Not sure what you mean Makkapakka but rockwool is quite firm. The panel uses garden wire to hold the rw within the wooden frame and to strengthen it corner to corner. Not my best diy but a cheap test panel using spare rw and cloth.
Agreed BH the original thought was reflection of mid/high frequencies. They are easier to absorb and my feeling is that bass problems tend to sound like mid problems in that a muffled bass overpowers the mid. No science here, only intuition/experience. I found the bass traps cleared up a confused sound with complex music.
As to pillows & duvets I would say try them and if they help a little then a 'proper' treatment will be much more effective.

A rolled up duvet, placed upright should actually work fairly well in a corner.
@BigH I say that because the opinion of people so far seems to be that acoustic panels don't work. Down the left side of my room is a window with a large radiator underneath - at present there is nothing on the windows but we are looking to get venetian style blinds.

I used 4" thick sofa cushions about 2' square, some were filled with thick foam and others were feathers, did not make much difference if any to my sound.
Im interested by the comments that bass traps do not reduce bass.
@jiggyjoe Earlier posts from peeople seem to say that they don't think acoustic panels had any effect, so I am wondering if the problems lie elsewhere.
Bass is a little on the light side. Some people were saying this may be due to bass reverberating off the rear wall and cancelling out the bass from the speakers. I don't have a wall right behind me though so I suspected that was the result of lost bass. Turning up the bass control slightly seems to do that - I know that is an audiophile-no-no but its a compromise.
Jiggyjoe +1. Central seating is dodgy. So much depends on what we are prepared to do to acheive a home cinema system in a lounge environment. No answers but hopefully others suggestions help to find a compromise.
I find this thread of interest because those who ignore the room & only consider equipment will always be disappointed.
Right, I have few 'bought' panels and they have thin wood around all the corners to ensure the fabric can be pulled tight whilst not squishing the corners in. Some of the DIY examples on youtube are just a frame the exact dimensions of the panel and the panel is laid on top of it i.e. nothing at all on the front corners of the rockwool that the fabric is pulled over.
I've made corner traps (super chunks) but ordering some slabs for the rest of the room soon.
Acoustic panels do work, where did you get that from?
Windows are a problem, laminated glass will help if you ever think of changing it. I would get some thick curtains, venetian blinds I think will make it worse, vertcals blinds of a soft material may help.
Cant keep up with this thread! Bass with its (very) long wavelength and high energy suffers cancellation where high frequencies are easily absorbed by carpet, curtains, furniture etc.If two (loud) high energy waves are out of phase (as in reflected) the result will be no sound. (In a perfect scientific environment). In practice, ofcourse, it leads to frequency distortions, muddy bass etc.
I think even with an open ended room the reflective bass remains an issue. I am no expert and as always suggest experimentation to see what works before committing.
I chose for lightness to make a wooden frame from 4inch/4mm wood and steel corner brackets bolted. I tensioned the frame corner to corner with garden wire and ensured square. The 2inch rockwool then dropped in, one from each side. I then used wire to stop the rw from 'falling out'. This is not any recommendation, merely an explaination in making a lightweight panel. Cheers
Back to the op, Playing with duvets & pillows both behind the fronts and on the floor & walls should highlight the most important areas for treatment & then go from there. I was recommended a panel behind the setee but found corner bass traps far more.effective but every room is different.
Wanna buy some headphones??
@BigH in an earlier post I linked to these but someone said they may not work that well.
@Rob Yeah I just want to listen to music now!
BigH's link seems sound to me tho look expensive. I think everyones oprions here look good.
However, you want to listen to music???? Are you mad???? This is a serious forum!!!! Wake up man!!!!
Yes they are small and probably the wrong sort of material and thickness to do much good that does not mean all panels do not work. Thats like saying an airrifle will not kill a elephant but does not mean all guns are the same. You need to get the right tool for the job. I would do some reading of sites like this: http://gikacoustics.co.uk/testing-for-corner-bass-trap-placement/
