I feel that the kc62 is all about really small rooms in Asian market, and they have the larger version for any larger rooms when space is available.And no doubt it will sound quite impressive in the smaller listening room setups that are likely to be typical of demo rooms.
As KEF is now owned by Hong Kong GP acoustics it’s reasonable to produce something like this which sells like hot cake here. Apartment size and cost will blow away minds of most ppl in the west. My “flat” size is similar to the bedroom of my brother in law in Germany, and cost three Times as much, so u could imagine in the local market most listening room size will be about the bathroom size of a typical European or American house. Which means almost impossible to put a 12” driver sub.
