Has anyone here set up a system with tiered subwoofers handling different bass spectrums?

Has anyone here set up a system with tiered subwoofers handling different bass spectrums? I currently have bookshelf speakers fully crossed over to a pair of smallish symmetrically placed, force-canceling stereo subwoofers at 160Hz, and I am thinking about adding a big, ported sub and fully crossing that over to the stereo ones at 60Hz. My setup will easily allow me to do it (I have a miniDSP Flex that is applying DIRAC Live room correction to my current 2.2 setup downstream and that preamp is handling the full bass management duties right now, so the miniDSP only sees a pure 2.0 system at the moment--I can just attach the new sub to the second pair of outputs and use the miniDSP to handle this level of the bass management). Am wondering if anyone else has tried this? I am looking to improve bottom end impact and extension with the big ported woofer (looking at SVS PC-2000 Pro) since the stereo ones are not currently reaching down as low as my previous sub (currently a pair of SVS 3000 Micros; before these, I had a single SVS SB-3000).

I do, but I don't use the subs for music.

The Yamaha RX-Z9 feeds a dBX subharmonic booster and this feeds a Crown PSA-2XH in bridged mono mode producing ~800 WRMS into the 12 ohm load of the 15" JBL W15GTi.

 

But even this doesn't go down as far as my Sunfire Signature and on the second receiver sub output, this is used to fill in from <20 Hz - ~60 Hz using the internal filter.  The levels are set using an RTA.
