Raise my subwoofers off the ground approximately 12”?


I’m looking for some sort of subwoofer stand to raise my subwoofers off the ground about 12”.

Any ideas for building something or buying?

What is the reason for doing this?  Does it have to be 12" or are you just trying to get them off the floor to keep from passing vibration to another room or something below your room?  If you just need to get them off the floor, consider the Auralex Subdude - https://auralex.com/subdude/
Turnbowm has it right. You do not want to take your sub off the floor. You will just make them less efficient forcing you to raise the volume distorting the amplifier and the driver. Subs also should be up against a wall or in corners again for efficiency reasons and acoustic reasons. You decrease room interaction this way. Subwoofer manufacturers put their subs on the floor for a reason!
Was in Home Depot today and saw some inexpensive but sturdy stands for water heaters. 21 X 21 X 13 inches. Welded steel, $40 ea..
