I'm looking for new subs and I am currently demoing the svs ultra sb16, but its leaving me disappointed. I was also looking at the rythmik f18 or the 15, or even the monoprice subs, but heard mixed reviews on quality of production of the monolith subs. Any other recommendation, preferably sealed as I hate port chuffing and don't want to deal with that if I push the subs to hard, and under 2000 per sub. And I dont know about hsu, I'm just too used to my 1700watt sub to go down in wattage, due to my bad experience with a klipsch 12 that was 250 watt rms then going to the paradigm studio sub 12 with 1700 watts was just night and day. I want something that would produce low end like edge of tomorrow opening or the black hawk down helicopter scene where you can feel the room rumbling, which the paradigm can do, but it isn't so good with the higher frequency bass notes, due to a bad room null from 50-70hz. Wish I went dual before the paradigm stopped selling that sub otherwise I would have been set.:rolleyes: But starting at square one.
