Is the Maelstrom-X really worth the money over the IXL or SDX15? I am getting ready to start construction on my dedicated HT room and trying to figure out the sub situation. I would really like to have 120+ db's at 30hz but I have Magnepan mains and really need a good SQ sub at the same time. I want to have my cake and eat it to. :bigsmile: I would like to stay under 12cubic feet per enclosure and I was planning on one in the front of the room and one in the back. Any advice would be AWESOME!
