the Mezzo Convergent Synergy to be raised about 1”. This is because the effects of comb-
filtering are more noticeable the further you are away from the Mezzo Convergent Synergy.
This comb-filtering reveals itself as a slight nasal sound in the voice. If you notice this in
the sound, you should raise the front spikes of your Mezzo Convergent Synergy. This can
be done by removing the front spikes and replacing them with the spike assembly as shown
in Figure 14 above. Do as follows:
• Screw the spike and nut into the diode.
• Screw the 3/4” setscrew into the front spike holes in the stand.
• Thread the spike assembly onto the set screw.
Resetting the Propagation Delay correction (PDC)
Once the final rotation has been determined, you will need to reset the PDC. If you
have raised the speaker by adding a diode or 1/2” spacer, read the PDC from the table that
matches your current spike configuration in Section 10.
Every system has a unique time and phase character, which can affect the PDC ac-
curacy. Because of this, you may find that sliding the tweeter forward or backwards one
or two positions increases the clarity and correctness of your Mezzo Convergent Synergy.
If you like, experiment with the tweeter position and lock it in position when you find the
location you feel to be most accurate.

the Surround channels so they match in level with the front channels.
