More Data

A follow up on my last post.  More data just in from the bleeding-edge trenches of audio engineering! These from my fellow researcher G.M. showing the cumulative spectral decay (waterfall) plots of normal and hypercube-enclosed drivers.

You can see that in a sealed box there is a lot of ringing across the lower part of the spectrum muddying the sound and coloring the notes.

As you can see, the box ringing is almost all gone.

As you can see, the hypercube (green line) is always less than the ordinary sealed box (purple line) — usually by 3 to 6 dB.
