I would add pockets to the sides and back of the cabinet that I would fill with sand.
Those side walls can radiate sound you do not want to hear and you quickly eliminate that.
Taking a cue for Bruce Edgar: place the cabinet in a sand box so the bottom is isolated from the floor.
THEN place the bricks on the top.
When I was using Edgars horns for the EV15 woofers I would do this and it does work very well. I did feel sorry for my floors! Makes moving the speaker impossible. I would use a ship vac to remove the sand.
Now using a round horn I cannot do as much mass loading. Maybe the round horn does not need as much help?
