if by partical you mean OSB or oriented strand board like used to sheet a house that isnt what i used
here are some pics of what i used
the box wont be tested until i get back from camping next monday
my dad helped my a lot with it
i used his portable tablesaw to cut the peices
i secured it with trim nails and Liquid Nails Heavy Duty Construction & Remodeling glue
i made sure it was braced and everything and it seems really sturdy
i guess i need to do things wrong see what happens and learn from it
believe me if i had the money for 3/4" mdf thats what my box would be made out of
the thing is i have 1/2 laying around so i mine as well try it and if it doesnt work ill just build a new one out of 3/4
and plus i just spent all the money i had on sub and amp and i have $0.00 for building supplies
well the box is already made
i think there is a little difference in between a 15" sub and a 10" sub
if the box falls apart so be it
ill just build another one
