Here are some pics of my recent X1 build using the Void V18-1000 and heavy duty rubber feet on the bottom. It's powered (along with the two MHB-4818s) by a 4-channel CVR 2004 (2,000W per channel at 8ohms). Combines well with the kicks to give the full bass spectrum. I haven't used it live yet but in tests at home (in my tiny sunroom) it sounds insane. Tops are MT-121s of course (powered by CVR 1004).

Feel free to ask questions about the build! it's fairly straightforward and took me around 2 days for the main enclosure (plus another few weeks on and off for all the other fittings, etc).

You forgot to make an access panel?

I don't love access hatches so I leave one side un-glued (but use plenty of screws) so that I can replace the driver if needed, but also so I can fix any internal issues that may arise.

That is a very strange way to make speakers. But Hei... What ever floats your boat 🙂

how does the overlapping band play with the mth4818's? Does the 50-80hz or whatever sum clearly and have a good tone no weird reverberations from group delay or phase differences? Or do you have them clearly cross'ed over (x1 30-60 and 4818 60-120 or something) Do you wish you'd just built out all the same cab?

Anyway look very nice and sturdy no flexing probably sounds great.
