Russ, I have already tried umpteen million times to explain that EVERYONE experiences ALL senses differently.
Why do some people associate pain with pleasure? Why does my wife love sour stuff and I hate it?

But to "them" hearing seems to be the magical sense that EVERYBODY has to experience in the exact same manner or they are wrong.

My rebuttal to "them" would be the words of the immortal Dr. Evil...

How about this. A farmer has a grove of green apple trees. The best tasting green apples on the east coast and he is proud of every crop every season. Lots of folks buy them because they are the tastiest green apples ever.
His neighbor in the next valley over has a grove of the sweetest, most recipe ready red apples. She takes pride in her trees every season. She has cultivated an apple that the finest bakeries in the world want.

They have both produced a similar product that their customers want.
Just a different flavor of the same basis.

Producers of music are farmers of sound. Cultivating a flavor. That Granny Smith is a humdinger of an apple. That Washington Red is a stellar apple.
They are apples, they taste different. But both of those farmers grew them to give them to you to enjoy.
No matter what kind of plate they are presented on.


Shut up and move on.

Russ must have stopped drinking, or his electro-shock therapy is finally working...

I don't know. So far in this thread we have plastic bananas, and now apples.

My question is why does it matter if the sound stage is the result of recording musicians as they play, or is created by an engineer. It is still a sound stage either way.

It is called a discussion.
Not everyone is going to agree, or feel the same as you or a few guys you know.

Ya know, be open to ideas, question what you believe, see how others feel or think.

Is that not the whole reason for the forum and thread?

Something we agree on. This thread was about helping someone understand differences between SDA models. Until you hijacked it with the same old arguments trying to start something...again.

The discussion was hijacked way back when a few started scolding several, including the O.P. for daring to call the SDA effect an "Effect"

Or did you miss that?

A bit of hubris here, no one was "scolded" nor did anyone get on their high horse and declare or insinuate that anyone should "dare" question. Your interpretation and yours only. No one can determine how you "read" into a post, which you do quite often.

You really need to let that chip slide off your shoulder and stop reading into things that simply aren't there.

SDA is not an effect and I think many including myself explained why. If you or anyone else want to continue to characterize it as such, that's perfectly fine. But, expect others to chime in with their own POV as well. The science behind it does hold up that it's not an effect. So far you haven't presented any solid info against that, just because you say it is. I am not saying this in a mean spirited way nor am I scolding anyone.......(had to say that since that seems to be how certain members interpret things)

Hey guys, anyone notice that in spite of what's happened with this thread, Shane's still decided to buy SDA's?!?

Congratulations are in order for Shane, now shopping for 1.2TLs on the East Coast.

heiney9

That's awesome, can't wait for his personal input after he gets then set-up.

Apples, bananas and plates . . .

I've seen a lot of concerts through the years here in the Akron / Cleveland OH area over the years. In the 70's Cleveland was a mecca for live music and a true launch pad, a must play market, for lots of bands. It's still big today.

Of the hundreds of acts I've seen, this discussion makes me think of two.

During my high school years, I lived very close to the Mothersbaugh's (one of the brothers still lives just a quarter mile away). In 1973, several of us would drive the few miles to Kent to watch Devo play. They had an old (Chevy I think) van they used to transport themselves and their gear to the dive bars they played.

When Pink Floyd brought The Wall to Blossom Music Center, on June
24 1973, my sophomore year of high school, at that time they were touring with SEVEN SEMI's full of gear.

I think when Devo played Blossom on July 18, 1997 they had a bigger van .

Here's the thing, both bands pretty much set up on stage the same way, dropping a drum kit in the middle and then feeding voices and instruments to a left or right bank of speakers (or both) based mostly upon where they were positioned on that soundstage.

We can talk as above about live versus studio, but that sound reached my ears from the left, middle and right side of the stage in a very real and specific way.

For me, modern SDA's seem to reproduce that soundstage best.

SDA's definitely rock!

I think that question was answered early on............now the thread has deformed in a different direction.....lol

Very much looking forward to finding a pair. Go big or go home, right!?

As long as you have a room with breathing room and they can be set-up properly. A large pair of SDA's that are in too small a room or can't be set-up properly will have issues. That was already covered in earlier posts, so I assume you have an appropriate listening space.

Congrats.

That's my thoughts, but like already stated....ya need the room for 'em.

Then rock onward and grab a pair. SDA 2's can be had fairly cheaply, my personal fav though is the 2.3's....tl's even better. None of them are slouches though, even the SDA bookies.

Word is, Polk may be coming out with a newer version of SDA speakers, so maybe save your coin or go all in on the vintage. Either way, enjoy.

shanedrew

Good to know TONYB. But after all the good work everyone has done here, I would want to hear a pair with all the new agreed updates. Hope to find a stock pair to perform upgrades on myself. But certainly would take a nice modded pair as well.

tonyb

If you can find a modded pair at a decent price, jump on it. The mods really make them a different animal than stock form. Happy hunting, let us know what ya find.

Good Luck in your search.
I would want a good properly modded set as well.
Let us know how the search goes.

You were right @nooshinjohn I am interested in this thread.

Let me state for the record, SDA is NOT an EFFECT.

@K_M in your first post you said effect 4 times, you are wrong, it is not an effect but a dedicated technology that was created. This is opinion, it is fact. In the SDA law listed below, no where in that is SDA listed as an effect.

@heiney9 was not trying to troll you, neither is anyone else on the forum. They are all trying to correct the notion that SDA is not an effect.

@aprazer402 quickly corrected the OP and others about how it is not an effect.

As for the new SDA speakers that you all are talking about, I can neither confirm or deny that is the case. Unfortunately Michael Ditullo has stepped down from his role as Head of Design and left the company. I can say, we are using SDA in our new Magnifi Mini Soundbar which is available on www.polkaudio.com and select dealers.

Now, the bickering and instigating has to come to an end. We have had many discussions about this and about how we need to respect each other. And I do not see it in this thread.

When it comes to SDA this is not we're agreeing to disagree to end an argument, SDA is not an effect, end of story. I urge everyone to read the SDA Law that I have listed below.

If anyone has further questions or comments feel free to ask myself directly and I will get you the answer.

@shanedrew, sorry your post has been hi-jacked. I hope you can find some SDA speakers in your area to enjoy!

Thank you everyone for your cooperation.


This is law when it comes to talking about SDA.

You're familiar with "stereo," the basic two-channel left-and-right channel separation of audio information. What you probably don't know is that reproducing "stereo" from a pair of loudspeakers is less accurate than it seems. In fact, it can be downright inaccurate. This is the problem that Matthew Polk and the engineers at Polk Audio set out to remedy in the mid-80s, just as the audio industry was transitioning from "boutique" brands, popular with a handful of hobbyists, to more mainstream popularity. It was a time of great innovation, and Polk Audio, already an established innovator, was on the forefront.

The problem with "stereo" was that it didn't really work. You sat in front of a pair of speakers, and your left ear heard stuff and your right ear heard stuff, and both ears heard information from both channels, left-and-right; each ear hearing information from both channels. It's called "interaural crosstalk." Interaural crosstalk occurs when left-channel (left speaker) information is heard by the right ear, and right-channel (right speaker) information is heard by the left ear. You can't avoid it, that's just the nature of sound. But it results in a completely unrealistic and inaccurate reproduction of sound, reducing the soundstage to a narrow "sweet spot," with muddy "stereo separation," and unrealistic "imaging."

To more accurately reproduce sound as it was originally created live, with lifelike imaging and separation, Matthew Polk realized the vital importance of maintaining the integrity of the channel separation. To do it, he had to defeat interaural crosstalk. So Polk Audio engineers designed a complex passive-circuitry crossover network for a new set of multi-driver loudspeakers. It would use patented algorithms and innovative sound-phasing to effortlessly cancel interaural crosstalk between the stereo pair. They called it Stereo Dimensional Array Technology, and it produced "True Stereo," a completely new kind of sound, where the left channel information is delivered to your left ear, while the right channel information is delivered to your right ear, and never the twain shall meet. Each ear hears what it is meant to hear, with full stereo separation, as if the performance you are listening to is live.

SDA Technology changed the sound of home audio loudspeakers. It delivered a dramatic, dynamic, broad, accurate, lifelike soundstage with pinpoint imaging and realistic reproduction. And Polk Audio's flagship SRS Series loudspeakers were built to deliver it at the most extreme, lifelike volume levels. Home audio would never be the same.

@KenCustomerService

I apologize if I bickered with anyone.
I truly find it hard to call the SDA.."sound" or whatever you call it anything else I guess out of habit.

I meant it as having the "Effect" of changing how it sounds compared to normal stereo, not as it Being an effect.

Either way, I get defensive easily...if "you guys" would chill out a bit, and not jump to the conclusion that I am arguing to argue, it might make things easier for all...I will try to also!
