A stupid question, but I have no idea

[TRINADS]

What does SDA mean? I know its related to speakers, but I have NO idea what it stands for. Sorry for the newbie question, but it's killing me that I can't figure it out, and I keep seeing it all over the place!! Thanks!!

stereo dimensional (was dynamic) array. Best thing since sliced bread :D

See this site for a little more info:

Also, here's a paper Polk released about the SurroundBar, which builds on the SDA technology. Read the section titled "original SDA technology"

Actually, Stereo Dimensional Array.

Don't feel so stupid, I own a set and I still had to double check.

Strong Damn Animal cause that's what they are!

Oh man, I really do feel stupid. I have a pair as well... DOH!

[TRINADS]

Thanks!! I would have never figured that out. Good to know, I appreciate it!!

Don't go past the SDA explanation otherwise you'll go straight into Audiophile Hell.
Stay away from sda speakers. Don't demo,listen or look at a pair.
If you do, you'll be compelled to buy a pair, drive insane amounts of miles to acquire a pair and spend all your hard earned money getting better audio equipment just to get better performance out of them.
CONSIDER YOURSELF WARNED.

duly noted. I do have a pair of LSi15's for my fronts and the LSiC center with 2 pairs of the FXi3's for surrounds, just curious, as i'm just learning of these SDA's, how would my speakers compare?

Well, that seems to be the question of the year in the Vintage section. The sounds are very different (being completely different designs and components) and people will argue you to death around here about which ones sound better.

IMO, LSis are very crisp and clean. They are fantasticly detailed and really can't be beat for the price/performance when it comes to brand new speakers. SDAs are warm and very musical. They are also detailed, but completely different since you have the SDA effect.
The best thing to do is go find a pair of SDAs that you can demo or listen to and judge for yourself.

And welcome!

If you do this there is no escape for you - you will end up with a pair one way or another. I just bought a pair Sat. and I already can't imagine even getting rid of them; unless, of course, I was buying a bigger pair :)

As esavinon said, don't go near 'em unless you are prepared to get some!

SDA rocks. Though...your LSi rig is NOTHING to sneeze at.

I'm sure that there must be a polkie in the area that would be more than happy to let you get your demo on.

I've owned both LSi's and SDA....it's apples and oranges, really.

PS, Hi Al!!

[Fireman32]

I will own SDA's in my lifetime. Hopefully they will be the 1.2TL's. If your thinking about getting a pair you wont go wrong. And welcome to the club.

[reberly]

wow, I don't even feel worthy of looking at them w/o bowing my head. I had no idea what these speakers were all about until that link was shown above. My LSi15s look anorexic in comparison. I sure would love to hear SDA-SRS sometime. I'm guessing you need some pretty impressive amp's to make these things sing properly.

It would be nice if this worked with women. Oh wait it does! :D

Nominal recommendation from Polk for the SDA SRS (the biggest ones) is 1000 W/Ch. Yes, that's 1000 not 100 W! However, as has been said elsewhere, they will "sing" on far less power (esp. the smaller SDAs). I'm running 100 WPC into some SDA 2As and they'll go louder than I want in my small room - but these are the "baby" SDAs.

Why doesn't Polk bring a newly manufactured version of the SDAs back? Hmmmmm? Hmmmmm? Anyone? Anyone?
:confused::confused::confused:

I'd give 'em a whack for sure.

Many have asked that question :)

EDIT:

Additionally, what cost $3000 in 1987 would now cost almost $5500! Would you pay that much for a speaker? I know I can't afford to, and there's nothing functionally wrong with the old SDAs, and they're affordable!
