Reading the reviews of the T100, one of the knocks on the system was the sub not hitting the lower frequencies and lacking a bit of power. The system up from it comes with an upgraded sub. Looking strictly at specs, the Pinnacle has a larger cone and a bit more power. In theory, that should be an improvement over the KEF. But, specs don't mean squat. I'd rather a clean 8 than a muddy 12, and that might be the case here. Can't tell without listening. That's why I'm here, hoping somebody can give me an educated opinion.
