Design consideration, order of importance

[AllenB]

Doesn't that have passive dipole elements? Regardless, I know what you mean, there are others with a philosophy like that..

But what's fine for the speaker may or may not help with the room. If that weren't important, if the speakers were for outdoor use then just ease the diffraction, the dispersion doesn't matter (except where it would help power handling).

Two important issues that may (potentially) betray imaging, giving audible cues to the presence of a baffle system by having time delays and directional and frequency response variations, reflections and diffraction, are connected in design in regards to how the baffle travels and therefore give clear direction to the needs of the cabinet.

There's less rearward reflections making them more wall friendly,

When the speaker cabinet and the first half of the room are not contributing to the sound but the rear wall is, it can be like listening to headphones except that the image is in front of you and solid, it has width and depth, and height cues, you feel the bass, spaciousness can be added in a neutral way, and your ears don't sweat 😀.

"spaciousness"

Maybe omnidirectional should be mentioned, as a concept, although details are less straightforward I think it makes a point about how to do it. Broadly speaking, I think geometrically a room should be an all or nothing thing, except where directional distinctions need to be prioritised, and except with regards to frequency or timing.

"Time alignment" is such a misused term. As Bill says, aligning the acoustic sources is mostly useless until you consider the effect of the crossover. Remember, the phase through the crossover region is all that matters.

True, and it only matters if a LR crossover is used, a time alignment allows for true symmetrical LR crossover to be used with its benefits on the vertical plane. If that`s not the plan, it would be unnecessary carpentry work.

If the baffle is narrow enough, the edge diffraction frequency would be upper in the band reducing the need for chamfering and the way it is perceived by the brain.

I am using 2nd order LR.

AllenB,

I believe you. I've heard Live-End, Dead-End like installations and that's pretty much what they sound like. Personally I prefer a more balanced approach focusing on initial arrival reflections and diffusion behind the speakers.
