Sonus Faber Olympica III speaker placement

djfst

From the back wall, are these measurement to the front of the speaker (where the tweeter is, etc), or the back of the speaker? The Olympicas are pretty elongated so that would make a big difference.

I will start experimenting. On one of the side walls, there is a window that is difficult to avoid, so instead of being 3 feet from a "side wall," it is 3 feet from a window. Any suggestions on how much a side window will affect this and any suggestions overall?

Those 1/3rd or 1/5th measurement placements, are to cancel bass standing wave problems in rooms.

The odd ratios of measurements in my last post are to the bass drivers cone and from walls or very large sliding glass balcony type doors.

Tweeter direction angles are another thing again and are for imaging adjustments, and like I said I like the tweeter just crossing over behind my head.

This is what an Aussie, Neville Thiel (RIP) of the Thiel & Small parameters, that all driver/box are calculated on once told me, and it works a treat.

To try to cancel any bass standing wave problems, odd ratio measurements should be applied, never even ratios.

 Best: the third rule to the bass driver should be applied, and if that is not practical then 2nd best do fifths, 3rd best is 7th's

So for 3rds in a 22' x 16' = 7.3' from the back wall and 5.3' from the side wall 

For fifth's = 4.4' from the back wall and 3.2' from the side wall

Or you can use a combination of 1/3's and 1/5s'

You can't do much about the floor ceiling measurement, and your toe-in is up to you, I like the tweeters crossing over just behind my head.
