@kevinappel - the room IS NOT your friend. I agree with the suggestions above.
I play bass and recently we played at a hockey arena - concrete and glass everywhere. I had to turn my bass amp way down AND lift the amp onto a table
The down firing port on your speakers, onto concrete floors is the issue - you need to damp/absorb those waves as soon as they leave the enclosure
Try small rugs around 3ft x 5ft under the speakers. The spiked feet should go through the rug to anchor the speakers to the floor.
Also bass is omni directional so putting carpet/rugs in front of the speaker would probably not be as effective as putting the rugs under the speaker.
As others have posted, try to get soft materials onto the walls also - a cheap(ish) material that can be used is carpet underlay - just stick it to the walls.
Hope that helps - Steve
