The purple Halo Reflection Filter from Aston Microphones is made with patented PET-felt acoustic technology and molding techniques to reflect, absorb and diffuse sound in both professional- and home-studio environments. Its large surface area provides linear absorption, while the corrugated surface diffuses sound for minimal coloration.

The Halo's spherical shape yields horizontal as well as vertical filtering, while its 4-inch radius improves sound isolation, making it a practical solution for recording vocal tracks or multiple acoustic instruments in one room.

You can experiment with placing the Halo in different room locations depending on the desired reflection and absorption characteristics. It is portable and lightweight and comes with proprietary mounting hardware.
