Product Description
Overview
Achieve an even decay time from low to high frequencies while providing the necessary absorption to flatten the frequency response
Our Alpha Series panels are made with rigid rock mineral wool absorption material wrapped in your choice of fabric, and finished with an attractive plate which has a mathematical sequence of slots for either one-dimensional scattering/diffusion or two-dimensional scattering/diffusion
SPECS
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 x 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 (595mm x 1205mm) 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.
Plates
Pattern
1D option
Uses a mathematical sequence in a column that extends the length of the panel. The vertical slats of the 1D allow sound energy to be scattered in a horizontal plane.
2D options
2D (a) has a pattern of dots and dashes
2D (b) has a pattern of dashes
Uses a sequence of columns and rows with variable spacing that provides horizontal and vertical scattering of sound. Additional £17.50 each for Square panels and £27.50 each for Rectangle panels
