Vandersteen 2C contour controls +-

As you move them closer to the front wall, try unequal distances from the side walls (the centerline of your listening position will not be in the center of the room) by a few inches. This asymmetry will help even out problem bass modes.

FWIW, I've gotten the best sound from my 2Cs with these dimensions:

(All measurements from tweeters)
Distance from front wall-12.5"
Distance from left wall-30"
Distance from right wall-40"
Distance between speakers-84"
Distance to ears, (measured perpendicular to plane of speakers)-120"
All walls and ceiling have acoustic treatment

I agree with most of the speaker placement dimensions, but isn't the 12.5" a little close to the front wall? Wouldn't this close to the front wall make the soundstage a little shallow? Just wondering.

@mr_m,
Rooms are all different in character, so one man's 12.5" may be 3 feet in another room. Another Vandy owner (ctsooner) had his Quatro's placed pretty close to the walls by JohnnyR. It didn't seem like it should work but it did. 
OP, let us know what you find.

I spent an evening moving and listening with the new cables... only to return to the exact placement where they were before. 6 months ago when I purchased the speakers I labored over placement and apparently I found the right spot for them back then.

26" off the front wall and 31" off the side. Exactly 9 feet to the listening spot on both. For the record, this is exactly where the Vandersteen manual "odd dimensions" placement would put them in my room. Length of the room, width of the room divided by 3,5,7,or 9. I tried them all and then some.

No toe-in, no angle back (I have the 6" stands so the tweeter is at ear level when seated.) Speakers are level and square. I tried them toed and angled but it was not as good. Behind the speakers are built-in bookshelves and record storage, full of books and records side to side, no gaps.

The 12.5" from the wall didn’t work well for me. But I have 16 feet in front of them to fill with sound. I could see how that could work in a shallower room.

I think letting the dielectric settle with the new cables is the right advice for now. I’ll post back in a week or so once I stop changing cables and just let it ride for a while. It sounds really good, but I realize I’ve been chasing an unknown spectre!

Thanks everyone for the interest and help.
