Børresen speakers have an inherent response that compensates for the Munson/EL curve.
Klipsch Heresys are also pretty good for such dilemmas, but they lack some refinement relative to others, and require tube amps to sound best.
Another good option might be a powered speaker with onboard DSP such as the KEF LS50W or LS60, which will mostly allow you to tune the response to taste, without the drawbacks you get from conventional analog tone controls.
