Post Subject: Don't even see a back chamber...Posted by Romy the Cat on: 9/15/2008
Yes, Keith,
it is how they usually do with front-exited drivers where the back chamber not vented. Some would put a texture on the plate of magnet, some put felt dampers. It look like then have some kind of indentation in there I have no idea what it is. I think it is possible to “tune” this back chamber up in the frequency scale by putting under the diaphragms a space-filing cone. I do not think that there is a way to tune the back change down and it would require drilling the drive’s poll. I have to note that is absolutely unpredictable how the driver might behave reacting to the back chamber expansion or damping. The cone looks very hard-suspended, I dealt very few with those types of hard-suspended cones… I think the mid-bass/bass cone will have more outer superstation.
