Interfering
reflections from a critical listening room’s boundary surfaces corrupt
the timbre and stereo imaging. Therefore, signal processing and image
placement will not transfer accurately to other listening environments.
The most effective way to minimize this form of acoustic distortion is
to absorb the interfering reflections over a broad range of frequencies.
To extend the low frequency absorption efficiency of conventional flat
absorptive panels, RPG® research developed the Abflector™. The
Abflector™ is a novel and economical internally hinged, upholstered
absorptive panel. It ships flat, but mounts with most of the absorptive
material away from the boundary surface for improved low frequency absorption.
Problem
Small rooms like Project Studios need a very efficient surface to absorb
first order reflections over a broad range of frequencies. This is not
possible with thin, flat, surface mounted porous fiberglass or foam panels.
Solution
RPG®’s internally hinged Abflector™ ships flat for economy,
but installs as a splayed wedge with a Variable Depth Air Cavity. This
unique mounting improves bass response, increases the angle of incidence
and deflects high frequencies.
Performance
 The
Abflector™ offers a Variable Depth Air Cavity (VDAC™) to improve
bass absorption. The Abflector™ simulates the beneficial Reflection
Free Zone™ effect, created by outwardly splaying side walls in a
rectangular room. The graph illustrates how the Abflector’s™
innovative hinged panel mounting exploits the advantages of the air cavity.
Notice the significant increase in the low frequency absorption over that
of a similar 1" thick flat panel, mounted directly to a boundary surface.
Installation
The Abflector™ is easy to install with its
attached hook and loop fasteners. Hardwood feet are also available
for floor standing installation.

& Benefits |
Features
Internal hinge
VDAC™ mounting
Simultaneously offers diffusion and moderate mid-band absorption
Aesthetic splay design
Benefits
The unique internal hinge allows the Abflector™ to be mounted
with a Variable Depth Air Cavity (VDAC™). This method eliminates
the expense of field installed spacing systems for flat panels
The internal hinge also allows the Abflector™ to be efficiently
packaged and shipped flat to reduce shipping costs
The different length panel segments form a visually interesting
architectural splay, which adds elegance to the look of simple
rectangular rooms
The Abflector™ forms a splayed side wall surface, which
increases the effective panel thickness and also deflects interfering
reflected sound away from the sweet spot
A wide range of fabric choices also complements the unique splay
design
The lightweight panels can be applied to walls, ceiling, or
used as a floor standing panel |
