Default Measuring a loudspeaker close to a wall

I've taken some measurements of an in-wall speaker I built. The measurements are taken at about 5" from the speaker. The speaker and the microphone are about 18" away from a side wall. The speaker measurements consistently have a hump in them from about 300hz to about 500hz, peaking at 400hz, with a magnitude of about 5dB. I did some calculations and it seems like the the wavelength@375Hz is ~36" (2 * 18"). Is this causing the peak in the measurement?

I liked it just fine, however, it didn't answer my question. I will probably try this after I install the drivers in the baffle again (i'm taping and paint it into the wall presently). I posted it here to get additional insight from users who may frequent this forum, but not the other. Did you care for the reply? Any additional insight to offer?
