hi guys, Thanks for your feedback... I added a reply, but I see it got removed for having an external link :/
regarding dimensions: the height and depth were determined by the cabinet it will be placed under (70cm high, 75cm deep)
I was a bit flexible with the width, I used 52cm, based on a ~9cu ft net volume.
I had the bracing planned and drawn, but decided not to add it yet
The wood i am using is VERY heavy and VERY hard. It does not flex/vibrate.
I use several types of hardwood, most are called "basralocus".
This wood had a VERY high tensile strength.
I know about cabinet bracing, and I know what purpose it serves.
IF at a later point I do need bracing, this can be added, as the baffle and the top of the enclosure will be screwed to the frame.
What would be the benefit of using an internal box made out of mdf or plywood ?
