D220Ti omf Passive Crossover
Blue trace below (Fig 9) is the frequency response
of the D220Ti with a Passive Network. The Violet
trace is with the Synergy crossover at 1,500Hz.
9 - Selenium D220Ti with Pyle PH715
- IV Response with Full Passive Network
Blue traces in Fig 10 show the M8a and the D220Ti
crossed at 1,500Hz. The Red trace above is the Summed
Response with the D220Ti connected in Reversed Phase.
The Orange trace is when the D220Ti is In Phase.
It is important to connect the compression driver
in Reverse Phase otherwise there will be a deep
notch at 1,500Hz. The Red and Orange traces are
displaced for legibility.
