Pi² + 0.1 – It's 9.88 [$75'000/pr] or what Voxativ of Berlin call their expanded monitor/sub stack via a central upper-bass coupler with three response contours selectable by jumpers. The triple stack combines a rear-horn-loaded AC-4NP widebander on top with the twin-woofer Ripol bass module at the bottom joined by the 0.1 rear-ported mid module [$17'500 add-on]. As shown, this now better matches cosmetically in the rear than early show sightings of pre-production samples had suggested.
