RE: Can It Be a Horn If It Doesn't Look Like One?

A room corner isn't a wave guide. When a corner horn like the Aristocrat or Klipschorn is in a corner the room walls act as an extension of the horn. Combined with the 1/8 Pi space loading of a corner the lows are significantly boosted, although any speaker placed in a corner will get 1/8 Pi space loading at low frequencies.

As to the term wave guide it's vastly overused. Technically speaking a wave guide is a horn with a throat that's at least one wavelength in dimension. That being the case it doesn't have the gain that a horn with a throat less than a wavelength in dimension has. We never saw the term 'wave guide' used until roughly 20 years ago. Someone started using it interchangeably with and in favor of 'horn', not for technical reasons but for marketing reasons, to overcome consumer resistance of the unwarranted poor reputation of high frequency horns. IME at least 90% of what are called wave guides are actually horns. If it's got a one inch throat it's a horn below 13.5 kHz.
