I have the seas' with magnesium cone material, big heavy solid copper phase plug. Its not a tube friendly speaker, at all. Rates like 87db and will suck most any tube amp dry.
My Jadis Orch Refer does bring dynamics to this speaker, amazingly. Jadis makes the claim their amps, even the baby of them all the Orch, will drive any speaker. And its the truth. I hooked the Orch up to a huge thristy Mirage 1 speaker and she managed, though for how long under that stress? btw the JOR has KT90's, a tube that to my ears gives the best overall balance in bass, mids, highs. The KT88 is not a tube for me. The dynamic separation is just not there.
From my experience I agree that paper is most ideal.
I'd consider 3 speakers for most any tube. Cabasse's 2 lines, primarily their top line with the white cone (foam)material. Also any spaeker with the Scan Speak paper drivers. There are several labs that use these, ProAc is one.
But I never cared for any propylene(plastic) style drivers. They still seem to make drivers with this outdated material.
