Demi Evolution PolyFusor Diffusor / Absorber
The GIK Acoustics Evolution PolyFusor© is a combination of a polycylindrical sound diffuser and an absorber merged into a single unit. Polycylindrical diffusors, polyfusors, or also known as poly acoustic diffusers are well-known for their excellent dispersion characteristics over a very wide range. The curved front plate of the Evolution PolyFusor© allows for virtually perfect spatial diffusion, while simultaneously allowing lower frequency waves to pass through to the cavity of absorption behind.
Packaged in pairs. At half the size of the original Evolution Polyfusor, the advantage of the Demi Polyfusors is their ability to be put up at alternating orientation.
Price is per box of two panels and includes GST!
The Evolution PolyFusor© provides a great mix of absorption and audio diffusion capabilities. Polyfusors offer a wider band of spatial diffusion than a typical quadratic residue diffuser, but do not affect the phase of the incident sound. Thus the Evolution PolyFusor© is best suited to spreading mid and high frequencies out in a room.

A strong base frame and thin curved front plate which is filled with rigid rock mineral wool absorption material:
Thin wood front plate
White, black, or Blonde wood end caps
600mm x 600mm
WEIGHT 4.5kgs NRC 1.05 (versus foam products where NRC = 0.4) USAGE
he Evolution PolyFusor © is a diffusor absorber as it smoothly transitions as a bass trap from 80Hz, to upper-bass/lower-mid scattering device, to diffusor. Starts diffusing at 600Hz.
Thin wood poly diffuser lets low frequency waves in for low end absorption

OPTIONAL BUILD IN DIFFUSION
The optional Scatter Plate adds built-in scattering to your panels.
Broadband treatments offer great performance with an attractive price and when coupled with diffusion and scattering, can give your room a completely balanced sound throughout, without over-dampening high frequencies.
Price is Rs. 5,500 per plate/panel, and can be ordered as a seperate product.
The GIK Acoustics built-in Scatter Plate option allows even decay time from low to high frequencies while providing the necessary space for absorption to flatten the frequency response.
GIK Acoustics is proud to offer the built-in Scatter Plate option – a wooden plate crafted with a mathematical sequence of slots that adds one-dimensional scattering / diffusion. The Scatter Plate is built-in between the fabric and the absorption material on GIK’s 242 Acoustic Panel, 244 Bass Trap, Monster Bass Trap, Tri-Trap or ArtPanel. Scatter Plates weigh 3.5kg each.
The concept of the Scatter Plate follows that of professionally designed control rooms and tracking rooms which utilize wooden slats along the walls in front of broadband absorption to give an even balance of absorption, diffusion, and scattering. Scattering high frequencies with the use of wood slats, in a mathematical sequence allows you to achieve an even decay time from low to high frequencies, while providing you the necessary space for absorption to flatten the frequency response.
GIK Acoustics’ broadband bass traps and acoustic panels offer great performance with an attractive price, and when coupled with diffusion and scattering can give your room a completely balanced sound without over-dampening high frequencies. The GIK Acoustics Scatter Plate sequence prevents periodicity, while giving great scattering from 2.5 kHz up to and above 10 kHz.
