Currently I have 1 fi spy 15 in a 5cf box. I might be able to trade for 2 sundown x 15's and my question is which will get louder given the proper box for both. the sp4 is rated for higher power but I would have more cone area with the x's so this is where I'm confused. I just want to know if it is even worth the trade for me. This is NOT a vs thread I just want to know which will be louder in the proper application. Thanks for the help
