A:Answer Thank you for a great question on our D32x-D1!
It would fit within the cabinet opening of 31.5", as it's 28.6" wide. However, the stand legs are 23.35" apart at the furthest, so fitting it on a 23.5" wide shelf would be extremely tight.
If you have any questions or concerns, we encourage you to reach out to our Support team at 877.878.4946. Thanks again and have a great day! -Collin
