So, help me out a bit here. Since bass is perceived as omnidirectional, I'm having a difficult time getting around the "reflected" portion of your response; reflection usually indicates directionality. And while I understand that we're dealing with multiple harmonics of the actual fundamental (induced by the room modes), how is it that, for example, a 60Hz fundamental with a wavelength of nearly 19 feet can be "reflected" by anything (rigid or not) until the fundamental's period is complete? Or, are we merely speaking of reflections of much higher-order harmonic multiples of any given bass frequency?
In my old listening room, which was in the basement, one could perceive standing waves of the fundamental bass frequencies outside the actual room boundaries - the room itself was situated at one end of a 50' x 26' cellar. It made for interesting acoustical studies!
Thanks.
