Naim speakers I would have thought extremely unlikely for the foreseeable future given the tie with Focal, but ‘boundary’ speakers exist, from on- and in- wall speakers by various manufacturers, and perhaps the most striking of all being the Xulyde MD1 and MD3 from Synthèse Hifi in France, which might strike a chord (pun not intended!) with people knowing the SL2 or perhaps SBL.
