What base enclosures would ba a match to MR94 horns

[yelmite]

Hello all,

I have a pair of 291 drivers behind MR94 horns with Speakerlab K's doing the LF and EV T350's picking up the HF. The speakers have an active crossover. I am not thrilled with the K's as there is a huge built in cabinet for the back that is not optimal for the folded horn design and rattles a bit. So, what LF enclosure and driver would integrate best with the MR94's? I recently picked up a pair of 620 enclosures and was wondering these could do the job with the right driver or maybe a couple A-7 LF enclosures or something JBL or a decent sub or ?
