Buy paving stones in 12 x 12 oe larger. They are 2-3 bucks each about 2" thick and can be stacked to height.
what's better than a milk crate? lol
I have a pair of dyi speakers that are 11 in deep and 9in wide and 23 in tall, they weigh around 30lbs a piece. I am needing stands and can't find a large enough base. Also since they are dyi don't have height recommendation. Currently have them sitting on some cheap wood stands sitting on top of milk crates. I know bad idea but was a quick way to raise them. Will good stands make much of a inprovement?
