Concrete speaker cabinets
Hi All,
This is my first foray into speaker building and I think I picked a bit of a tough one. After three iterations I finally got a decent result.
I order the seas drivers and crossover gear from madisound in the states:

Constructed the internal mould for the speaker cabinet using styrofoam, just to make it easy to gouge it out at the end I wrapped the main piece in clingfilm:

missing from this pic is the internal piece for the connection terminal
Then I shoved the port tube in the back of the big piece of styrofoam and assembled the mould:

After a couple of days of drying I pulled it out:

and after a bit of sanding, painting and crossover assembly, I put the whole thing together:

I still have to build a set of stands for them, which will have to be pretty strong as the speakers weigh about 45-50 kilos a pop, as well as that I have to give them another coat of paint and put the crossover into a protective box.
As regards the sound, will know a heck of a lot better when I manage to put them on proper stands and position them correctly, but other than those obvious problems of context, they sound fantastic.
I had the idea of sticking a set of casters on the bottom of the stands that I build, any opinions on whether that would be a good idea or not?
Thanks,
Nathan
