Re-design stage monitor after a big failure.

Hello everybody, as someone read before, I tried to repair my broken stage monitor, but with no success.

So, the thing I want to do is to re-design a new active stage monitor, from scratch (or copying some projects here and there LOL).

Now I have a blank wood edge monitor, even with no holes. I have the transformer, and I have to buy the rest.

Can you please help me in construct something good to use in live?

second, I have two wood case, I could even create a passive monitor to use with an amplifier, but I don't know what component to use or if is cheaper to create one by myself than buying one.

Waiting for your answers.
