Need help with Polk Speaker ID.
New here, member over at Audiokarma for a while, but figured you guys are the Polk Gurus!!
Found these locally, but person selling can't find any model numbers. Told them to look at pack near terminals, but the only numbers were:
Polk Audio 11 1625 & 11 1980
Any ideas?
Thanx,
Robbie

it's just a guess without taking the grill off so we could see the speaker.
SDA2a -
Polk SDA2. My guess is the original model with dimensional tweeters.
Take a shot with the grills off if you can. -
I guess the best choice is to go by and take a look. I have owned bookshelf Polk's in the past, but I'm just not familiar with their Floor Standers.
Any pointers, other than the usual?
Are they any harder to refoam?
How would they compare to my
DCM TF600s
or Boston Acoustics BA200
Thanks for you input -
Lasareath's site (polksda.com) says there was such a thing as a Monitor 11, but I'd guess also that they are some of the original SDA II's. As stated, the best way to tell is to get a pic with the grilles off or a description of the driver complement (number and position of tweeters and mids and whether the big passive radiator at the bottom has a flat foam disc covering the entire face of the PR or part of the cone is visible).
You shouldn't have to worry about re-foaming because Polk used butyl rubber for the surrounds. There are various tests you can perform to see if they are in good shape. You can gently push in on the face of the passive radiator and hold it to see if the mid-woofers push out and how long it takes them to recede. This tells you how well sealed the speaker is. (They should take at least 10 seconds to recede.) If any mids don't push out, they could be frozen because of a damaged magnet, which requires replacing the driver. If they are the SDA speakers, a special interconnect cable is required to run between the speakers. If that cord is missing you'll have to find or make one. -
I have a question. How much is he asking.
Anything over $250.00 I would say walk away. Unless they are in pristine condition. And looking at the pic I would say they are probably in decent shape maybe. Considering the Polk Audio tag is falling off.
You can find the newer SDA2B for around 250-300. -
I appreciate the info.
Took a quick peak at the polksda website. It seems if they do not have the interconnect that they are going to be useless, at least for me?
Looks they are asking 100.00. -
Aren't those Monitor 11s?
Those have rubber surrounds no foam.
EDIT: Opps, neverminds.....

halo and F1 you guys are right. Oops!!!!
With that said 100 bucks for Monitor 11's is a good deal in my book. Anybody else? -
would they be better than 10s at the same price?halo and F1 you guys are right. Oops!!!!

It's not falling off. The logo is held on with one pin in the center, therefore it gets out of whack easily.
Great speakers, kinda like Monitor 10's on steroids with better bass, Peerless tweeters and distinct left and right channels. At $100.00, they are a steal.Political Correctness'.........defined

A pair of Monitor 11s sold on e-bay in 04. The photos look identical with the Monitor 10 with the long grille. A pair that look like the ones in question sold on e-bay and they have the short grille and flat passive were called SDAsTO ERR IS HUMAN. TO FORGIVE IS CANINE.

Those are without question, Monitor 11's.
I had thought that he just mis-read the roman numeral 2 as 11 instead of II
good catch F1 if it is I still want to see the face with out a grill the M11 have a cone passive woofer from what i saw on the Polksda.com site....whats with the "fluid coupled woofer" I now they use that on tweeters to cool so i would think it is just to slow down the woofer. Why not a weight like the other passives in the polk line up? -

Why would they have distinct left and right channels? -

The pictures on the Polk SDA.com site from that eBay auction are not like any Monitor 11 that I have seen before. You need to keep in mind that what is on that site is not always correct as other errors are known. That said, they might still be Monitor 11's, but of a later vintage as they are sporting the SL2000 tweeters and cone PR's, while the Monitor 11's that I have seen use Peerless tweeters and flat PR's.A pair of Monitor 11s sold on e-bay in 04.whats with the "fluid coupled woofer" I now they use that on tweeters
That's a "fluid coupled sub-woofer", which is another term for passive radiator. The tweeters do not use a fluid coupled anything.IIRC they're imaged loudspeakers; the interior 6.5" woofer is for midrange and the exterior 6.5" woofer is tuned for bass.
That is correct. One mid-driver per cabinet has acoustic foam mounted under it to tune it for midrange. The other is "open" to allow it to couple with the PR.Political Correctness'.........defined

I have owned Monitor 11s. Looks just like them. The fact that it says Monitor 11 on the rear sticker is a dead giveaway. $100 is a decent price.

Old saying, you snooze and you lose.
They sold before I could get there yesterday.
Darn it!
I do appreciate all the guidance, though. -

yes i knew Polk never used Ferro Fluid tweeters I was just stating I had known other manufactures did on the tweeters to keep the VC cool.
I had just never heard the term used in a passive woofer situation
Jesse your a fountain of info my friend -
To avoid further confusion...... Polk has used ferro fluid in their tweeters, but the term fluid coupled would not apply to the use of that material. Fluid cooled would be the proper term. Polk was trying to describe the relationship between the mid-drivers and PR, which are coupled by air and since air contains water molecules, they used the term fluid coupled.Political Correctness'.........defined

Actually, air is a fluid, and not just because it carries water molecules. It can't be considered a gas, because it contains multiple gases bonded together.
The "fluid coupled" woofer is only fluid coupled because of the sealed cabinet forcing the air to move the passive radiator.
Ferro fluid is a liquid with ferrous material that can be used (among other things) for cooling tweeters. Wiki!
"Ferrofluids are commonly used in loudspeakers to remove heat from the voice coil, and to passively damp the movement of the cone. They reside in what would normally be the air gap around the voice coil, held in place by the speaker's magnet. Since ferrofluids are paramagnetic, they obey Curie's law, thus become less magnetic at higher temperatures. A strong magnet placed near the voice coil (which produces heat) will attract cold ferrofluid more than hot ferrofluid thus forcing the heated ferrofluid away from the electric voice coil and toward a heat sink. This is an efficient cooling method which requires no additional energy input"Ludicrous gibs! -
I would have said that these were the SDA2's.Statistics show that 98% of us will die at some point in our lifetime.
The other 2% will work for WalMart. -
There ya go.Actually, air is a fluid, and not just because it carries water molecules. It can't be considered a gas, because it contains multiple gases bonded together.

I just can't let this quote in good conscience go...
1) Air is a fluid; gases and liquids are fluids. Pretty much anything that flows.
2) Air doesn't carry water molecules (water vapor). Multiple gases constitute air including water vapor.
3) Air is gas. No buts ifs what not. If air ain't a gas I don't know what is.
4) Air does not contain multiple gases bonded together. They just are there in air in varying proportions.

I at least got the fluid part right... do I get a point for that?Ludicrous gibs! -
