Uniform reverberent field
…very good coverage and also makes the reverberent field uniform throughout the entire audio spectrum, something that is nearly impossible with other loudspeaker designs. Early reflections are reduced while at the same time providing complete coverage and…

Directivity, the reverberent field and "imaging"
On a similar note, we touched on these topics in the thread called "Favorite Flavors."

Re: Differences between "normal" of "horn"-type active filter.
…(such as a treated room), then the reverberent field is of reduced energy. The reverberent field is formed by reflected energies, so in an anechoic environment, there is less energy in the reverberent field. In such an environment, off-axis response has…

Uniform directivity
… coverage angle. The net effect is that the reverberent field is uniform.But if you're used to the sound of a typical direct radiator that falls off off-axis, then having a uniform reverberent field can sound fuller. There is definitely a difference. …

Re: Single sub bad - multi subs good
…sound field average in what's called the reverberent field. The approximate frequency where sound begins to act as a reverberent field is called the Schroeder frequency. Above this frequency, reflections are like ripples from rain drops, so dense that …

Re: Learned some more audio truth outdoors
…m.A loudspeaker's directivity determines the reverberent field. Uniform directivity along with uniform response makes a uniformly charged reverberent field. If directivity fluxuates up and down, then the reverberent field won't be uniform even if on-…

Multisub explained
…a room, the entire audio range creates a reverberent field instead of having a modal region in the bass. That's why very large rooms can be setup sort of like you would outdoors, at least in the bass. But indoors in any room smaller than a few thousand …

Room gain, pressure region, modal region and reverberent region
…and 150-200Hz. The third region is the reverberent range, above about 200Hz.
The pressure mode is at low frequencies with wavelengths longer than any dimension of the room. This causes a uniform bass boost of approximately 12dB/octave. Boost is …

Re: Corner Horn positioning "Sweet Spot" for listening...HELP
…of the π cornerhorn configuration. The reverberent field is very uniform because off-axis response is the same as on-axis response. The best listening places are those where the listener is equidistant from the speakers and where the angle between …

Pi horn design philosophies
…was so special was to provide a uniform reverberent field.
Getting a uniform reverberent field requires having flat power respsonse. The total sound output on all axis be equal in amplitude. It doesn't have to be omnidirectional, in fact, it is better …
