Couldn’t find too much on the miniFit Detect speakers. The Philips 9050 Whitepaper says:
New miniFit Detect receivers support a wider frequency bandwidth, from <100 to 10,000 Hz, to give a fuller listening experience for entertainment and music; on top of that, they identify left or right side to make receiver replacements easier.
