Basement room-Acoustics Forum-Acoustic Fields Forum

I have a basement room which is W = 4m (13.2ft) H = 2.4m (7.87ft) D = 4.8m (15.74ft) with concrete wall sand ceiling, 5 small window high up next to the ceiling which are (1m (3.2ft) x 30cm(1ft) I´ve laid a thick carpet on the floor. I´m using Infinity IRS Beta. My sofa ot listening position is 0.5 (1.64ft) away from the back wall, My IRS Beta panels a almost a third of the way into the room, my bass tower i´ve also pulled into the room away from the back walls. I don´t play loud, just enough for someone the raise there voice (not shout) to be heard. Here comes the next part, i don´t really know where to start with my acoustic treatment??
