Ok, almost have my table saw cleared and speaker test stand back in place. As I have mentioned elsewhere, I have a few drivers already and am contemplating how to deploy them for many options to suit different needs. First of all, do not expect to use any drivers much larger than 8-inch ones. I simply do not have the inclination to deal with building boxes that large. That said however, will use multiple drivers to move enough air to energize most medium to large rooms. All current plans are for these modules to employ active crossovers. As with Directiva, likely these will be minidsp 2x4 or better. Expect the filters to be simple enough to be used with other active crossovers too.
I mentioned in the main thread that I want to consider how bass module might be deployed as a traditional monopole and also as a cardioid. As testing the cardioid will be easier outdoors, the monopoles will come first as weather here will not allow much outdoor activity for a few months. 
One major consideration for these bass modules is height. Unlike a subwoofer, they are intended to support having another speaker on top of them. For either an r1 or r2 speaker, those cabinets are around 14-16 inches high. One plan is to use the Denovo tower for a bass module cabinet, it is 34 inches tall. This would put a tweeter at around 44 inches high. At my seating height on my family room couch, this is about right. Slouching a bit, it is a bit lower, so plan to make the larger cabinet a little shorter. If it has a plinth, may need to be even shorter still. For right now, the cabinets are cut to around 32 inches high. In case you missed, the initial drivers used are:

- Dayton Esoteric woofer(s) in the Denovo tower cabinet.
- Dayton RS225 woofer(s) in a larger custom tower.
