I had them leave the sub off my RM30's.

Nice lookin' speakers and not too shabby of a low end for full range. I would definitely want to get rid of the hugh hump between 45-90hz. I don't think you could trap the bass that low... would be a lot of work. Surely those speakers can be bi-amped.... do you have them bi-amped? You might try switching the phase on the subs and see what happens.
