[Plywood thickness USA vs Europe]

I just ignored that te 3/4 '' is actually 18 mm, so I will use 18 mm Baltic birch plywood

Interesting article!

Just make sure you keep the internal volume the same as originals and change any differences in dimensions outward versus inward.  Otherwise, you reduce some cabinet volume.  Not a lot, but some.

Yes it is what I will do. Start from the internal dimensions! Thanks

Hello all,

 

I am in the process to rebuild a Cornwall  I pair in the horizontal collector version in mahogany finition. (will be beautiful!)

However US Plywood thickness standard =  3/4'' = 19 mm doesn't correspond exactly to european= either 18 or 22 mm!

What you, Cornwall lovers and klipsch lovers,  would recommend. I think that the cabinet design , type of wood and thickness  has an influence on the quality of the sound. Paul Klipsch

did kow that for sure! . 22mm could be too much?

Thanks!
