Good idea;
but if it is not for production so no need for shipment you may afford concrete boxes; they would sound much better than wood: no problems with surface resonances (stiffness) and reactive oscillations (mass).

Here you may see the secret how I make woofers:

Monitors with good bass is the mast: recently I've bought a CD of Josh Groban, but can't listen it without EQ: some kick drum sounds on frequencies below 40 Hz too loud (my home Hifi is flat from 16 Hz to at least 24 KHz). Most probably mastering engineer used nice stock Yamaha monitors or something similar so could not hear that drum properly...
