I am currently looking into upgrading to a new sub. I have a 1,000 Sq Ft living room and need a sub that will really dish out Db's. I had read that the earthquake supernova was rated "one of the loudest subs on earth". I am currently running all passive Def techs in my system so it needs to be a sub that will integrate with my BP's. I read a few advertisements for the DT supercube reference that is supposed to be able to put out the equivalent of three Supercube 1's. I am able to purchase either one for 1,100 $. What is the best deal? I am currently using a Atlantic Tech sub that I am going to daisy-chain with the new sub, so the new subs main job will be 40hz and down. Also in consideration is two SVS 16-46pci's. I heard that two of these sub for approx $1300 will blow you away in both Low end and volume. If you use two though, do you port tune them differently so you get both low end and volume?
