That's really interesting, maybe a call into SEAS is in order. On specs alone, it looks like the breakup frequency got pushed up 1.5K, which allowed Jeff to push the crossover point up from 2K to 2.5K it seems.
As for Pearl vs. Perspective/Pulsar, it's a good point that Pearl is a true 3 way with dedicated bass units. That being said the midrange is often the most critical for tonality, so a meaningful upgrade in that region would still be great. The SEAS Excel W18EX003 driver costs about $1000 a pair, but the upgrade costs 5x that much, so really want to get a sense of how tangible the improvement could be.
