In terms of exterior design, the most distinctive feature of the Kaiser Acoustic SD is its irregular wave shape, which contrasts with conventional space-tuning materials that tend to have angular or standardised shapes. While angular space tuning materials tend to disperse sound in a specific direction, Kaiser Acoustic SD has a structure that allows infinite (∞) sound dispersion due to its smooth, irregular surface with different heights.

Another relevant feature is its solid and heavy structure. Space tuning materials are devices designed to disperse (absorb) negative energy, which generates natural vibrations. Therefore, it is important to take into account changes in sound due to vibration and resonance of the room tuning material. The Kaiser Acoustic has a hard surface and an interior filled with sound-absorbing material, which minimises its own vibration.

This feature results in a noticeable improvement in sound quality. The ability of the Kaiser Acoustic SD to disperse and dissipate reflected waves at a wide variety of angles instantly improves the soundstage by preventing energetic reflections in a specific direction.

The greatest advantage of Kaiser Acoustic SD is its ability to enhance the soundstage without altering the original tone. Unlike other room tuning materials that can negatively affect the tone, SD1 maintains a natural and balanced tone, providing a broad and transparent soundstage.

Product features (effects):

- Sound dispersion from multiple angles.

- Solid internal structure without vibration.

- Comb filter control effect.

- Sound stage broadening in all directions.

- Unchanging tonal neutrality.

- Clear reproduction of diverse tones.

- Natural reverberation throughout the entire range.

- Quiet stage ambience.

- Comfortable view of the stage.

- Alleviation of echo and flutter phenomena.

Placement:

For the Spline Diffuser 2, it is recommended to place the speaker on the rear wall first. This arrangement allows the SD2 to blend naturally into the space, creating a deeper and wider soundstage by eliminating energy reflections in a specific direction.
