The goal of this event was to have multiple subwoofer enthusiasts blind audition quality and relevant subwoofer pairs. Subjective comments were collected before revealing results to discover if previous enthusiasts' previous subwoofer meets of past have had built in biases that are not present in blind auditioning. Each subwoofer auditioned was required to demoed in pairs. We hoped to explore several questions listed below -- among others.
1) Can the difference between ported and sealed be detected in blind auditions?
2) Do enthusiasts favor one type of subwoofer design (ported, sealed, horn) over another in blind auditions for music vs. movies?
3) Are all subwoofer brand and design biases based on increasing cost effectively neutralized if auditioners don't know know which particular sub is being auditioned and voted on? Basically at a certain point are all subwoofers created equal?
4) Do capable sealed subwoofers with the ability to produce powerful subsonic make a recognizably positive impression on voting scores during blind audition?

EDIT: At request - to help show how each of these seats and thus their owner's votes were affected by their seat's unique frequency reponse please see the following post. I retested the seating positions post meet with my Captivator Pros to provide some guidance on interpreting blind voters' subjective comments, as the original graphs captured for each sub in post # 3 are simply an average of all 12 seats and do NOT represent what each seat heard. To determine what each voter heard you'd need to take the overall average and meld it with the particular seat to come up with a somewhat equitable idea of the frequency response.
