Guy, its surprising how well the perf rear cone works.Varying the diameter and spacing of the holes you can shape the power curve dramatically.
Along with the main body diameter/length/volume over the rear cone.
Richard - that is a reasonable assumption to make - but the issue is that the duct exit is too big anyways.
Thus adding ears down the side produces the exact effect you are after , but this is almost exactly offset by the now even bigger area duct.
But if one was to fill the roof and or floor and CNC the correct shape and exit area then that would be an entirely different matter.
Wouldnt have a clue how to do that at all now would I.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
