I believe that these devices use a similar idea to the Copeland (which I've never heard), but the distinction (I assume) here is that either of these units will sit between your active x-over and the bass amp only. The rest of the system's bandwidth above the bass driver's x-over point is completely unaffected. Conceptually, there's still a trade off between "purity/transparency" in the range below your bottom x-over point due to the extra device in the signal path, but - in my experience - I've found that the benefits from smoother FR and precision level matching at the x-over point completely overwhelms any such costs.
However, this my own judgement and I am 100% sure that some others here would/have come to the opposite conclusion....the old YMMV.
I mention it because I'm a believer and because your set-up with active tri-amplification lends itself to the approach without involving the mid-band (or above).
