Week 8 was the last week that test were being carried out for the speakers.  During this week the blind study was completed.  In the first sample of 15 people, 9 preferred the MDF cabinet over the Oak cabinet.  These results did not show the significant favor towards the MDF cabinet that was expected, but was fairly consistent with test results of slightly straighter frequency response from the MDF cabinet.  Another sample was taken with 24 different people to attempt to get more conclusive results.  This resulted in only 7 people preferring the MDF compared to the 17 that preferred the Oak.  The second sample shows a 70.8% preference to the Oak, where the first sample shows a 60% preference to the MDF cabinet.  These tests show that listening tests are very subjective and a person's preferences might affect the data.  For example, if a person likes a lot of bass in their songs, they will probably gravitate towards the Oak cabinet because of the slight boost it has in the lower frequencies compared to the MDF cabinet.
