Happy Birthday, I've seen what you do for the GTG's can't imagine what a Birthday bash there is like.lol
happy belated birthday, Ivan.
Iris is babysitting her grand kids for most of the day on Sat.
have any particulars on a time frame for SAT?
Thank you guys
Your query is valid, just the math off. The 3 angles of a triangle always add up to 180°. Therefore the equilateral has 60° angles (±30°). The 45° angle for stereo you refer to is ±22.5.So it is! So I think my query is moot.
What an incredibly useful coincidence!Rule of thumb
Say you have 2 rows and you set the 1st row such that the angle between the [email protected] mains and the listener is 60 degrees (+/- 30).
And then you want the 2nd row to have an angle spread of 45 degrees (+/- 22.5) between [email protected] mains and the listener. The spacing from 1st row to 2nd row is 1/3 the distance between the L&R speakers.
This rule of thumb will place the 2nd row about .6 % short of "exact". Call it 1 inch shy for a 10 foot spread on the mains.
I've always heard recommendations for a 60° spread for 2-channel music and a 45° spread for movies (to mimic the spread in movie theatres).Home theatre asks for the L/R pair to be 30 degrees off the center line from the MLP, whereas most stereo room recommendations I've seen ask for an equilateral triangle between the L/R speakers and the listener, so with a 45 degree angle off center for the L/R pair.
The few home theatre designers I've met placed the L/R speakers for preferred soundstage width or for mode cancelling, depending on their priorities.Have dedicated home theatre builders tried to split the difference, or just go with the home theatre specs and call that good enough?
