I love the 20-39 PC+, but it took some time, placement and settings, I was running it turned to 12 o'clock, and it was too much, I am one setting below that, with a corner placement and crossed at 70 on the Yamaha receiver. It's hard to imangine a much better sub. What is HSU's future "offering"????????
