Peak power handling is at 250 Watts, with RMS power handling at 125 Watts. This is made possible by a larger 90 oz magnet structure weight working with the same 1.5 inch high temperature CCAR voice coil as the FX6m4 has. The larger size also expands the frequency range slightly to go from 100 Hz to 11 Khz, offering a richer sound experience. The larger size means a deeper 2.6 inch mount depth, which is still slim enough to fit into car doors but won't fit into as many tight places. Vibration reduction is handled by a high tinsel steel basket, and a bass blocking capacitor is prewired to prevent frequencies outside of the frequency response range from distorting the sound.
