Most interesting, to see the photo and what appear to be new driver mounts, as first seen on the 8K anniversary model.
This advance is also mentioned by Bob Stewart in the promo video. So an upgrade to previous versions would mean all mid and bass drive units would have to be refitted in the cabinets. Quite a big mechanical job in itself never mind tweeter change and the electronics boards upgrade.
Interesting times ahead not least dreaming up a credible story for SWMBO.
