Dispersion characteristics
The graphs below show dispersion angle over frequency of a single
Q10 cabinet plotted using lines of equal sound pressure (isobars) at –6
dB and –12 dB.

Note: Please note that in the standard upright configuration the Q10 has a
very accurate 110° horizontal constant directivity behavior that is
maintained down to approximately 800 Hz, see Fig. 5.
This performance differs considerably when the cabinet is deployed
horizontally with the horn rotated. Fig. 7 illustrates this and clearly shows
the narrowing of the horizontal despersion below 1 kHz as a result of
the dipole arrangement of the low drivers. Extreme care should
therefore be taken when the Q10 is configured in this manner to ensure
adequate coverage is obtained.
