driver cabinet isolation
Was thinking about how to isolate a mid driver from itís cabinet. Iíve read several threads with ideas like magnet mounting drivers, or screw mounting with silicone and cork between the driver and cabinet.
I was thinking of floating the driver on a cork/silicone or possible cork/green glue gasket, but fastening the driver by tensioning it with a spring or bungie cord to the magnet. The cord would then extend through the rear of the cabinet allowing the driver to be tensioned and held in place. My thinking is the elastic nature of the spring or bungie would dissipate some energy before it makes contact with the rear of the cabinet.
Iíve certainly seen drivers mounted via rods the to rear of the cabinet, but never using something elastic.
Wondering if itís an idea worth building a test cabinet?
That spring would resonate like a piano string. Most complicated and best I believe is to build a box in box with a layer of soft silicone in between. The front baffle hole of the outer enclosure you cutout 1mm or so larger in radius than the mid flange and you use a small flange on the inner enclosure to mount the mid to so it remains alligned on the front baffle. Not that hard to build if you thing but once done, cannot be dismantled. For bass drivers its more complicated as they`re heavy - I want to try engine suspension shock mounts to hold the inner enclosure from the bottom and the rest to be held in allignment by silicone but have no idea if this would work.
I`ll follow this thread with interest :)
Another method will be to build a cabinet, that would not resonate much or not.
This is what Naim did with the Ovator to isolate the BMR from the cabinet.
The BMR is fixed on a cylinder volumina that is floating attached to the cabinet with leaf springs.
Maybe interesting for your task...
