Absorption/Diffusion

Effective absorption to 100Hz.

Diffusion upwards starting at 1,000Hz

Core

Rigid rockwool provides twice the low end absorption over similar foam-based products.

Design

Thin face plate has mathematical sequence of slots for spatial diffusion, but also allows low frequency waves to pass through to the rockwool panel for low end absorption.

Weight

Square (600mm x 600mm) and Narrow (300mm x 1200mm) = 4.8kgs

Rectangle (600mm x 1200mm) = 9kgs

NRC

1.05 (versus foam products where NRC = 0.4)

Construction

100mm stury wood frame with rigid rockwool core

absorption material.

Quality hand-made construction and craftsmanship

Standard Sizes

Square 600mm x 600mm

Narrow 300mm 1200mm

Rectangle 600mm x 1200mm

Suggested Placement

The 4A Alpha Panel can be used on the front or back walls and rear sidewalls to keep the reverberation better mixed and the room lively.

It can be utilized on the rear sidewalls or behind dipole speakers to round off sharp reflections.

Anywhere in a tracking room or other large spaces, helping spread out the energy evenly across the whole room.

Add freestanding supports on rectangular (600mm x 1200mm) Alpha Panel and position the Alpha plate outward for diffusion or turn the fabric side outward for broadband absorption. Also allows for flexible placement in early reflection points or straddling corners as a bass trap.
