Most likely door resonance. If you don't deaden doors, you end up with large resonances in midrange. Usually you'll have trouble in lower midrange (300-400hz range), which gives a deep, resonant, almost boomy quality to vocals, and also usually between 1-2khz, which can be very fatiguing. You also have to take into account the sonic hole you get with off axis door installs, to the drivers seat, usually your side door will begin rolling off between 1-2khz. That will kill midrange quality, especially with sets like this one where the midbass driver is crossed over around 3.5khz (if I remember correctly, I know it's upper 3khz region). There isn't a whole lot you can do about it without having the midbass driver more on axis. The midbass driver itself is good to 5khz.
