Has anyone ever dealt with a resonant engineering se 15'' sub before? Im thinking about getting one. I have a 600 watt amp to power it. Only problem is they recomend a 1.5 cft seald box. I have a 3 cft seald box. Do you think it would be ok in such a large seald box? I have plans to port it later but as of now im going to have to go seald. how loud do you think this thing will be? will it sound decent. Would it be louder than 2 pioneer 10's off the same wattege?
