building bass hangers to treat 125Hz and down

[stevelaw]

Hi,
I need to treat/trap some bass energy around 125Hz and down. Ive already got some acoustic foam traps in the corners, but i feel they're a little inadequate. They did a good job of 125-500Hz though. So I think ill build some bass hangers to try and tame this problem area.

Is there a size i should be aiming for.??
I was thinking of making a open box, wider than it is high, have a bunch of hangers in there with rockwool on all the sides and hangers, and cover the opening with some cloth.
Thoughts..??
Cheers.

some 4" absorbers - 2'x4' - would help. per the other thread asking the same question - you could then introduce some diffuser panels (small 2'x2' say) and tweak to bring some HF back up.

hey thanks..
are the 4x2 absorbers for first reflection points or bass trapping..?
what'd you think of the bass hanger idea..??

the broad band trapping using the hangers is workable if you have the space.

Sorry to be a bore, but could you post that link?.......

There are a few recent threat a dealing with absorber sizes and placement and putting things in front recently. But if you do a search on 11x15 room showing corner hanger traps.
