” That logo reveal should almost overpower a room with acoustical energy, but this just wasn’t the case with the 450. While it did produce some output, it seemed to run out of gas in the very deep bass, at least compared with each of my reference subs (playing individually). There was sound, to be sure, but little punch for this kind of low-bass content, and some direct A/B comparisons really highlighted the 450’s limitation in this regard. When the logo slammed on the screen, it did so with a whimper, not a bang. Furthermore, I couldn’t feel the sonic impact of Buzz’s afterburners.
