Frequency response of SIX flush mounted and slightly offset on a simple 10 inch wide baffle with 500 Hz second order LR filter and recommended response shaping circuit.

The ribbon works well with a range of filter values and baffle sizes, resulting in smooth roll-offs at the frequency extremes, easy transition to low frequency drivers, and a natural upper octave energy in real-world listening environments. If desired, manipulation of the upper octave response is easily achieved by small changes in the response shaping circuit.

(Instructions are clearly presented on SIX's back label making this important aspect of high performance reproduction an easy affair.)
