*Please note : Customer assumes responsibility for power testing each design per application. Eminence Speaker LLC does not power test samples. The ratings above
are a general guideline based upon known thermal capacity of voice coil diameters/materials. True power handling depends on many driver and system factors, thus
our guidelines are conservative in nature.
