the practical reasons you describe as well as for their bottomless bass. My partner's Aventho are also great. So I am really interested in your new design. But it's kind of hard to follow the post without knowing eta or genesis. I tried skimming SBAF threads, but couldn't find anything that gave a clear sense of who you are today, what's been done and the reception. Could you give a little more background or point me somewhere with relevant background please? Just posting as others might be in the same situation.
