  1. Based on my experience with my La Scalas (@ 104 dB/watt/meter), one subwoofer from anybody a small as a K-horn, or smaller will not be capable of the output required to keep pace with K-horns/Belles/La Scalas. I could not find a maximum output on REL's website, so I can't be too sure how many Studio IIs (the biggest ones) it would take to hit 124 dB at 20 Hz, but it'll take more than one since it's power amp only puts out 300 watts. Unless, of course, the system efficiency is an astounding 100 dB/W/M. At 450 WPC, sitting in corners, and 93 dB/W/M, two VMPS Larger Subwoofers can barely do it. John
  2. I mounted my ALKs to the left of the squawker brace, like the factory crossovers. The clipped corner is close to the brace and the whole thing is a little deeper that the original. I had to make new holes in the cabinet for the screws, but that was no big deal. Wow! is clearly applicable here. John
  3. Are you sure the first 3 in not an S. Look on the edge of the cabinet near the crossover to see if it isn't stamped into the wood, too. If it is an S they are from 1977. John
  4. i don't think you have anything hooked up wrong. If the Yamaha is set to LFE you will only get sound from the sub when a DVD has a signal in the LFE channel. The rest of the time, nada. If you can tell your system has a sub in it the sub is TOO LOUD. If the Yamaha is controlling the crossover to the sub, set the sub to it's highest frequency (120?) so there's no interference from each crossover. Try to set the LFE out on the Yamaha to LFE & Sub; if it has that setting that will help. Adjust the LFE out level on the Yamaha higher and turn up the sub's volume. too. However, stop turning up when you sense a "floor" to the music. A sub is to add deep frequencies that often don't exist in most music, not to add "Boom". Boom occurs at 100 Hz or so, too high for a sub. Even with La Scalas, I have my subs set to 60 Hz. John
  5. Hey Al, Ya got a home for all 8 of those? I have a pair of K-55-Ms I'd sell/trade. John
  6. Wired1, I don't think there's anything wrong with REL subs, just that one won't have enough output to match a pair of La Scalas; maybe 2 or 4 would. The Home Jubilee will be a 2-way system where the Pro Jubilee is a 3-way system, probably for power handling. The home version will use the pro tweeter (on a different horn) over a wider bandwidth. The bass horn will be very similar to the pro version, but with a modification that appears intended to increase deep bass response. They are massive and quite handsome in mahogany. Powerful just begins to describe the sound. My ears will never be the same after hearing "The Matrix".
  7. The Type A was used on early K-horns and maybe Belles and La Scalas. I doubt it should be in your Cornwall. The other possibility is that Cornwall in much older than 1980. John
  8. Great pictures! Didn't the We 555 have 4 or 5 paths through the phase plug? How does the phase plug do whatever it does? John
  9. The correct spelling is Blose! Lots of people like them, but just set the EQ controls to "flat" and see how lousy they sound. As a rule, Blose puts the least $ content in their speakers for every $ of MSRP of any speaker manufacturer, or so I've been told. They sure sound like it to me. I wouldn't accept them as a prize in a contest. John
  10. Everybody can generate an arguement for the best configuration of drivers and crossover. I'd love to listen to a pair of Carfrae horns for a long while. The look is superb. My preference is a 2-way design for it's overall simplicity and especially the simpler crossover it *could* have. Since a 2-way La Scala is either not possible, or the tweeter would be stunningly expensive, I have 3-way speakers and am happy. John
  11. There is, of course, no best amplifier. I doubt you need more power, either. To get the sweeter, warmer sound you want look at MOSFET amps. The Parasound HCA-1500A is rated at 205 watts x 2. B&K Components makes all of their amps with MOSFETS; the ST2140 is 140w x 2 and MAY slide under $1000. B&K' ST60 is a 60 wpc stereo MOSFET amp that will be plenty of power for your RF-3s. Mondial Designs makes several good amps and some are tube/SS hybrids, you'll have to inquire about prices. What I need is a good 20 watt Class A HT amp! John
  12. 111 dB, A sub is required for 5.1. With most electronics you can set the .1 (LFE) output to subwoofer or LFE only. With LFE only, the sub will get only the special effects and will not interfer with your Fortes. The problem with this is on some movies the LFE signal is infrequent enough the sub will automatically power down. John
  13. I'm sorry to hear about your troubles. I had a very nice Good Friday. John
  14. You're where I was going until I found a second pair of La Scalas, cheaper than Heresies were going for on ebay. I have the -C7, 4 La Scalas and 2 VMPS Larger Subwoofers. I like my old Klipsch as well. John
  15. CeeDog, How "hard" is your room? Have you considered heavier drapes or a throw rug to deaden the room? John
  16. I don't recall a chuckle on this version. From the liner notes, this is supposed to be the original release of "Take Five". John
  17. Call 1-800-KLIPSCH and order a replacement woofer. John
  18. This has failed twice before .... The other thread was getting too long. I've recently discovered that Dave Brubeck's landmark 1959 recording "Time Out" has been rereleased on CD (this is the original "Take Five"). The results are fantastic! The location of the 4 musicians is perfect and rock stable. It is the best recording of a drum kit I've ever heard! Simple techniques were used, maybe only 4 mics. It's simply magic! John
  19. James, You've captured my thoughts on tube amps well. I'm sure there are exceptions, but a tube amp's predeliction to frequency response errors from the speaker's impedance is enough to keep me away. John
  20. You should take this to the Pro Media sections. They are better equipped to help you. John
  21. Every amp clips when the musical waveform exceeds the amp's capacity, so it "clips" off the peak and sends a nasty flat-topped wave to your speaker. This is certain to cause damage after a short while. A speaker cannot be damaged by too little power as long as YOU don't turn the volume knob too high and cause clipping. If you do, poof goes your tweeters. That said, most speakers are damaged by small amps that are driven into clipping. 125 wpc in NOT a small amp; you have MORE than enough power for sane home use. John
  22. I think 70 Hz sounds like an ideal crossover point for Heresies. The first prototypes were said to be solid as a brick outhoust down to 75 Hz and the production models went deeper. John
  23. The Heresy II is a Heresy with updated components. In fact yours is one of the transitional models with the HII squawker. John
  24. The neatest solution I've heard is someone here used a small piece of copper plate and a machine screw and bolt to make an adapter. One end was sized to fit into the "binding block" and the other has the screw in it to accept the cable. John
  25. You can expect most oil finishes will darken the wood some. If you want to ensure the color doesn't darken the wood (or darken it the least), you should try a clear polyurethane. It should be available in flat, satin and gloss finishes. John
