  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!
