2D diffusers

Diffusers, whose construction diffuse sound waves semicircular, in two ways. Recommended especially to place in the points the first reflections behind speakers, in front of the listener.

Lower frequency range corresponds to the depth of the slot and higher frequency – its width.

Number of slots of the diffuser has an impact on the diffusing factor – the more slots means better.

The terminology in the name of the body

The first symbol before the slash indicates number of so called wells.

The second symbol after the slash indicates the approximate width of the body in centimeters.

Additional word basic means budget version (with a thinner frame made with plywood instead of wooden, with narrow choice of colors).

Example: 19+1/120 basic = 19 +1 wells / width of 122.5 cm, a simplified version
