Low Frequency Envelopment in Listening Rooms

This talk explains why we need not suffer the flat, lifeless bass sound that results from a single subwoofer, or a single subwoofer output on a receiver. Contrary to current practice we put two or more low-frequency drivers where they avoid exciting strong medial modes while emphasizing medial modes. If all else fails, a pair of stereo at the sides of the listeners can be very effective. Tracks for a test CD for low frequency spatiality can be found at this dropbox link: https://www.dropbox.com/sh/0xxrfcseee... There are also a few musical examples. I will get a link on my web-site soon. on the author's web-site.
