Hey thanks for the suggestion. I was going trhough your system photos trying to figure out how to adjust bass traps. Well I am kinda confused. Since I am completely new at this I guess I have to youtube it over the next weekend.
Bass traps are not adjustable as such except to add more or less of them ie larger. The science is to cancel reflected bass which leads to muddy bass and wave cancellation. They therefore are mis named in that they increase rather than decrease bass. Several threads suggest throwing duvets & pilllws into corners to see the effect but obviously this only provides an indication of what could be achieved
