  1. Hello, I've had an SW-12 since 1993/1994. It had been working very well until about two weeks ago. About two weeks ago, it started making two kinds of noises after it gets warmed up for a while, like 6 - 35 minutes. One kind of noise is static-like and the other kind is what I'd call crackling kind (could be the sound of clipping). These noises come on whether any source is connected or not. Until these noises come up, the subwoofer appears to work as good as before. Once these noises start, none of the controls (LEVEL, PHASE, and LOW PASS) has any aural effects on the noises as far as I can tell. I've plugged the power cord of the unit to many different wall outlets in my 2-story house and also with or without my computers, cable modem, router, etc. ON, and the problem shows up anywhere. So, I'm leaning towards ruling out things like ground loop or interference from Wii-fi, etc. as the cause of the problem. Even after the noises show up, the source material keeps getting reproduced as usual. I suspect the problem has something to do with overheating of the amplifier because they don't show up immediately after I turn the unit on. Also, I found one area of the top plate of the plastic cover that covers the amplifier has a sign of getting soft before, but I have no idea when it happened. I have connected the speaker leads inside to a regular speaker and the noises came on, so I'm ruling out the problem lies with the subwoofer's speaker unit. I have cleaned the pots for the controls fairly well, too, so they're probably not causing this problem either. I'm now concentrating on the amplifier. As a starter, I downloaded a service manual of SW-12 and SW-15. It's here: http://www.audiolabga.com/pdf/SW12-15 I.pdf Pages 15-17 are the schematic of SW-12. The top portion of Page 16 (Sheet 2 of the schematic) is the part I'm concentrating on [labeled DRIVER CKT filter driver bd.] now because the location of the cluster of 4 transistors (Q7, 8, 9, and 10) coincides with the previously softened area on the amplifier's plastic cover and also the area on the circuit board these four transistors lie on is not burned badly but dark brown. (Each of these transistors has its own little heatsink, so they are probably known to get hot, but maybe with my unit, they may be getting too hot to affect the performance of other components in the amplifier.) Now, I'm completely clueless when it comes to electronics. I'm hoping that someone here can help me with questions I have about the schematic and electronics in general. Tonight, I removed the amplifier and measured about a dozen resistors' values with the unit turned off without any source signal being fed to the amplifer. Since my multimeter can't test capacitors, I'm not going to mess with capacitors now. Obviously, I don't want to remove any components from the circuit board to take their measurements if I can avoid. As far as I could tell, there were no apparently damaged components or suspicious solder joints. Four resistors caught my attention, though: One is R45 1M. It's first resistor on the DRIVER CKT (on the left on the schematic). When I take a reading, the value is only about 109K. Here is my first set of questions: 1. Do I need to remove at least one end of R45 to get an accurate reading? 2. If it's faulty and I install a good one, would it make any noticeable difference in the circuit? Two other resistors which give different values than the specs' are R74 and R73. Their values should be 2.7K ohms according to the schematic and the parts list in the service manual. My meter reads about 1.42K ohms. Here's my second set of questions: 3. Do I need to remove at least one end of R74 and R73 to get their accurate readings? 4. If they're faulty and I install good ones, would they make any noticeable difference in the circuit? And here's my final question for tonight: 5. If you were tackling this problem, where would you start? Thank you in advance for reading this post and possibly offer some answers/advice/suggestions. Happy Listening! ------------------------------------------------------------- Additional comment: The main heatsink on the back of the amplifier never gets hot. It remain just mildly warm. On the other hand, the small heatsinks on the four transistors on DRIVER CKT get too hot to touch.

  4. Hi guys just like the title says... I'll entertain new or used. If you have another sub you have had great experience with that you are selling I will look at those too! Thanks everyone
  5. Hey everyone! So I just ordered a R-115sw and after doing some measurements it would probably work better for space issues if I had the R-112sw instead. If anyone has a R-112sw and wants to upgrade I would like to trade. If not, I'll do fine with the R-115sw and have to manage . Anyways, your used R-112sw + $250 for my brand new sealed R-115sw. I am located in Southern California. Thanks for reading!!
  6. I have recently bought the Klipsch Home Theater RP-F280 system. I am planning to drive them using a Yamaha RX-V781. The speakers are 8 ohms and rated at 150w RMS/600w Peak while the Yamaha Amp delivers 95w RMS at 8ohms. Is it a good match? 95% of people told me it's ok but then came along a connoisseur and said that having a lot of head room will blow a tweeter or two at high volumes as the amp will struggle and send clipped wave forms that can damage or will probably damage my speakers. I really need some expert advise Thanks
  7. Hello Everyone: Just joined today because of a problem that i hope someone can help me with.1 Tweeter in my Klipsch LaScala is not working,i am the 2nd owner and i have have them about 10 years no problems until now.Is there any repair places to send it to to make sure it is the speaker itself,solder problems? Could it be the crossover? Need some help please.Not really an electrician,just love the sound when all is well..Thanks Mark
  8. Hello Community =) i attached my plan for a home theater what do you say about it? btw. the sw 12s are under my couch

  12. I'm currently running an all Klipsch 7.2 setup for my home theater and have been looking at upgrading my current AVR to take advantage of the new sound mixes now available (ie. Atmos, DTS:X, Auro 3D). I have been doing lots of research all over and I'm having a very hard time making a decision. I am needing some recommendations from all of you but I'd like to avoid "fanboy" recommendations. I know this may sound silly or somewhat counter-productive when asking for recommendations, but I want the advice to be based on both the kind of hardware I am currently running and also on objective information. Just because someone has always purchased a specific brand for 20+ years should not be the only reason/justification as to why they recommend it. I know MANY of you have a wealth of knowledge; far more than me, on what the pros and cons are of various brands/models and can also explain objectively what I can expect with a certain option. I also am not looking to go crazy expensive with flagship models and because of this, going with brands like Anthem or Emotiva are probably out of the equation. As of recent, I have been entertaining Pioneer, Marantz, and possibly Onkyo again (not Integra just because it's Onkyo with nothing other than a different name and higher price). My concern with Onkyo has been there prolonged history of bad boards having faulty HDMI outs (seems like this is going on like 5 yrs, yes?). I will add though that my only experience has been Onkyo - I've been pleased with the sound but wouldn't know what I am potentially missing out on since I have not heard another brand. And in doing my research I have found many mixed review regarding some of their recent models (ie. 646, 656, 747, 757), and many people stating that the build quality has gone down hill. Is this really so? So, here is my current setup to give you all an idea: Klipsch RF-7ii (L/R) Klipsch RC-64ii (C) Klipsch RS-62ii x4 (SS/RS) Klipsch RW-12D x2 (subs) Onkyo TX-NR709 AVR Oppo BDP-103D I was hoping to keep my budget under or around $800 if possible and I would prefer NOT to go with separates due to the fact that I have a very clean setup with a very open/minimalistic look, and I don't have any more space in the console I am using that was just recently purchased. Thanks everyone, really appreciate your help! ~Cheers
  13. https://lasvegas.craigslist.org/ele/5978009102.html No affiliation but this guy is on the Emotiva forum and he let me know he is selling these. He moved into a smaller house and needs to free up some space. Seems fair
  14. 8 clean good condition functioning mid-range drivers from Klipsch TSCMs for sale. 4 working Klipsch K-55-V and 4 working K-55-M. Thinking selling as groups of 2 or more. $50 for two. I am also looking for a Jubilee type top hat if anyone has one.
  15. For sale my Klipsch Jubilees w/ K402 horns , Complete with 16ohm Faital HF200 HF drivers w/ Custom made Crites Crossovers all in great condition. $6000 plus ship These are exactly the same as Bob's Jubilees so those that have heard his can attest to how they sound. Constrained layer damping on the back side of both K402's, anyone with these big horns will benefit from doing this. Both the bass bins and horns are consecutively numbered. Located in New Mexico. I have the means to transport them to a reasonable radius maybe 5-600 miles .
  16. Downsizing my collection so this is up for sale. It's a 15" Klipsch woofer (I'm not sure which model) in a custom built box made of MDF and Walnut Veneer. It's ported and the box is pretty well made (made by a local carpenter). Has a very high WAF as well since it doesn't look crazy and has a nice wood grain on all sides. Also included to complete your setup, is a HSU Research Model 500 Amplifier. It's has 500 watts and can be configured to your unique set up with multiple hookup options. I do have the original box for this. In addition, I have the following crossover chips included: 34hz, 51hz, 75hz, and 62hz (not pictured as its installed in the amp). Bass on this setup is great. Very deep, low, musical with plenty of power to rock the whole house if you so desire. Amp alone was $500 and sub and box w/ sub could easily fetch $200. I'm selling the whole setup for $350. Due to size and weight of sub and box only local pickup in Santa Clara, CA (40 minutes south of San Francisco). It's also set up so you can come audition in my home. Message me your number if you are interested.
  17. Two floor speakers. Good condition. Both Signed. One speaker has a scratch on the top but other than that they're in great condition. I live near Dallas. They're heavy and difficult/expensive to ship but if you're within a few hours drive of Dallas I'll certainly meet you half way.I know nothing about them but I contacted a pro who said "If those are in great condition those would be worth $2000 for the pair. At least that much."If you make an offer close to that - they're yours.- Jason
  18. http://www.ebay.com/itm/klipsch-la-scala-speakers-3-/262822286721?hash=item3d316dd581:g:CkkAAOSwopRYiCMa No affiliation but a great deal for someone in Illinois!
  19. RP-450C has followings: Crossover frequency: 500Hz/1500Hz Frequency Response:58-25kHz; Does it mean: 1. Tweeter's Frequency range (1500Hz ~ 25kHz) 2. Inner 2 woofers' frequency range (500Hz ~ 1500Hz) 3. Outer 2 woofers' frequency range (58Hz ~ 500Hz) As illustrated in the attached photo. And do Voice/dialogue frequencies handled by inner woofers only ?
  20. I did a full MCACC Pro calibration after properly placing all speakers (5.1 setup), the Pioneer AV receiver detected surround sound speakers (RP-250S) as a large tower speaker ! Should I keep the setting for these surround speakers Large as calibrated or change it to Small manually? I know the RP-250S is strong and has deep bass. Need your opinions
  21. Hi, so i bought a use promedia 2.1 last night and the two satalites where placed right on top of the sub when i tested it out there so i couldnt tell whether the right channel was quiet before i bought it or after however when i came home and plugged both my phone and laptop, the sound from the right speaker comes out much quieter than the left (left speaker has the control pod). I switched the wires in the back plugging the right speaker into the left channel and then the same thing happened, left speaker works just fine and right speaker (with the control pod) is now really quiet. i can still change the volume or bass on the control pod so i assumed the right channel in the sub itself is the problem. I was just wondering if this is a common problem and if there is a quick solution to this as i have no experience with fixing electronics.
  22. I have my barely used Klipsch C-3 center channel for sale here in Greenville, SC Here is my local craigslist link with photos of the speaker. http://greenville.craigslist.org/ele/5953617294.html If you have any questions please use the email link provided on craigslist as it will get directly to me.
  23. Hi guys! this my first post on this forum; I bought 5 days back a home theater 5.1 Setup with Klipsch reference premiere speakers (RP-280F, RP450CA, RP-250S & R-115SW) and A/V receiver is Pioneer Elite SC-LX901. I am glad that I purchased Klipsch speakers; they are amazing. I never heard such a natural sound like these speakers as well as the heavy bass of the sub-woofer. I bought Pioneer SC-LX901 so that I will upgrade my home theater after one your to Dolby Atmos 5.1.4 Setup. now my only concern is Do Pioneer SC-LX901 is best choice for these speakers since these speakers required 150W while the receiver is 140 W/ch (8 ohms, 20 Hz-20 kHz, THD 0.08 %, 2ch Driven FTC) Please Advice me !
  24. My husband was a huge fan of Klipsch speakers. He passed away suddenly this past January at the age of 59. He had (and now I have) a pair of Klipsch Klipschorn Floorstanding Speakers that he has had since the 70's. We have moved those enormous speakers many, many times in our 25 years of marriage. He absolutely LOVED these speakers. Well I have to part with them (I live in an RV and am renting out our house) and need help selling them. I have no idea about pricing them except what I have seen on eBay and Amazon. They are in very good condition. I also have no idea where to market them. I live in Austin, TX and would prefer local pick up due to their weight. Any suggestions?
  25. Hello all. I am looking for advice on my sound. I have a Pioneer Elite SC-81. I am running the Klipsch Reference series from Best Buy. 28's for mains , R15 bookshelves for rear, R25 center and R12 subs. My issue is that music sounds great but I don't seem to be getting very good sounding dialog from my Dish Network from this system. Is the pioneer powerful enough ? Do I need to upgrade my center ? If so will mix matching series create any issues ? Upgrade my HDMI cables ? Thanks in advance !!!
