^^^ Did you look at the chart for the FV15HP? In single port mode it only pegged a 10.8% THD at 12.5hz and at 16hz 8.77%. Yes, it jumps up from there, but has anyone who has owned a Rythmik ever complained about distortion? I know all I get from mine is crisp clean punishing LFE. I don't care what charts say I care what my ears tell me. Do I think the Ultra is a great subwoofer? Of course, but do I think it's worth the hefty difference in price for lower THD that most people probably wouldn't even perceive? Nope. I do agree with you and the others on the advantages of multiple subwoofers. Also, the shipping is not free for SVS and PSA it's built into the cost.
