Favorite Tube Speaker Match

Triangles. They are tipped up in the treble which makes a good match. And very efficient

i have had all materials, and paper sounds the best to my ears. I have used tube amps from McIntosh, Dynaco, Berning, SET's, PP, you name them, and the I just am drawn at how natural and dynamic in a good way the paper drivers sound.

I dont think the material that makes the magnet is as impoartant as people wants us to believe. I also had all kinds of magnet types..ainico, ceramic, neo...etc

Well, My favourite combo is Bozak B-410's driven by a Berning EA-230 triode amp. After that comes EV12trxb's driven by 2A3 SET's.

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 They still seem to make drivers with this outdated material.

I can always tell a difference in magnets, but I have never done a "pull the speaker out of the system, plug in a different one with different magnets" test.
