Front wall of my room (behind the speakers) contains the window, so I had to resolve treatment of this room part by stand alone solutions. I decide to make acoustic panels from acoustic absortive panel, put it to the wooden frame and stand it up on the simple legs made by few wooden laths. On the front and back side to cover the acoustic material by breathable fabric (pinned on the light wooden frame). Since panels are relatively thick enough and also situated about 30 cm from the front wall, they are able to absorb also part of low frequencies range. Contribute to better room acoustic response (less distortion) on the bass sounds so it also function of bass trap.

DIY stand alone acoustic panels and bass trap

Insulation panels

Material used for panels are the same as in the case of side wall acoustic panels, but with bigger thickness (Nobasil NPM panel of 600x1000 dimensions with 200mm thicknes).

Side frame

Side frame has similar construction as it's in the case of acoustic panels determine for side walls and cloud position. Basically side frame of one stand alone acoustic panel is made up by the same construction but used twice and joined together by straight steel joint items.

Corners have been treated by wood putty and sanded. After that stained and optionally you can put on some layer of wood varnish to get better looking wood piece.

Front frame

Front frame has the same construction as front frame of the one acoustic absortive panel for flexible usage. Front panel is attached to the side frame by 90° angle brackets before insulation is inserted. Sorry about the picture quality but at the time I had no other option than use my cellphone under poor lighting conditions.

Back frame

For the back frame was first idea to use the same solution as it's in front frame case, but.. because front panel is fitted to the side frame by inner joints I had to use another solution in order to be able to mount the back frame to the side frame after insualation would be inserted. So I decide to use similar construction as it's in the case of front panels for corner bass traps. I have created smaller version of the frame and screwed them to the side frame from back side.

Chicken legs

At the end I made simple legs from the same laths as was used for fornt frame and piece of wooden prism of 50x50 profile. Few screws for the wood and it's done very easily.
