There is no question that these are very disturbing times, yet, that just makes it more essential to continue some planned design studies based on newly available products and, let us just say, popular older concepts.
There is considerable chatter about the new Epique woofers, and even some detailed test data for the E150HE-44, but there are many open opportunities for system builds yet...
A common issues with the current crop of long throw small diameter "subwoofer" drivers is the difficulty of creating a small optimum design, considering that the T/S parameters largely dictate using a Helmholtz alignment of some type to get extended low frequencies without EQ, but the box sizes and port air velocities render conventional ported approaches essentially unusable, unless the esthetics of a pot bellied stove are appealing to yourself and your significant other...
Which leaves consideration of passive radiators as another possibility...
The RSS265PR suggested by Jonmarsh certainly provides adequate performance, but is not conducive to flexibility in enclosure sizing.
Another interesting if obscure alternative is the Wavecor PR223BD02. Two of many possibilities are shown below...
Relatively maximally flat, in a 20L enclosure...
A tapered extended response alignment, in a smaller 15L net enclosure...
Of course, this is only a start, and leaves unanswered many questions about a possible system confirmation. note, that while the upper range is reasonably smooth and HD2 is low, I would not consider this a good candidate for a conventional two way... though with a waveguide loaded tweeter, that could change.
