Interfering reflections can be controlled by absorption or diffusion. In small rooms, it is often desirable to control interfering reflections and provide an ambient sound field using diffusion instead of absorption. When the room’s surfaces are relatively close to the listener, a very efficient diffusing surface is needed. To solve this problem, RPG® patented the Skyline®. It is the industry’s first — and most efficient — omnidirectional primitive root number theory two dimensional diffusor. The Skyline® LP has been designed to offer efficient scattering in situations where available wall depth is limited. In 4” maximum depth the Skyline® LP scatters incident sound uniformly so that the acoustic glare in all directions is minimized. No other diffuser on the market can claim equal performance at this depth.
Problem
Small rooms like Project Studios need a very efficient surface to diffuse interfering rear wall reflections and provide a diffuse sound field. Available wall depth is often limited due to smaller room sizes, equipment locations and other furnishings.
Solution
To solve this problem, RPG® utilized advanced primitive root number theory to design the most powerful and aesthetic two dimensional omnidirectional Low Profile diffusing surface in the acoustical industry.
Absorption

The solid expanded polystyrene core of the Skyline® LP provides useful low frequency absorption.
Installation
The Skyline® LP is very easy to install on walls or ceilings using
the supplied hook and loop fasteners. Apply both sides of the hook
and loop fastener to the rear of the Skyline® LP in each corner on
a flat area. Remove the protective paper from the exposed side and apply
to the wall. For permanent mounting, construction adhesive
must also be applied, where space allows on the back of the unit, along
with the hook and loop fasteners. The Skyline® LP can also
be inserted
into a T-bar ceiling grid.
WARNING:
The Skyline® LP is fabricated from flame- retardant, high- density expanded polystyrene foam. It is the nature of this material to have rough surface imperfections and contain steam vent holes. Some of these imperfections can be partially concealed by a factory paint process. If you are interested in a painted product, RPG® offers a painted version in Duron Multispec Fine Fleck paint. RPG® does not recommend that the Skyline® LP be painted in the field and assumes no responsibility for any damage resulting from field painting.

| Features
& Benefits |
Features
Patented optimized primitive root reflection phase grating in a new low profile configuration.
156 distinct phase blocks
Suppressed specular scattering
Universal mounting design
Portable, lightweight construction
Unique acoustic sculpture
Benefits
The Low Profile configuration allows for application in Project Studios and Home Theaters where available wall depth is limited.
The large prime number design offers the acoustical industry's highest reflection density. This design provides a natural sounding ambiance and the most effective diffusive control of interfering reflections
The specular suppression afforded by the primitive root number theory design means the "mirror" reflection component of the scattering is reduced creating a more diffuse sound field
The lightweight and universal Skyline® LP design with perimeter flange permits mounting on a wall, ceiling, or free standing portable gobo partitions with hook and loop fasteners or in a T-bar suspended ceiling grid
The complex number theory topology allows one to work closer to a wall surface than would normally be the case. Thus, small edit and recording control rooms can be optimized
The Skyline® LP’s unique sculptured topology makes it a welcome aesthetic addition to the decor of the room |
