Family scoop, modern magnet.
The C12K-2 carries the classic Jensen scoop into the modern-magnet era — low-mid cut, borderline Glassy presence rise, but with a bite that reads chimey and defined rather than piercing. The top end fades gradually rather than cliffing. Less peaked than the C12R or P12R, less neutral than the C12K — a middle position, keeping enough family voicing to be recognisable while the modern magnet reshapes the peaks into positive character labels instead of harsh ones.
