Had my SVS for a while now but never got around to measuring my response as i was planning to move, the move has been hit with delays so i thought it was about time to have a look. The room is about 12' x 10' x 8' and contains all of the kit in my sig plus a computer, 2 monitors, a bunch of other av kit stuffed ontop of my wardrobe, some pictures on the wall, 2 shelfs with various books and magazines, cd and dvd rack that is full, more dvd's and cd's ontop of the rack and lying about, a mini fridge, bed side table and my double bed. I don't have any EQ device but i do have the small EQ on my SVS. Measuring was not perfect as it was only a quick test to try REW out and get a rough idea if i had problems or if i could make an improvment. It was quite a task to get the pc near enough to the av amp while being able to get the spl meter near to my listening position but i did my best. I must also mention i haven't made any adjustments to allow for my radioshack spl meter. So below is my response graph : In the end i didnt bother with any EQ from the sub as all i really managed to do was to get it roll off faster after 40Hz. I think the graph looks ok but im only starting to really dabble with this so would like any comments although there isn't alot i can currently do to adjust it at the moment. P.S. Thank good for the bag of cables making it possible for me to connect the av amp, pc and spl meter.
