I picked up a couple of Auralex LENRD bass traps to place in the corner of my room. This is my first stab at room treatment. I have an odd shaped listening room with half of it covered with carpet (the main listening area), the other with marble kitchen floor. The dimensions are 14 x 27 x 8.5 with two large openings into a room twice that size with cathedral ceilings. Very difficult room to pressurize.
Is it a good idea to place the LENRD in all corners of the room, both ceiling and floor, or are there specific locations that should be addressed first? Also, what good, cheap adhesive should I use to mount them to the wall?
