It's great for high-quality home theater. It's powerful, accurate and articulate.

Yes, close, 38Hz actually. And the positions of the driver, port and internal damping material are also optimized to minimize the effects of internal standing waves.

In a cabinet this size, that's very important. It's arguably more important than the Helmholtz frequency; It's at least as important.

It's basically 1.2kHz, but more important is the slopes and phasing that sets the interaction between drivers to center the forward lobe.
