I don’t really understand why subs need to be "paired" with speakers.
Doesn’t the question come down to sub type, room size, style, and price?
After all, most subs will be able to assume the burder of reproducing frequencies below almost any speaker. That means that the fundamental question at stake in a choice of subwoofer has nearly nothing to do with speaker type and nearly everything to do room acoustics. This is how I’ve understood the basic situation.
