SDA SRS 2.3 Speakers

[ns4433]

found a pair of these speakers. guy is asking 750, what do you guys think of this model and what do u think is a fair price. thansk for the input

[Joe08867]

I like them alot. Very full sound for there size. I think the price is in line with the market. Have they been upgraded or are they stock??

[F1nut]

There's something wrong. The last pic of the back is not of a 2.3.

[Joe08867]

Nice catch F1. Looks like the back of a SRSII not a 2.3.

[candyliquor35m]

I paid $600 for a pair in fair condition and then less than $500 for another pair in better condition. I won't say how much less than :D

A friend of mine told me to never make a offer that didn't shock the hell out of the seller to see their reaction. Offer them $250 or $500 cash and see what happens.

Also there's a pair of SRS 2's for sale on here in the flea market for $400.

Nick,
Where is this guy located? If he is a local NJ guy lets go take a look if not forget about it.
The F1nut never misses a thing but as he ages things may change but for now you should ask the seller alot of questions. The label on tha back is the same as the one on my SRSII's.

FWIW. I checked my 2.3's right speaker and the label is identical, but serial is 3230.

[F1nut]

Identical to the one pictured above? I mean, I know Polk liked to use up left over stuff, but that label isn't even close.

[dorokusai]

That's awesome.

[Neskahi]

Yes. Just like it. When I first came into possession of my 2.3s, I had the boxes and they were marked 2.3 in big print. It always bugged me that the label read 'SDA SRS 2' and not
2.3.

[heiney9]

The first pic shows those are early 2.3's because they have the "donut" drivers. I suppose it's possible they have an SRS 2 label on the back. Polk didn't throw anything away apparently.

[heiney9]

If they are in decent shape $750 is a pretty fair price. I admit many of us are used to getting such great deals in the FM we tend to become a little jaded.

[F1nut]

I've never seen 2.3's without the donut drivers.

[ben62670]

The TL's had 4 stereo drivers, and 2 dimensional with the SL3000's. The older 2.3's had 2 stereo, 2 dimensional, and 2 bass (donut drivers) with the CL specials.
F1 don't you have 2.3's?

BTW $750, and you can pick them up is a great deal.

[F1nut]

H9 wasn't talking about the 2.3TL's, which I do own. He was talking about two different versions of the 2.3, one with donut drivers, one without.

The 2.3 and 2.3TL are entirely different speakers. It was not just a matter of simply adding the SL3000's that makes them TL's.

I knew that.
Really I did:p

[F1nut]

I know you did. :)

[heiney9]

I've never seen 2.3's without the donut drivers.

To my knowledge only the earliest 2.3's had the donut driver's added to the MW6513's. Later (non TL) models had standard MW6513's with out the doughnuts. Page 18 of the compendium II clearly shows a pic of 2.3's w/o the doughnuts in the 1st and 4th drivers.

The 2.3 TL are a completely different speaker they use all MW6510's and the driver array is completely different as well as the tweeters and the cabinets. They're 8 ohm as well.

Interesting.




BTW, the 2.3TL's are 6 ohm.

[ben62670]

Yeah the specs are misleading on a lot of the pin/blades.
"8 ohm compatible"= 6ohm nominal

[heiney9]

BTW, the 2.3TL's are 6 ohm.

My 8 ohm comment came straight from the Compendium II, I have found a couple other contradicting specs too. :confused:

It's not about the manhood; it's about putting up the correct info for others to use now and in the future. Plus, if there is an error in the Compendium I'd like to make a note of it. I realize the difference between 6ohm and 8ohm nominal is negligible at best.

[dorokusai]

And all this time I thought the Polk forum was about disinformation.....I better get crackin'

Bingo!

They are 6 ohm nominal. The info in the Compendium lists all the TL series as "compatible with 8 ohm outputs", which 6 ohm loads would be. Just a bit of marketing speak, I believe.

[dorokusai]

It's nice to see that you guys are capable of clear and concise help on this, moreso, your home forum. I hope it continues in other threads :D

[F1nut]

The same, the same.

Listen F1nutter Butter page 27 states and I quote "The Nominal Impedance was raised to 8 ohms" Seesh!! :D;) Don't you know anything?
















Anyways, the above response was meant in jest..... so Doro don't get your tubes all untied over it. :D :p

Waaaaaaaaaaaaaaaaaaaaaaaa

[F1nut]

LOL......yeah, yeah. My owner's manual says "compatible with 8 ohm outputs", so I'm sticking with 6 ohms. Someone here tested them, maybe Raife and IIRC they measured at 6 ohm nominal. :p

[hangon]

I just picked up my first pair of 2.3tl's tonight. Where can I find the interconnect cable and 4 tweeters for replacements?

[candyliquor35m]

I have 4 used but guaranteed not doa sl3000's for $120 shipped conus.

Have you swapped any of the tweeters around with each other to make sure the tweeters are bad?

[F1nut]

The pin/blade cable is no longer available, you'll have to make one. You can do that by using standard RCA jacks with the ground jacket removed as you only need a connection from pin to pin. What are you using for power? Is it common ground?

As for the tweeters, Polk sells a far superior silk dome tweeter now called the RD0198-1. The cost is $48.00 each, if you mention that you are a Club Polk member, with free second day shipping. I'd suggest replacing all 6.

That is true of conventional 6 ohm and 8 ohm speakers if their response is relatively stable over their response range. SDA's, because of their dynamic interaction, are not particularly well behaved in that regard.

They are 6 ohm nominal. The info in the Compendium lists all the TL series as "compatible with 8 ohm outputs", which 6 ohm loads would be. Just a bit of marketing speak, I believe.

I think part of it is marketing speak and part of it is technical speak. I had some difficulty trying to pin down Polk, Inc. on exactly what "compatible with 8 ohm outputs" meant. I had never seen a speaker's impedance described in such terms before. I wanted to know why Polk couldn't just state a numerical impedance value for the TL series as they had done with every previous SDA model. They seemed somewhat reluctant to discuss the matter in detail. However, I was told that:

"The TL series SDA loudspeakers are not 6 ohm speakers and they are not exactly 8 ohm speakers due to the interaction between them. The TL series SDA loudspeakers exhibit an impedance characteristic that is comparable to that of an 8 ohm speaker over a significant portion of their frequency range."

I assume/speculate/guess that the TL's have an average impedance above 7 ohms but a little below 8 ohms over most of their frequency range and that they would more accurately be called a 7 ohm (or 7.5 ohm :eek:) speaker, particularly when the effects of interaction through the SDA interconnect are considered. However, "7 (or 7.5) ohms impedance" looks oddball on the spec sheet, hence the "compatible with 8 ohm outputs" statement. Speaker manufacturers seem to prefer even numbers for nominal impedance specs.:)

I was unable to obtain an impedance response curve for the TL series since such information was, and still is, proprietary. Stereo Review magazine, whose reviewers seemed to be somewhat fond of the SDA series, probably would have done a review of at least one of the TL speakers if they had not appeared and then been quickly discontinued during a turbulent time in the magazine's history (1989-1991). Stereo Review always discussed the impedance fluctuation characteristics of the SDA's they reviewed in the "lab tests" section of the review.

The DC resistance of my 1.2TL's is approximately 4 ohms, which is the same as the DC resistance of my (6 ohm nominal) CRS+'s and 1C's. Therefore, for amp matching purposes, and because I don't like the thought of having "7 ohm speakers", I "pretend" that my 1.2 TL's are 6 ohm nominal speakers.

Perhaps one of the EE's around here will simulate all three (or five, counting the SDA CRS+ TL mod and SDA 2B TL mod) of the SDA TL crossovers in a software program (like PSPICE) and run some response sweeps.

[F1nut]

Works for me. :)

[hangon]

I am powering my 2.3's with a Cinenova Grande 5-channel 300 watts. Dennon receiver (as a pre-amp). I own the Monitor 10's and I am the original owner since the 80's. I also own a pair or rti12's and a cs350 Center. Out of all the speakers, the Monitor 10's have the best sound (for now). I am going to look into the rdo198-1. Thank you polk members for all your help.

[hangon]

I am not having any luck getting any sound from the center Tweeters on both 2.3TL's. Does the interconnect cable have to be hooked up for them to work, or is the polyswitchs bad? I have compared them to my newer rti12's, not as bright sounding (3 bad tweeters) but they have more mid's and Low's. I am really glad I purchased them. Thank you F1nut for everything.

[ns4433]

drew they are in nj

[deep bass]

I am looking at some right now, but they are the sda srs 2.3. Just a quick question is there a difference between the sda srs 2.3's and the 2.3'tls? If so how can i tell if i see them? Is $450 too low of an offer if seller is asking $700? (cant hurt right?)

[shadowofnight]

The differences between the 2 arent life changing by any means...it does go beyond just the tweeters though...do yourself a favor and read the many threads here on the forum pertaining to those and SDA's in general...you will benefit greatly from it.

Now, offering him 450....hmmm....just be ready for the kick directed at your junk...can't hurt if you make him miss :D

FYI, that would be too low if they are in good shape...700 would be a good fair price. Offer him 600...that wouldnt be too insulting.

[deep bass]

Ok will do. He says he wants to barter. I think i will throw him a low ball offer $500(almost 30% off).

[hangon]

I paid $600.00 for mine not too long ago with all 6 tweeters needing to be upgraded. I seen a pair of 1.2tl's go for $3050.00 on flee bay 2 days ago. So $500-600 is what they sell for and tweeters or drivers needed.

[BSUfbfan]

I recently won a pair of 2.3's, and after seeing the 1.2TL's going for insane money lately, I offered him the full price of $750. The grill cloth is a little 'rough', but the speakers and cabinets are in really good shape.

With the tweeter upgrade, I am at $1050, and we will see how they sound before I attack the crossovers. Can't wait for that pallet to show up Wednesday.....

[F1nut]

The differences between the 2.3 and the 2.3TL are actually quite a bit. The 2.3TL's have improved tweeters with a completely different crossover design, an improved cabinet, and a completely different mid-driver set up. They sound completely different.

BTW, there never was a 1.3TL, it's a 1.2TL.

[shadowofnight]

..it does go beyond just the tweeters though....

Damn it Jesse....he was given a homework assignment to search the forum for the differences...and you went ahead and gave him the cheater answer :rolleyes: :D

[F1nut]

Oops, I missed that one.
