  1. Crossover failures are rare. However, I can't tell what you are measuring from your description. Disconnect the tweeter wires from the crossover and measure the resistance across each wire. A good tweeter will read about 6 ohms and you will hear a tinny scratching from the tweeter while touching the meter leads to the tweeter leads. High resistance and no scratching means a blown tweeter. Take it to a GOOD pro audio shop and have them install E-V T-35 diaphragms at $21 each plus labor (the K-77 IS a T-35). John (w/ 4 La Scalas in my HT)
  2. Paul, I don't think you'll hear the difference between the 16 ga. and 12 ga. on your surrounds. I think the biggest factor id the limited frequency response of surround speakers and the information sent to them in a *typical* movie. Two 16s would be as good as one 12, but not a "clean". John
  3. You'd have quite a manufacturing facility if you could replace magnets and voice coils with the precision required in a speaker. If you think they are that deficient, don't buy them. John
  4. Actually, ELVIS is The King! John
  5. If you run left and right to the same, normal speaker your amp will protest and might blow a fuse, if you're lucky. John
  6. The top of the Belle DID have at least two 2x4 braces, one on each side of the squawker to support the top. I can't remember if there was a steel plate to shield the TV. Contact Trey Cannon at 1-800-KLIPSCH. John
  7. The Heritage Series are the original Klipsch speakers. They use exponential horns. The tractrix horn design has been around a long time, but Klipsch began using it relatively recently. You will have to special order the Heritage Series and it will be a while before they are in production again due to the drivers being unavailable. The replacements have not yet been selected. John
  8. RMinten, The Reference Series are 2-way systems with the midrange frequencies split between the woofer and the tweeter. I'd say the woofer reproduces the most of the midrange. The Legend series has to have the midrange horn because their tweeter cannot reproduce the midrange. Neither the Legend nor the Reference series speakers have "subwoofers", just "woofers". A powered subwoofer usually has a built-in crossover that could be used to limit the deep bass sent to the speaker. I would not recommend modifying the speaker's crossover network to reduce the deep bass. John
  9. The only "mode" I like in my ACT-3 is "Party". All 6 channels are sent a full range signal, either L, R or L+R. With Live recordings, the effect is of sitting in the middle of the Venue. The "Club" mode is O.K.; the rest are too odd sounding. For the most part, I don't use use the DSP modes. John
  10. If your horns distorted like a bad connection, I'll bet they were bottoming out in their magnet structure. A popping or crackling sound will result. I'd back off the gain about 10 dB. John
  11. You don't say what you're trying to correct, so It's hard to recommend a particular amp. However, I have a Parasound HCA-1000A that fits your bill and will have high damping to control the speaker, especially in the bass. It runs in Class A up to about 1.6 watts. John
  12. K-horns and La Scalas will sound remarkably alike until you hear a bass drum or deep bass note. Then, the K-horns will move your pants legs. La Scalas can't. I have 4 La Scalas and no proper corners. John
  13. The difference is the Promedias and Quintets are not similar in performance. From comments BobG has made, I infer the Quintets are capable of going louder and are suitable for the distances found in small rooms. The Promedias are intended for close listening and aparently cannot get as loud as the Quintets, or handle as much power. John This message has been edited by John Albright on 07-15-2001 at 12:36 PM
  14. I've seen that picture before. Now that I know more, I wonder if the horn is long enough to be a real subwoofer. John
  15. Jim, DON'T toss out those K-77-Ms! They can be overhauled at a good sound shop. The diaphragm is about $22 from E-V and is still available. Klipsch will overhaul them for about $77 each, I believe. NOS E-V tweeters may be obtained from Layne Audio in Nashville, TN (of course) for about $110 http://www.speakersupply.com/ Sam at Techstar in Nashville will overhaul your tweeters and ship them back to you for a reasonable price. John
  16. Well, I hope the plastic IS cheaper. A basic tenent of engineering is that the geometry of an object (length, width, & thickness) controls its stiffness. If the material is the same, this is easy to see: a 2x4 is stiffer than a yardstick. The glass reinforced plastic frames may well be stiffer and maintain better alignment than a equal stamped steel frame. As with the floors of your house, strength is not an issue, stiffness is. You don't want your floor to feel like a trampoline and you want the stiffest woofer basket you can afford. Good engineering is the CHEAPEST full performance solution.

  17. Socks are fine and there will be no damage to the speaker. One of my previous speaker systems (Marantz) even suggested stuffing the port to control the bass in problem rooms and they provided a response curve with the port stuffed. I have done it to other ported speakers as well. John
  18. T-man, Tell your dad, I'm doing just as you suggest. I run from the sub out of my pre-amp/processor to the line in of a seperate power amp and then to 2 huge passive subs. It works so well I routinely vibrate knick-knacks off of the furniture upstairs. John
  19. There is really no such thing as a high-end cable company that doesn't overcharge for their products. The really high-end cables have much more mark-up and therefore less value than Monster products. Klipsch chose Monster because that have been using Monster wire for several years in the Heritage Line. John
  20. Steve, Just have somebody OH that -V. You shouldn't need a new driver at all. John
  21. Connect the LFE out to the Sub. LFE is not the same as low bass in the main channels. My Pre/Pro can send the LFE signal to the mains if I want it to, but I'm not sure all receivers can. To get the best "impact" from DVDs you need that LFE connection. John
  22. First, I'd center everything on the TV screen, so sounds in the center sound like they are coming from the TV. As for surrounds, I liked the SS-1s I heard and they would not be too big to replace your current rears. Due to space, I'd look at the smaller WDST surrounds for your room. John
  23. I pretty sure "S" means 1977. John
  24. My experience with speaker cables, including Monster and hand braided CAT-5, is that above 14 guage, for 10 or 15 foot runs, there is no difference. I believe Monster Cable is 12 ga. OTOH, I have been able to hear an improvement between good and very good interconnects, but the difference was small. I define good at about $20 a pair vs. very good at about $80 a pair (I have only 1 pair at $80). The small difference may even be due to the interaction between my preamp and power amp and might not be audible on your equipment. My recommendation is to buy the best interconnects and cables you're willing to afford and later try some better ones if you just can't stand not knowing if there is a difference. John
  25. You're looking at a Heritage speaker with a letter code for the date. If I'm not in error, S = 1977. That should be a good year for Heresies. John
