Hi Roland,
Rather than one shopping list , I think I'll do an item by item installation of observations/suggestions .
You can either respond or just skip an item this way. It's also better for reference.
My setup; I'm going to make all the necessary measurements & commit them to CAD sometime in the next few days. In the meantime here are a few thoughts .
(i) My speakers are 1650 mm apart ( center of horn to the same ). This 65" spacing is about as wide as I can go in my place. It does works quite well .
(ii) Both speakers are focussed at a window. That point is @ 4300 mm away from each horn. Under that focal point is a table & lamp / no chair . In other words, if this is the sweet spot, then nobody gets to sit there.
(iii) My usual listening chair is to one side of this focal point. There is a duplicate chair on the other side ( of the center table /lamp ).
Both chairs hear ( or see the horns ) at an angle that has yet to be accurately measured ( this is where the CAD comes in ). It looks to be 10° to 15° off-axis
These 2 chairs also have a center to center postion of about 1650mm ( or center of a head to a head ).
(iv) There is a couch along the long wall facing across the room ( TV viewing ). This couch is also @ 15° off axis ( wait for an accurate measurement ) to the closest speaker . This couch , because of placement is "outside" of the imaginary rectangle created by the speakers & 2 chairs. At the far end of this couch is another location of great imaging ( making the couch a great place to stretch out & listen - ears are effectievly turned towards the speakers ) .
- A drawing will follow .
