You're usually the last person I would argue with. But going from one sub to two I would argue that two are better. I think the key thing is the mutual coupling that happens between the sub and monitor speaker. It brings in another dimension to the speakers sound.

I said excellent results can be had using 1 SW. I was definitely not "knocking" 2 SWs.
When you are as space constrained as I've been, for many, many, years, you learn to make things work well using 1 SW.
A 24 dB./octave Linkwitz-Riley crossover is in phase at the "corner" freq. That is very important, given the abrupt transition from "satellites" to SW. Of course, the crossover is electronic and the rig is multi-amped. I was fortunate, in the past, to have enough "folding green" to work around the space issues. Dash it all, there is no escape from TANSTAAFL.

I just stacked the monitor over the sub simply like an old fashion three way speaker.
The key is to have a decent plate amp. A good plate amp will help integrate the sub/monitor combo much smoother.
When I had the original Paradigm plate amps I never was able to get a good smooth transition. after I bought ONE Keiger from Madisound that sub sounds smooth. The other Paradigm with the original plate amp doesn't work well at all. So I do plan on buying a better plate amp for that one.
The trick with subwoofers is you have to have them do as little as possible. Strange but true.
I used two subs 15 years ago using expensive Peerless 10" subwoofers and two Parts Express 120 watt plate amps. It sounded ok, but I suspect the plate amps were not best quality.
Now a days, the newer Parts Express 10" subwoofer is better sounding than my old subwoofer system. The 10" subwoofer is faster responding than the Parts Express 12" subwoofer and sounds better as I owned both. You would have to spend a lot more money (perhaps 5x) to get a better sounding subwoofer.
10" does appear to be a magic number for woofers. Of course there are bigger woofers that sound great, but they tend to be the more expensive ones.

I've also found that a powered 10" sub is ample size. That plate amp is busting a nut to crank out a 30Hz tone. Saving your amp and speakers from that nastiness.
Every 10 Hz lower brings a whole new set of problems and a smaller groups of recordings that have any sound down there.
