Figure 2.1: Shows the complete system anechoic on-axis response. The LF response is tailored to fall off below 200Hz matching room gain.

Figure 2.2: Shows the system response with the measured phase. The phase shift up to 300Hz is well behaved, above this the phase is essentially flat within ±15 degrees.
