You're welcome!

Your call........ both are suitable for vented specs drivers. I'm a major league MLTL fan going on 57 yrs now for its bang/buck performance, ease of design/build, while a quadratic taper yields a much more interesting/pleasing visuals with a slightly different sonic signature due to how the driver interacts with its shape.
