Last part of construction on the new room for ToKwerX; the rear wall bass trap. Leaving a cavity of approx. 40 cm between the rear wall panels and the diffusion wall this should essentially kill frequencies from approx. 190Hz down disallowing them to re-enter the room. The diffusion wall is also packed with Tontines 'Sound Blanket' specially rated for low end frequencies. Whilst the room already sounds incredibly flat this rear wall will allow SPL levels to be increased without the low end resonating within the listening space. My catch-cry for the new space has become "it will only get better and better."
