For a box that size, it shouldn't be too heavy. I was used to having 5 cu. ft. enclosure..that with a 75 lb sub makes it very difficult for 1 person to pull out and put into a vehicle. I hope I didnt make it seem like MDF is extremely heavy. The other two are just lighter, though I'd say over 90% of people use MDF for their enclosure, when using wood that is.

 

I'm a 5'11 140lb guy prety skinny, and i can carry this by myself with two subs in it. let me know
