description: Hey dude, Sorry for the constant blabbering every day with questions, but what can I say... You don't learn if you don't ask... It occured to me yesterday that the 'cup' behind the compression diaphram on the PSD 2002's is a highly reflective surface and might be hurting the quality of the sound. I was thinking of putting a bit of polyfill in there or even cutting the back off of my compression drivers and adding on a lined and stuffed termination chamber to obsorbe the back wave. However I figured this chamber is important for the operation of the driver. What do you think? Adam

Rear chamber of compression horns
type: item
description: The back chamber volume is a property similar to the cabinet volume of a sealed box speaker. Its volume combines with the mechanical compliance of the diaphragm surround. This sets the resonant frequency of the motor/diaphragm system, which, in turn, interacts with other horn properties.
