Quote:Where this variation of the ultraflex differs is in the cut rear corners and of course the 8 degree angle that the entire cabinet is raked back at. These two things eliminate most of the parallel surfaces inside the box.
As far as I can see the front and back is perfectly parallel?!
Yes, the back plane is smaller than the front but the driver will still get a lot of reflections from the back. Right?
A NERF ball or wool behind the driver might reduce the reflections. Or better - no back plane at all.
Quote:No doubt someone will wonder if they can build it without the 8 degree skew and then just lean the cabinet back 8 degrees after it's finished. This will work but the sound and appearance will be lacking compared to the building it the proper way.
I missed the point here... As far as I can see the parallel top and bottom plate should not cause any major problems as they are handled by the NERF balls.
Yes, the ducts are angled 8 degree but I can't see what it should matter due to the wavelengt coming out of the ducts.
In europe we use Rock-Wool (isolation for houses) and wool to dampen the reflections inside cabinets.
1-2" Rock-Wool on all surfurces and wool in the open space inside the box.
Any thoughts?
