I don't think there's much I can add. The bamboo driver in the Song 3 is very similar to the titanium unit I use in the Phil Slims. Both are designed for full-range use above 80 Hz or so. I think they have the same motor, although the magnets are different. And both qualify as the best full-range drivers I've used. But their strength is very smooth response as a midrange driver. They have plenty of power at the low end to maintain a full sound when crossed to a woofer in the 250 - 400 Hz range, and they have no breakup modes anywhere near the upper crossover point of around 3.5 kHz.
