The JBL 2241 and 2242 have relatively low Zmax - just like the 2226 does. They're all about 60 ohms at resonance in free air, which makes the in-cabinet peaks about 30 ohms. That's good for tube amps and so any of those one will work very well for you. Not only is the impedance curve pretty benign but the cabinets are overdamped, which makes them tolerant of higher output impedance and other causes of eletro-mechanical parameters shifts, such as voice coil heating, environmental conditions, etc.
