I just wanted Ron to clarify what he is doing, i have never heard the term "woofer cooking" before.Why not? You can also listen to speakers with different driver manufacturers and in the end it works wonderfully. It's no different with amplifiers, adjust the volume, pay attention to the phase (measure then it works. I've been doing that for years, for example in bass, always with transistor amps, they simply have more control and a higher current delivery capacity for a bass driver.
