I've always thought that subs in ported enclosures have a tendency to be boomy and less accurate than sealed subs but I've never heard a ported sub controlled via the SMS-1. IMO for the $ I think one would be better off with a sealed sub with a good eq/amp vs. the cost of a quality ported sub, + an SMS-1 and the extra cables you would need.

I'd love to hear comparisons b/w the SVS SB 12+ vs the ECS-10. Both are very close in price & size. The amp on the ECS-10 looks like the one used in the Velodyne SPL Series. Nothing wrong with that just an observation. JD
