I'm glad I have been taking my time with this. It's been an excellent journey so far. Getting to hear the SVS subs was a great find especially seeing what a change in the settings makes. They had both the 4000 and 16 ultras and I like the 4000's better with the way they were configured and they definitely seem to have enough punch for my space with running dual. I will find out for sure once they are delivered and I get everything setup. Since I am doing some flooring work this weekend they won't be delivered for another 2 weeks or so but I am patient lol. Put out a call to a couple more boutique shops to see if they have anything to audition and waiting for a call back now.\n\nWell I think you did great for sub choice (and AVR, tho the 4500 posted above would easily equal it). I think a pair of 4000s wouldn't make me miss my MK5s at all. In fact I wanted SVS, but my budget just didn't have the room.
