Fitting drivers in cylinders pros & cons

[56oval]

Hi DIY

Is there any hidden problems fitting drivers in cylinders .
This is just a rough sketchup I was thing of using a clear acrylic
frame to support the tubes .

The cylinder cabs will be made of steel or alloy which I know how to work with .
Heres the original cab I was going to build


Cheers

Hi Khron

I have a copy of Olson's AES paper and I can't find what size driver he used and I think it wasn't that large and the cylinder
had an end plate 24" just under 610mm wide with a small driver in the middle would the test out come be the same if the driver's diameter is as close to the edge as possible .

Hmmm might have to make a clear acrylic front baffle .

Thanks for the reply

Sure, although when the driver is large compared to the baffle it becomes directional and lessens the diffraction problem.

Compare and contrast Siegfried Linwkitz' measurements of a 25mm tweeter naked (1.5" baflfe) and on a 3" circular baffle with the Pluto (1.6" tweeter, ~2" baffle). 6 and 12'" measurements are also provided for the 1" dome.

The Pluto is getting directional before it's an issue.

I suppose the ribbon tweeter will force a high cross-over point, although a small enough mid-range would keep that from being a problem.
