Could anyone tell me if this design will work? I'm very new to speaker design so haven't fully grasped how flared ports affect things... I've seen a similar design on the build guide section of this website but with just the front port flared. Many thanks!

Your link seems to be demanding I sign in to google, which isn't great.

Please could you post the image on ImgBB, Imgur etc and post the link here so we can all see it?

It looks like a letterbox version of the K bin which Rog designed. 
Any idea of advantages of a flared port?

It does look very similar actually! The flared ports are for aesthetic reasons in my case but I'm also looking for something that would play around 35-80hz. This is why I based it on the letterbox X1 design but I'm just starting to realise how precise these things are. The K bin is tuned quite a lot higher than I need but looks incredibly similar to my eyes. I've got a lot to learn!

This might be getting towards a post for another thread, but can anyone tell me a way of working out the tuning frequency of my design? I have WinISD but I'm pretty clueless as to how the chamber and port volume in that relates to the actual dimensions of my model.
