Greets!

The vent is a 1/2 WL resonator with its own harmonic structure activated by the 1/4 WL pipe's pulses, creating a very non-harmonic summed system as clearly shown in the 'woofer and Terminus Far Field Sound Pressure Level Responses' plot. Driver and/or vent locations away from the ends just screw it up more.
