Funderade lite över lutningen bakåt.. är det nån annan tanke bakom detta än få elementen i fas?
Eller är det för att få bättre energispridning(mer takreflex) eller nåt?

Carlsson Ortho-Acoustic Loudspeakers are designed to make the sound that is reflected off the boundary surfaces of the listening room enhance the quality of reproduction instead of degrading it.
An Introduction to Carlsson Ortho-Acoustic Loudspeakers
Consider a quite normal living room - four walls, a floor, a ceiling. and soft as well as hard furnishings - which has the usual combination of reflecting and absorbing surfaces that gives a pleasant sound to live voices and instruments.
Imagine a loudspeaker which is wall-mounted or floor-standing near a wall. Any loudspeaker has its transient and frequency responses modified by the sound reflected off the wall and the floor. This usually boosts the low bass but causes interferences in the upper bass and in the midrange, resulting in a loss of bass and midrange definition. Imagine the loudspeaker being designed to avoid interferences due to reflected sound from the wall. And imagine this loudspeaker
being carefully designed to make the direct sound from the combination of loudspeaker and wall have virtually accurate transient response and virtually flat frequency response.
After the arrival of the direct sound, the listener receives a great number of reflected sound waves from the room boundaries. With a loudspeaker of normal type, the spectral balance of the reflected sound differs from that of the direct sound because most of the reflected sound originates from directions in which the loudspeaker has an inferior frequency response, with a darker tonal balance. Imagine the directivity patterns of the drive units being arranged in such away that the reflected sound from the room boundaries will have substantially the same spectral balance as the direct sound from the loudspeaker/wall combination. The loudspeaker can now reproduce the body, openness, and airiness of live sounds.
With conventional loudspeakers. musical as well as stereophonic
information is often focused to a very restricted listening area equidistant from the two loudspeakers. Imagine the directivity patterns and orientations of the drive units being arranged to allow the listener to enjoy a musically informative stereophonic reproduction throughout a large part of the listening room.
Carlsson Ortho-Acoustic Loudspeakers are engineered to allow the listener to take full advantage of the intrinsic acoustic merits of the domestic listening room. Within their pioneering shape they have the means to govern, in different ways, the quality of the sound reflected off a nearby wall behind each loudspeaker as well as the quality of the sound that will be reflected off the remaining walls and the ceiling. The Achievement is best described in two parts:
1. Carlsson Ortho Acoustic Loudspeakers are designed to operate with their backs close to a wall. In this position they neutralize the acoustic effects of the wall. The wall virtually disappears and opens the listening room into the recording venue, creating the impression of an extended acoustic space. (The acoustic technique for neutralizing the effects of the wall is given a separate presentation.)
2. Characteristic differences between direct and reflected sound are avoided. The direct sound from the combination of loudspeaker and wall has a virtually flat frequency response, and so has the sound reflected by the listening room. This is achieved
by means of a unique sloping panel on which carefully selected drive units are mounted to face a point well above the central listening area, and above the llstener'sears.
The result is clear, solid reproduction of each individual instrument within the spatial topology of the recording. The sound is liberated from 'room' colourations and other clues that remind you of loudspeakers and listening room rather than of the true sound of a live performance in a suitable environment.
