Well I've finally gotten the icing to my HT cake - it's called the SPL-1200. Boy does this thing do what I want and then some. Tight/Deep/Rock-my-world bass!! My old AR PS12 (a 12" slot ported down firing sub with a 150 watt amp) can't touch this thing - nor should it for the price. What an improvement a REAL sub can make. The Patriot DVD's battle scenes have cannon fire that rips right thru me. What a blast. U571's depth charge scene is awesome and the scene where they first take over the sub has machine gun fire that sounds incredible. Each bullet had its own punch. For music, it does even better than I expected. My B&W DM604S2's really shine now. For $875 fresh out of the box, this is one serious contender. This ear to ear grin is starting to hurt !
