Using Polk sda-crs+ sideways. 90 degrees rotated

Just curious what exactly will rotating the crs+ 90 degrees will do to sound perception
If I understand it right, sda effect is to remove horizontal lobing . But bigger sda speakers with arrays of drivers most probably exhibit vertical lobing effect

You need to read the SDA handbook.Yamaha RXA1030, Yamaha CD-S2100, Yamaha AS-2200, Bluesound node 2i

You do not understand SDA..... At all.

This... Read up on manual & you may understand a little more understanding of what you have..

Alrighty now.

Well I guess that is one way to look at it.
So did you try it and turn them sideways?
What was your take away from the experiment? -
Well, we got the “least thought out” question OTY for 2021 JUST under the wire....
Turn it on it’s side and you lose interaural crosstalk cancellation, sport.....which sorta defeats the purpose of having SDA’sI plan for the future. - F1Nut -

Best answer by far. I can't help but laugh every time I think about it.

The soundstage is there, however it diminishes considerably. Now if you move them a bit further apart on their sides, the soundstage opens up a little more...btdtDon't take experimental gene therapies from known eugenicists.

Damn, you guys are harsh. He asked a polite question. Clearly did some thinking, just didn't have the right information to work with.I disabled signatures.

Lmao. You can do whatever you want. You could buy a car & state you want to drive it with 3 wheels. Other can say why would you do that. It was made to drive with 4 wheels. Why put up such a fuss & say r e t a r d people. Shame on you. This community doesn't need talk like thatJonathanPeterson wrote: »Not harsh. It's the usual over reaction of most retarded people.

So whenever there is an opportunity to prove 2+2 does not equal 4 they will make sure to spend extra time and effort showing their sharp mind that quickly caught the error In thinking that 2+2 = 3. Basically the accent is not on understanding or explaining of science but more on loud and vocal display that they know something accompanied by personal attacks. Chimps in zoos basically.

How dare you employ critical thinking? Don't you know "we are the science"?....sounds familiarDon't take experimental gene therapies from known eugenicists. -

Big bag of sailboat fuel.....again, if you understand A. what IAC is and B. how SDA deals with that in general and how the CRS's are designed in specific.....you would understand why it's not a well thought out question.
And for the record, it's not the "hey, what would happen if I turn my CRS on their end".....it's the steadfast, yet uninformed, commitment to the nonsense that followed.
That said, good luck with the whole crayon eating thing....I plan for the future. - F1Nut -
I asked the OP a question that has yet to be answered.So did you try it and turn them sideways?
What was your take away from the experiment?
-
There are many here who don't/can't get SDA placement due to room. Many have tried different things on their own. Try it. You may like it better who knows. Enjoy your speakers..

So, just how do the people in your life deal with you licking windows continually? Bulk discount on Windex and paper towels? Do they buy in bulk at Costco or is it a recurring delivery on Amazon?
All this because we know, in terms of what IAC is (and by default isn't) and how SDA (and other forms of IAC cancellation like Carver's Sonic Holography deals with it (passive or active)......and you don't?
I don't really have to read ANY books, other than the owners manual perhaps, to know that if I turn my CRS's on their ends, the IAC cancellation scheme goes right out the window......but don't take my word for it, just do it and you could have gone on your merry way.
Please tell me you aren't as dumb as you appear to be. If you can't say that, just stop posting.I plan for the future. - F1Nut -
Crosstalk cancelation that SDA is targeting is to target the issue where the left ear picks up sound from The right speaker and the right ear from. The left speaker.
The cancelation frequency and driver spacing is based around all of these factors.
When you turn the speakers vertical, you remove the part of the equation of how you hear.
So unless you intend to mount one to the ceiling and one to the floor and listen sideways, you probably won't find that oritentation to work as designed.
It has nothing with recording or microphones cross talking, blah blah.- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.
