The Devores are another excellent choice.
I've heard the Zephrins myself FWIW.
Voxitiv should also do well, and if you configure the crossover properly, Pure Audio Project speakers can be 16 ohms. One version features the Voxitiv full range driver supplemented by two 15" woofers.
Coincident has been making higher impedance speakers for years- in fact they were designed with a set of M-60s.
