I do this, using two M&K mx700 in stereo with high pass filter set to 40hz, no low pass filter on the Monitor Audio speakers, and a M&K v200b sub with the high pass filter set as low as the dial can go - not real sure but id expect below 30 hz. the two 700s are stacked vertically.
these three have really helped my 10x11’ room suffer minimally from pressure nodes and it goes as deep as any material i have to play.
