I went around my room today with one sub running a 30hz tone placed in the listening chair . I went around the room and identified all the hotspots with an iphone app like a spectrum analyzer. I like being able to reach around high and low to see actual numbers and readings. Directly behind my seating area there is a wide stairwell going downstairs . I found a few 30hz hotspots down there. I put one sub there to try it . It really brought up the deepest bass impact without a ton of volume. Placing the sub as Tim suggests in the listening seat is a must . The whole room is your subwoofer after. Its amazing what even one 10” is capable of with accurate room placement . I’m starting to think my dual 18” could have been more 10” instead . Although the nice part is i can dial them back and still achieve 20hz with authority.
Been a very eye opening topic.
