As for speed. It is also a non-issue with bass. Bass extension and impact was never an issue in my system but the SigTech proved me wrong. What I was hearing before was room reinforced, time delayed, and phase incorrect bass. The SigTech successfully integrated my multiple subwoofers with the Alon V's.
Music takes on a character of great pace and timing.
With a little more fine tuning, the whole sonic picture is presented as an organic whole. Flat as a pristine lake in a perfectly windless night, dare I say, is the overall response. Try if I may, I can not sense any crossover discontinuity or room modes. I am hearing the future and the future is very promising. Just think of SigTech TF1100 as the tip of an iceberg, advent of a new technology.
