It's good to know you've already experimented with this. My 500s are currently on the inside. I am still concerned though because ray tracing tells me the listening window curve will be affected. The backs of my actives are 3 feet from the front wall.

The front centers of mine are currently 4.5ft from the back and 4.5ft from the sides. They are spaced 12ft apart. MPL is a bit closer then I like at 10ft from the front centers but it seems to work. The stage is quite wide and presents a fantastic image with well recorded stuff (although I’m not sure they intend it to be that wide). Some music I need to listen to again on headphone and/or a more conventional setup because image wise what I think was intended as room reverb sounds weird as the room is in front of me and not around me.

The benefits outweigh the drawbacks. I wouldnt sweat it. smile Less cabling all over too since you are poaching signal off your towers.

Trevor, I think you think that the front subs in an active LFR set-up are fed high level from the speakers. They are not. Each DSP box has a sub out low level with 0, 40, 60, 80, 150 Hz cut-offs. 0 means the actives play full range. You can of course control the sub's range via it's own cut-off rotary switch. The lows are absolutely awesome.

One thing that is missing is a relative "sub to LFR distance" adjustment. The sub therefore can't be placed further from the MLP than the LFRs.

Rich, there's nothing wrong with your 10 foot MLP. I just tried 10 feet with mine and it feels like I am closer to the stage. The center image is larger and so are other images across the stage and I feel more envelopment. Unfortunately, I also find the cabinets (?) of the actives create an acoustic shadow that limits the soundstage width. Of course that may be rectifiable via more or less toe-in.

When I move back to my 14 foot MLP, it feels like the stage is "up there". The images haven't moved but they've become smaller (which can be enlarged with more volume to a certain point before depth starts collapsing) and the soundstage width expands and I can now hear behind and to the outsides of the actives. This is my preferred listening configuration but I have to say that closer up is also addictive in its own way. Now I gotta get me a sliding chair so I can adjust it depending on mood. smile

What is your toe-in?

I’m not down there at the moment but think it’s something around 10 degrees.
Anyway, I just setup the VP180 to give it a spin as the virtual center is only good for 3 seats. 4 seats seems to depend on what’s being played.

I’m going to set everything up on the short wall soon and test that out for a while. It will definitely improve the surround setup as It’s really too tight front to back using the long wall.

My virtual active centre is also good for 3 seats.
