If it were me I would upscale the bracing into full intelocking shelf braces, especially with the wall thickness you have selected. Is there a reason you are going with a low rigidity cabinet? Do you intend to include extensional damping?
E-A-R Specialty Composites
IME mass+stiffness+damping is the proven way to make an enclosure "quiet".
Constrained layer damping is superior but is precluded by your construction method.

Evening

Bonding the ports together once these are dry I can glue them in and finish the bracing .

Hi Bon
The bracing isn't finished and already with the knuckle rap test you can hear the difference .
