It would be worthwile knowing the frequency response to see if you need to adjust the frequency response of the Lowthers. I have DX4s on open baffle, and without a crossover, they were unlistenable (high frequencies were tipped up). Because of the weaker magnets of the PM6s, you very well could do without a crossover.
You definitely need a set of subwoofers, so tieing those in and developing a seamless crossover will be challenging, but very worthwhile.
The Lowthers do not have sufficient x-max for running wide open on open baffles. You should plan on high passing them with a 1st or 2nd order crossover at around 100 to 150 hz. It is good having 15 ohm drivers because of the greater x-max.
