    Is it hard to sell a pair of speakers or what? :'( Bump for a very fine pair of RTA-12's

    Well it has been 4 years or so since I had these up for sale, and I am putting them on the market again. They just don't get much use and they need to be enjoyed by someone. Price is $550 and pickup only in zip code 60914, or I am willing to drive a 100 miles or so to meet.

    If somebody could only hear how these GREAT speakers sound. :p

    It's UNBELIEVEABLE how much sound comes from 4 woofers and 2 tweeters and the 2-12" passives. It boggles my mind! I've owned a hundred sets of speakers of all makes and sizes and my RTA12b's are in the top 10 for sure. <3 And the top 10 includes a few sets priced in the 3k to 7K range. That should shine light on their capabilities.

    And these have a Left and Right designation. The sound-field is HUGE! A real jaw dropping performance.

    And to add your rebuilding and veneering those beauties has to make them the BEST ones on the planet.

    Yeah, these are a very fine example of RTA-12B or C. If only I didn't need an AVR and you weren't so far away.

  • Hello fellows.. Faustin I was wondering if the top hats for your 12cs were always uniform. I have some 12bs that have deflated tops and was wondering if you had and pictures of how you fixed them (if you even had too). I've had ideas but wanted to see how others fixed them

    Fortunately the tophats on mine were in pretty good shape. The fabric on mine are held in place by a rubber spline, the type you would use to hold a window screen in place on the screen frame. I hand washed the fabric and let it air dry. IIRC, I glued/renforeced the tophat frames and that was it. I have seen other people repair the frames with wood dowel rods etc.

    If I had room I’d come get them.... and keep the ones the same model I have😂😂

    OMG! I can't believe these are still here. Forget SDA. These are the cream of the crop for Polk. I had SDA SRS II and the 12B. (SRS II long gone) I still have the 12B and they are the reigning champs and one of only two main speakers (Infinity RSII being the others) I keep. The Wife has something to do with that. However the 12B and 12C are some of the best I've heard.

    If you want a true audiophile speaker this is it!

    Especially with all the custom work! These are so worth the price.

    As a near-Indy resident, these present a very tempting alternative to fully restoring my 7B's right away...

    The 7's are a very nice book shelf speaker, (I have a set of them fully restored) but there is no comparison between the 7's and 12's. 7xy9lldg0uz4.jpg

    Are the 12's that much better? Considering the size of the stands I use, probably wouldn't much of a difference in floor real-estate.

    YES, the 12C's are in another league. The major league!

    I agree, since I've owned 2 sets of 7's and now own 12b's. The 12c's I assume are like my 12b's and present a monstrous sound stage and bass that can vibrate a 21X18X16' high ceiling room's wall and stuff on shelves.

    Now the 7's could be considered for intimate listening and do sound very balanced for sure. For volume, the monitor 10s are great for that. But the 12s take sound to another level. ;)

    Both are nice but think of this...the 12C's have a left and right designation for the pair. They are truly amazing speakers! B)

    You guys are really selling me on these. Note: I am in a pretty small room - 12x13. Should that affect my decision? I intend to move to a bigger space later this year.

    The RTA12C's and RTA15TL's are on my Polk Most-wanted list. I really liked my Monitor 8t's.
  • Tony MTony M Posts: 9,461
    I have never had a Polk speaker system in my smallish home. wait...I do have Polk M3's and M5's for rear speakers in 2 systems.

    I've only had all my other many Polk speakers and subs out in a separate building with the dimensions typed above.

    Sorry.

    Maybe somebody else has had the RTA 12 series in your size room. ;)

    Tony,
    What is the difference in the 12b and 12c? Thanks!

    I'm pretty sure the crossovers are exactly the same and the only difference is the tweeter. Which seems weird that it's the only model that changed drivers but kept the same crossover. Or maybe I'm remembering incorrectly.

    IIRC the difference between the 12b and 12c is the tweeter and perhaps going from a fuse to a polyswitch. In regards to the room size, I would think a 12'x13' room for the 12's is going to be fine, though they are capable of filling a much larger room.

    Hey Bruce ...
    Back in the late 80s my friend filled a VFW hall with music from his 12Cs. IIRC, it was a good size hall. I’d say30x30. Cannot comment on the SQ, but we danced all night 🤠

    12x13 ?

    I've seen some 12b with poly switches. From what I was told the later 12b and the 12c had the poly switches. I've also seen the crossover on the 12c speaker marked as12b. So it appears they used the same exact board.

    I dont think the crossover have the exact same values though. Since the 194 tweeter upgrade was sutible for 12C but NOT the 12B with peerless tweeters.

    IIRC, when I looked into a 194 upgrade for my 12b it would have required a crossover adjustment. I think adding a resistor and maybe a cap value change. I might be confusing the tweeter upgrade with a 198 upgrade on my 11t.

    But I know I was discouraged by many on replacing the peerless with a 194.

    The RTA12C has a fantastic favor amongst audiophile reviewers.

    I still have my 12B and am pretty sure I'll never sell them. For the price FAustin is asking for his, rest asure, you would be getting a effing fantastic speaker for the price. Mine dont look near as good as his and I'd be hard pressed to let mine go for his asking price.

    If you have never experienced the 12B or better yet the 12C you dont know what you are missing!

    With the 12B I dont even use a subwoofer and the imaging is insane. You will swear your center channel is playing. (If you have one)

    Ain't that right @tonyb ????

    After spending several hours listening to these the other day, I have decided to not sell these. No longer for sale.

    They look as good as they sound too. I wouldn't get rid of those.
