I have an Xtant 600watt mono amp. I am looking for the loudest deepest 12" subwoofer I can run with that amp. I have narrowed it down to 2 choices, either an RF HX2 500/rms 1000/max or a pioneer TS-W2000SPL 750/rms 2,000/max. I am kind of leaning toward the pioneer, however I cant find out much about it. none of my local stores have one on demo. Do you guys think my xtant amp will be able to run the pioneer? is the pioneer a good sub or would I be better with the HX2? I realize that most of these questions are up to personal opinion, I am just trying to get some feedback. Thanks in advance for your help.
