In a double blind test 2 out of 3 people liked the sampson over the gemstone. The only one who picked the gemstone was my wife and she has really good hearing. It was hard for me to tell, I can tell a difference but it is hard to describe the difference and whether it was bad or good. Just different(slight). I also had to turn down the pro amp 10 db's to level match. Now this pro amp is not cheAp and your crown is even more expensive. I did not like the cheaper crown's as much. I did buy mine used and for that price probably one of the best amps for the money I have ever heard. Now back to the subs.
I have 2 18 inch horn subs located in the back corners of my theater. They measure 35 x 35 x 22 and weigh about 160 pound each. Having 1 in 2 corners really helps the extension and I can not localize them at all. It actually feels like it comes from the front sometimes. They are not eq'd but I am looking in to this. I just split the sub channel on my processor and then run it to my sampson, then to the subs. I gain 5 db's with them in separate corners compared to colocating them, this smooths out the bass in my room much better. Any seat in the theater now is within 1 db of each other. I used to be 3-5 db's off from front row to back row using just one svs plus/2 sub. If I corner loaded the SVS it would be 6 db's off from the back row and front row.
BTW I always thought proceed with B&W was a great combo, and the cinenova was much better than Krell kav stuff, never heard their FPB gear.
