Open back cab for TA-15

[tm108]

Hi, I'm looking for open back 1x12 cab for my new TA-15 and can't decide if i'l get the Transatlantic 23 or the compact open back. Is there much sound difference between those because of the size difference or do I just have to decide on the looks? Transatlantic cab would looks nice with the amp but I already have 1x12 Thiele cab and since they look the same they might look better when stacked

Thanks
