ORIS 150 Back Chamber (BD-Design)

Hi Mart,

Increasing the size of the back chamber reduces the Q of the system giving less output around 200Hz (less body). This effect can basically be heard when you remove the wooden back cover (leaving the circle felt in place).

Adding damping material is doing the same more gradual but also takes away liveness.

Just play with it and listen to the changes. Some prefer to have removed the wooden plate and all the woolfelt and then stuffed loosely with "hairy" damping material.

Ciao,

Bert
