Hey guys, couple of questions for you. I'm going to build one of these two boxes, and I need a little help choosing which one. I like the little extra extension on the Adire, but I also like the extra spl of the SBB4. How much of a loss in overall output is there between the two? Could the port be "adjusted" to lower the tuning on the SBB4 to allow some extra low end? I'd LOVE to build the Shiva EBS, but I think the box is a little large for me. Well, any tips would be greatly appreciated. Chris By the way, this is for HT use only, music will be very minimal.
