First the story...
I recently replaced a Velodyne CT-80 sub with an HSU VTF-2. Put the new sub in the same location where the old sub was, front of the room left corner. Sounds a lot better, more than just the one-note performer I felt the CT-80 was. Still not that impressed with the 'feel' of the bass. Time to take out the new SPL meter and see what's going on.
Nothing is going on below 35hz from my listening position. I'm down 6db (corrected for meter) at 40hz, and 35 and below don't even move the needle. Before I ordered the sub, I had sent HSU a layout of the room, and of course they suggested placing the sub directly behind the listening position. So I drag the sub over there, frankenstein some cables together to reach the new location, and re-test. Holy rumble batman! I'm level at 40, 31.5, and only down 1db at 25.
So I throw in the Hulk and settle down to check out the new setup. After waiting what seems like an hour for some kind of LFE scene, Bruce finally transforms and wrecks the lab. Oh. My. God. So that's what I've been missing! After the movie, I turn on the lights, and notice that 3 of the hi-hats have dropped about 2" from the drop ceiling. Hee Hee.
Now the question...
The room is 22 feet by 10'4", with a 7.5'x7.5' opening on the front right side for a 'snack bar' area (picture the room as an upside down L). After trying the sub in about 10 locations, the most even response is indeed right behind the sofa (about 16 feet from the front wall), nearly adjacent to the side wall. However, there is one little problem with this location. From my sweet spot (about midway L-R in the room), I'm down almost 10db at 50hz. From the other prime listening spot (next to me on the couch, almost adjacent to the wall the sub is on), that same 50hz is UP almost 10db. Every other frequency is about the same. FWIW, I didn't notice a huge difference while listening to Toy Story 2 and Hulk from either location. Thoughts?
Here's the layout of the room:
