Tonal Profile
A dynamic woofer with balanced armatures above it, crossed passively. The 15 Ω nominal is the lowest of the Letshuoer line here, and the crossover means the real impedance curve is not flat — output impedance in the source will tilt the balance, not just lower it.
What the datasheet actually says
Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.
«Sensitivity: 102dB»
The same bare «102dB» stands on three Letshuoer pages that describe different transducers and different loads: the S12 and S12 Pro planars at 16 Ω and this dynamic-plus-armature hybrid at 15 Ω. Only the S12 page names a unit («102dB/mW»). One figure repeated across topologies is not evidence that they sound equally loud from the same source; it is what a specification looks like when it is copied rather than measured per model.
