Any way, My install is complete. OMG. This is just a crazy good sub. But it is not just the sub. Mark did a complete system overhaul for me. The results were quite dramatic. The sub has +-4db reading down to 8hz in my room
. Dynamics are just insane. We played clips of Master and Commander, U-571, and Open Range
. I will put it to you this way. Instead of just watching a gun fight, the dynamics are so good that it sounds what guns would really sound like. The thunder sounds like real thunder. Not just movie thunder playing loud. It is quite impressive. I have no regrets about this at all. Just as a reference point, my previous sub was ported, had a 13.18in driver and had a 400watt amp. It started to drop off hard in the mid 20's at least. This is a completely different animal.
Not to mention that Mark is a great guy to meet and he is wicked smart. When he was testing and using his lap top, I was in awe. He would change the crossover a bit. Or the speaker distance in the processor or the delay times just a bit. But the results were dramatic. My theater has never sounded like this. It was a total system upgrade.
Mark has got fairly uniform results in all installs. It will have a roll off down to 10Hz in most rooms. Output is major in all respects. Although Mark will tell you there is always room for more. I am very happy. Anybody looking for a new sub HAS to consider this. You will not be sorry. I am not. Look for more views when I am able to watch some movies when I get back from vacation. Mark said that he would post some charts from my room next week.
