Velodyne ULD 15 Series II - More is better
I have had a ULD 15 Series II, in my system for years now and I love it. It never quite did my new home theater room justice though. the room is big (~22x25ft) and square, really ate up the base, always a bit of a "base hole" in the center of the room. I found a great deal on a 2nd, identical, ULD 15 and picked it up today
Running both subs, in front left and front right corners of room completely eliminated the base hole, the base level now peaks right in the center of the room.
Setting up the subs with a db meter, I get +6 db with both subs running over just running one at the same level. Obviously there should be +3 db by doubling the subs, but the additional 3 db is great, much more efficient now. Funny how that works.
Just thought I'd share.
