The Scan-speak 15M/4531K-01 5.25" Revelator midrange features a slit-paper non-resonant cone and dust cap structure, dynamic linear suspension, SD-1 magnet system, "Grasshopper" cast chassis with maximized air flow, glass fiber voice coil former and resonance terminating mounting system. The 15M/4531K is intended for use as a midrange, with a usable frequency range between 100Hz and 6kHz. As you can see from the response curve, this speaker has a lot of energy in the upper frequency range.
