    @123toid Hope everything is ok at home now Nick (wellness wise).

    As for the speakers, they look great, loving the build quality and the colour too (even if it’s not really for my decor 😂)! I’d worry a bit about port turbulences though, there doesn’t appear to be a flair (unless I missed it, images are quite contrasty), there’s actually a lot of really interesting engineering as to why flairs are so important, even if just small. It’s to do with how the boundary changes between the enclosed space of the port and the comparatively infinite space it opens into, also known as a part of the boundary layer effect. I won’t go far into it (unless people ask of course), but I thought it worth mentioning.

    I know with this speaker, the lack of flare is probably needed since there’s no more room on the baffle for conventional ports, and you’d mentioned previously how it’s not really necessary when crossed over high enough to a subwoofer. However, I’d be more than happy to model up some ports that make better use of space on the baffle so the port area can remain the same whilst allowing for a flare. I’ve done this with 3d printing with great success in the past, just let me know, it might be a nice upgrade in the future or maybe for a V10.5?

    Loving the cinema series style! Keep it up!
