I also have 2 Rockford 12 " P3 's and 2 Rockford 10 " P3 's in boxes . The 12 's I will let go for $ 400 . The 12 's are less than a year old and retail for $ 650 . The 10 " speakers are in a sealed box and I will let go of those for $ 300 .
According to the above context, answer the following question.
What may be the reason why the speakers are in a sealed box ?


They did n't need them after they bought them .
