  1. This conversation reminded me: I worked in a large stockroom with tall ceilings. After enduring a cheap radio for music in the room, I told my co-workers I would bring in a "real" stereo. I brought in an old Pioneer receiver, and two cheap, single driver speakers. I hung the speakers from the overhead girders, strung roughly ten feet off the floor. The sound was airy, spacious, with not a hint of reverb. Yeah, bass was not powerful but overall I would consider the sound "full range" for what it was. I think speaker location in this case was the secret sauce.
  2. Hanging subwoofers in free space would require substantially increased power to reproduce low frequencies. From an aesthetic perspective i.e., Wife Acceptance Factor, the concept would be a non-starter. In most cases, listeners are interested in hearing sound direct from the performer i.e, nightclub or other small venue. Many performers' amps are at people height as well, as are most acoustic performances. Your concept might have some merit if audio evolved into a multi-channel configuration like home theater. Also, your concept has merit because is shows that a lot of large venue amplified sound is coming from speakers in free space. Perhaps our audio systems' speakers should all be on stands away from walls for the best reproduction.
  3. Simply Speakers sells a gasket kit for various sized woofers. Call and ask if one size will fit your passive radiator.
  4. The subwoofer driver's specifications may put limits on how high in frequency they can reproduce, independent of the cabinet they came out of or the amplifer attached to the cabinet. Therefore, they may not reproduce the same frequency range as a standard speaker's woofer, even though they may be the same size. Of course, the cabinet you re-mount the subwoofer driver in will have an effect on the speaker's performance, but most likely on the low end rather than the high end. So yes, they most likely will sound different.
  5. It's now 8PM eastern time and the ad is still up, so I'm assuming they're still for sale or the seller failed to take down the ad. There's also a $300 pair for sale in Newburgh NY.
  6. If the OP has tracking for the shipping vendor (UPS or Fedex, etc.) then perhaps he could use the "redirect" option to change the delivery address and point it back to Klipsch?
  7. Another difference is obviously the subwoofer's dedicated amplifier. Reproducing low frequencies at the required levels to match the rest of the program material whether music or movies, requires more power than a typical amp delivers. That's why subwoofer amps typically have higher output ratings than stereo amps.
  8. The subwoofer driver will have a speaker surround that permits greater excursion (say, 3/4" for a subwoofer vs. 1/2" for a typical driver although those are not real numbers). The greater travel is needed to move sufficient air at low frequencies.
  9. Today was an audio repair day for me. At work, I was servicing an intercom system for a police department. With the system, they are able to listen to the people in the cellblock, and talk back to them if necessary. The system uses a ceiling mounted speaker as both speaker AND mic. In this case, the mic/speaker was an 8" driver. After many hours of troubleshooting the electronics of a system I know little about, my colleague and I discovered the reason the dispatchers could not transmit to the cellblock was because the speaker failed as a mic, yet it worked fine for receiving audio! We replaced the 8" driver with what we had on hand, a 4" driver, and it worked wonders. So I go home tonight and decide to put on a new CD for a first listen, and I'm getting hum through the speakers. Huh? I had just reinstalled my stereo after having new carpet installed so of course everything was unplugged, moved, then plugged in again. After much troubleshooting and substitution, I found the culprit- the shield on one of the RCA cables had a broken shield connection, barely visible even with a magnifying glass! I'm gonna try to solder it together. If you look REAL closely, you can see the shield wire and the gap to the connector.
  10. You already have a subwoofer, and presumably your A/V receiver is set up to the proper crossovers to send only what's needed to the fronts with the sub taking care of the rest. I don't think you'll notice any difference worth the purchase.
  11. As long as the amp is not clipping at your listening levels, you have enough power. But if you must "match the RF7III floor standing speakers to its maximum level" then according to the specs, 250W is what you need. At 100dB efficiency, you'll hardly need half that much, let alone bi-amping the speakers.
  12. You're assuming that's an actual listening setup. Could be the photo was arranged for the ad. Don't believe everything you see.
  13. Try this to remove the adhesive sticker intact: You need: Gloves, rag, near-boiling water, plastic wrap. Soak the rag in the very hot water. Wrap in the plastic wrap. Hold against the sticker for a minute. Test for release. Reapply if necessary. You could also skip the rag and pour the water directly into a ziplock bag. Lay your speaker face-down and rest the "hot water bottle" on the sticker as above.
  14. Get the floorstanders that play as low as possible, and are within your budget. That way you'll be less inclined to crave a subwoofer, until you build your home theater. Bookshelf speakers are for people with limited budgets and room space, or for those that already have a subwoofer to pair them with. New or old model, used or new; doesn't matter. Speakers don't really change that much from model year to year in sound quality to justify getting a newer model. Dealers, and Klipsch, are trying to liquidate old inventory to make room for new, so there are good deals to be had on the Klipsch web site during the holidays but you have to act fast because inventories are usually limited. Since you only listed one bookshelf speaker, that will certainly be outperformed by the 3 floorstanders you have listed. Lastly, at some point the speaker's size aesthetically overwhelms the room. You'll have to ask yourself whether that's the case and which speaker size-wise would be visually acceptable in that room. In my case, I would not want a speaker that's so tall that it starts to block a window so I would consider height when choosing a floorstanding speaker. Let us know what you choose, and perhaps show us a picture once you get then set up!
  15. Don't believe everything your read on the internet, including this forum! If it ain't broke, don't fix it.
  16. There's a pair of HBR Heresy I's being sold on local craigslist for $600, lowered from $700, in good condition. There's also a pair of kg 1.5's that just appeared today for A reasonable $85. There ARE sane people out there.
  17. With SVS, you're comparing a sealed subwoofer vs. the Klipsch's ported design. There's a difference in sound. The SVS costs around $200 more than the Klipsch; that surely means you're getting more for your money so I think it's an unfair comparison and SVS does not have a less expensive model to fairly compare to. I've got an SVS SB-1000 (not the pro model with the remote, etc.) and it's a very compact box. To Klipsch's credit, the R-121SW is currently being offered at the cheapo price of $299 on the klipsch.com web site. For that price perhaps you can ignore a few Hertz and get the sub that looks good with your existing setup.
  18. Getting back on topic: I live in a condominium complex; 300 units, I think 300 acres. Excellent east/west roof exposure. Lower middle class to middle class demographic. Problem is, condo owners don't own the outside of the structure, so we can't install solar on our individual units. For the association to install solar on all the units would be a tremendous financial undertaking, including special assessments much like the $8k I paid when roofs were replaced. People moaned at those costs; I imagine solar conversion would be much more expensive. But as a whole, I wonder whether the association would be a net producer of electricity with the result being a worthwhile payback. Something tells me solar isn't providing returns attractive enough for even our association to consider it, let alone if individual owners, and homeowners in general, to benefit. Discuss.
  19. If you read this current article in The New Yorker Magazine regarding the renovations of Geffen Hall, you'll begin to realize it's your room's acoustics that are more important than your components.
  20. While I have nothing to add, I will say thanks to the OP for posting his self-discovered solution.
  21. Are the THX speakers connected directly to the subwoofer or to your AV receiver? So your "2.1 THX speakers and sub" means your system was purchased as a package (the speakers and sub came together)? Can you show us a photo of how you've connected the speakers and the sub?
  22. I listen to mostly FM radio, and lower powered stations (88-92MHz). While I live in a reasonable location with several stations to choose from, the signal strength can vary for many reasons. And since I live in a condo, an outside antenna is out of the question. I've gotten to a point where I can get a reasonably strong signal, through the use of a tunable indoor antenna (the B.I.C. Beam Box), and an FM tuner with a switchable IF filter (Yamaha). About six months ago I was working at a high rise apartment complex when I spied an old, no longer used, Channel Master TV signal amplifier for the distributed TV signal from the days before cable TV. I also noticed it had an FM "trap" or notch filter which led me to believe I could use one to improve my FM reception. I asked the customer if I could have it but they never got back to me. So I searched eBay thinking that's the only place I'd find such a "vintage" item. Well, I could even find NEW ones! So I bought one. For twenty-five bucks I figured if it didn't work it wouldn't be a huge loss. I'll be damned; it works great! I adjusted the gain so I wouldn't saturate the front end on any station by adjusting the Gain knob so signal strength is just shy of full-scale. The only drawback was I had to use a screwdriver because the knob is almost impossible to grasp; some models don't appear to have that quirk. But I still was curious; could I improve the signal even more? Down the rabbit hole I went. I discovered Magnum Dynalab sold the MD-205 Signal Sleuth FM Amplifier. This is the Cadillac of the FM amp above. But it costs $500! I couldn't bring myself to spend that much. After a period of time while searching eBay I found one for sale but the price was about $300. Better but a little bit too rich for my tastes, and I didn't know if it would work, whether new or used. So I forgot about the idea. Until last week. Seems Magnum Dynalab made a similar product years ago under the Magnum label called the FM Power Sleuth. Slightly different name; would it work the same? The form factor was not the rack/stackable shape of the new model, but I imagined the guts had to be similar. Again, I found it on eBay but this older unit was going for a paltry less than $100 shipped. I didn't have to think twice about this one! Other than the non-stack friendly shape, it's fine. The knobs turn silky smooth and better than the cheapo version I earlier owned, the tuning dial only amplifies the frequency of interest. F-connectors on the back, and an AC cord. I get a minimum 30% increase in signal strength even with the gain set where you see in the photo. For all you FM junkies out there, if you have reception issues, this is the ticket. In fact, even the budget ASKA model above works great, just get a similar brand with a gain knob you can grasp with your fingers but honestly, I've mostly "set and forgotten" it, and it still does the job.
  23. RCA speaker cables? That's a new one for me. 😉 Yeah, I agree with wuzzzer; any RCA cable should do. No need to spend big bucks, and you don't need to consider the ohm rating of the sub. Most important is having cables long enough. If you're using the LFE output or subwoofer output of your receiver, etc., then you'll only need one cable and not the stereo pair. That should save you a few bucks.
  24. Were old Cornwall woofer surrounds subject to decay? I've never heard it mentioned before. I thought only foam surrounds had that problem, maybe rubber surrounds.
