I have a single 12” sub in an open ended approx 15x25 room. My first location produced bass 20’ away but very little in the listening area. Moving the sub only a foot and a half, close to a wall ( 4”) and experimenting with forward and side firing (into a corner worked best) produced smooth response in the listening area. The sub is across the room from the main speakers (Wireless helped here). Placement next to the mains seems intuitive but may be just the wrong thing for your room nodes and it’s not necessary if the crossover is set properly. Good luck!
Lots of bass at walls, lack of bass in center of room/listening position
I guess this is relatively common in listening system. Is there any way to smooth this out so I get more bass energy at my listening position? This happens with our without my 2x 18 inch subs. Room is 12 x 16 x 8 ft, speakers 4.5 ft apart on long axis and I am sitting 4.5 feet away. I tried moving back and forward but the entire middle center of the room except near the walls has decreased bass.
Is this a boundary effect or could it be due to bass cancellation effects?
