I have just ordered an Orbit Shifter for my dad's media room. It will be replacing his Epik Conquest/MBM-12 combo.
I will have plenty to report when it's all setup as I'm making a bunch of changes at the same time (moving from Jamo D7s to JTR T8s and Slanted 8s). I've owned plenty of subs myself (SVS PB2+, JL F113, Hsu ULS-15, currently have a Submersive). Excited to join the OS club and add one more of these awesome subs to California.
By the way, for anyone trying to get a hold of Jeff, as has been stated before, just give him a call. He answered the very first time I tried him this morning and we exchanged numerous calls after that while I was deciding on what to order. He was very helpful and I think we reached the right decision in the end.
I was debating between a powered Captivator, Growler Duo, or Orbit Shifter. Room is 13x21x9 with a completely open back wall to the rest of the house.
