The M6a doesn't really have a significantly higher working range than the M8a. For that reason, a relatively low steep crossover is advised, and that implies a tweeter happy playing down low. First bang for the buck suggestion for that role would be the Seas 27TDFC, or the aluminum version if you like metal with your metal, the 27TBFC/G. Of course, there are many other possibilities; for a more polite but very resolved sound, the RS28a is recommended.
