I'm spoiled. All the sound systems in my apartment are perfect. I am particularly proud of my under-bed sub.
Our garden system sounds good too (an entirely different conversation).
The fun part is that the garden cupboard sits on a pallet.
A UK pallet measures 1200 x 1000 x 130mm - a whopping 120 litres!
Of course I'm thinking SUBWOOFER!!
The 130mm height provides serious challenges but wouldn't it be an engineering coup to design something half decent?

OK, I'm up for some more fun! 😉
How do you envisage dealing with the gaps?

P.S. On checking the arithmetic, I find that (1.2 x 1.0 x 0.13) m = 0.156 m^3 = 156 litres.
That's external. Internally it's between 125 & 130 litres, then I need to deduct for the drivers, bracing & ports.P.S. On checking the arithmetic, I find that (1.2 x 1.0 x 0.13) m = 0.156 m^3 = 156 litres
If I use 6mm MDF top and bottom it's 1200 x 1000 x 142mm.
Yes.Is your pallet a "block design" as shown in this inverted view?
I don't know what that means.You may have modes below 200Hz in the basic configuration.
The distance from the middle to the corner of the pallet and back, is a half wavelength there. You'll have to take this into consideration especially if it affects your cross.

I'm going for a cross of 80hz.
My current plan: (Long-side to front). 6 x 100 x 400mm ports to front elevation. 4 x 5" drivers opposed in the short sides.
If I use 6mm MDF on top and bottom surfaces, internally the surface of the cabinet is ribbed - I've no idea how that effects waves.
Possibly I could use a full length front to back brace, effectively making two cabinets.

The "ribbing" dimensions are small compared to the very long bass wavelengths involved.
I submit that the internal bass waves will be "unaware" of the presence of the ribbing.
