HI all,
I'm working (seems like constantly
) to get my room and system where I want them to be. I've decided that tailoring the crossovers, etc, to my listening position isn't something to be avoided since my horn setup allows me to do that. Much more directivity to the sound than with conventional speakers, so this could get interesting.
What I'm seeing is a suck out around 6-8kHz. I do have Risch-recipe traps and panels in the room. There were two panels, 4" thick stuffed with fiberglass, at the FRP. I have tried removing them while watching the RTA but didn't see any change. I did have a xover pole at 7kHz so this could be some phase cancellation, but I'm pretty sure that this frequency range is always a problem in my room. Is that normal for most home listening rooms?
My room is a finished basement with one side wall and the back wall built 4" in front of the concrete slab walls. The front wall is a 6" framed exterior (walkout basement) and the remaining interior wall is just a 2x4 partition with insulation, but the back side of the partition is not covered. The ceiling is a typical drop ceiling and is about 2" under 8'. The horns are along the long wall (the exterior wall), about 8' apart and I sit about 11' from the mouth of the midbass. Behind me is the 15x14 "shin" of the L-shaped room so I'm sitting at just about 14', in line with the short wall that makes the L.
I can post drawings and RTA plots later when I get back home if they would be of any value. Also, I'm finding the horns have some different characteristics to work with as far as room response.
TIA!
Dan
