Hi. I took delivery of my new SB12+ sub last Friday, and have just been playing with various positions and REW now Ive a day off. This is my 1st sub and time doing anything like this so would like any advice.
Ive tried 6 positions for the sub and have generated response curves for each. In each position I re-ran the input calibrate and input volume setups in REW. These are the 6 graphs Ive got. Which is the best? All controls on the back are off. Only the gain has been changed so far on the sub and left in a fixed position for all graphs.
Position 1 = in between front right speaker and TV stand facing forward
Position 2 = Along right wall ~50cm forward of front right speaker facing diagonal into room
Position 3 = Along right wall ~50cm from rear right speaker facing into room
Position 4 = Along rear wall begind sofa next to center rear speaker
Position 5 = Under staircase in middle of left side of room facing across into the room
Position 6 = Under staircase in front left corner of room facing diagonal into room
I dont think the overall gain level in all positions is quite correct, but i suppose its the shape which is more important at the moment; I can change the level after the response shape is better. Comments and recommendations welcome.
