Hi
I've meassured my room i have nulling between 80hz that has an -12dB loss from 70hz.
I what do DIY and floor to backwall bass "corner" trap.
And I need u guys expertice what meassurment the trap should have and design.
My backwall and roof is solid concret.
The room is front wall widt 3.21meter (plasterwall), backwall /rearwall width 2.62m(concret) room length 3.21m and Hight 2.38 m. Both floor and celling is concret.
Thanks for all help

Can you upload images of the room, or link to them?
Also, what is the room used for?
What type of system do you have in the space?
Also, consider this information as it is very useful:
Lay out your system and furniture as symmetrically as possible, ensuring that the left-hand half of the room is as close to a mirror image as possible to the right-hand side. Your system should be oriented so that the side of the room that allows for the most symmetry possible (room shape, speaker/acoustic treatment placement, furniture) falls in front of the listener.
Try to place the listener at 40% of the room depth from the front wall. Example: If your room is 14’ (168”) deep, place your listening position 65” away from the front wall.
Avoid placing the listener or the speakers at the following locations:
Against the wall
At 50% or 25% of the room depth away from the wall in front of the listener
To smooth out low frequencies, install thick corner-mounted treatments. Add one pair of vertically stacked corner panels of 4” thickness in each of the four room corners. If vertical corners are not available, use any available horizontal corners (ceiling-wall or floor-wall). If you are unable to install eight 4” panels, use thicker 6” panels or dual panel arrays in the corners you do have available.
Use broadband absorbers for all acoustic panels so that they work on all frequencies (i.e. lows, mids, highs) evenly.
Treat “early reflection points” with additional broadband absorbers of at least 4” thickness. A typical application will use eight reflection point panels – at least one pair of panels on the front wall, at least one panel each on the side and rear walls, and at least three panels on the ceiling. Keep all panels below ear level by using short 28”/70cm racks.
Stop and sample the results. Add more treatments only if the room creates too many echoes. In this case, add broadband panels incrementally, two or three at a time, as symmetrically and evenly spread on walls and ceiling as possible.
