The Theater Series four π Speaker is marginally more efficient, but the Thermionic four π goes a bit deeper. The Thermionics have a different damping value so they sound fuller, and the midrange takes on a slightly different character too, having a sound that I would describe as vintage tube sound. But they are very large.
