I've been following this as well so thanks for updating.

Yeah, I've noticed myself that it's different with the speaker near the wall. A 2pi vs 4pi thing I guess (radiating into half-space vs full-space)

Cancellation of between 100-200hz off the front wall depending on how far away the wall is. Placing the front speakers right up against the wall is your best bet if you can't treat the wall.

This was the resistance difference I was referring to, not the 0.4 ohm difference mentioned in an earlier post.

Regardless, I'm glad you are happier now with the Titans. After all, that is the bottom line.

Here's a quick comparison between the two..

I need to swap places with each other and re-run it, but I'm tired of moving these heavy things..

Measure one speaker at a time.

Ya acoustic panels wont fix nulls. I know from my experience in my space. My room has some nulls in a similar band of frequencies and it took a lot of trial and error with different bass management schemes to get the best results as well as proper toe-in. I tried a few different models of speakers until I learned more and figured out I had nulls in my listening/watching center seat.

So I moved my theater chairs back about 8 inches and it moved them out of the null and made such a huge difference. Just like the dude who was at the THX seminar said; deafening all around the room except roughly the center of the room and thats about where I had my seating; if a bit more towards the back of center a few inches. Im now at a bit behind the 2/3's of the room point.

As has been said small room acoustics are no joke especially with dimensions that are squarish.

Any updates? Something like these will come in handy until youve nailed positioning.
