  1. Wow! I just looked at the price ... almost $8000.00 for a pair plus shipping!

    For that kind of money, I want the real thing, no Xerox copies. I must admit though, like Xerox machines, duplicates sometimes look better [and work better] than originals.

    PWK's quote of John Ruskin applied to the Speakerlab copy, it doesn't apply to Vittoras.

    It's also interesting to note the Dope from Hope article in which PWK quoted Ruskin, also refers to the fiberglass squawker and fiberboard construction of the X (Speakerlab) speaker in a pejorative way. Fast forward; Klipschorn squawkers are made from composites and La Scalas are made of fiberboard.

    Be careful of absolutes.

  2. Thanks for the advice. We will keep the same window treatments as in the photo (Roman shades).

    Good move keeping the Roman shades. Vertical blinds are the perfect product if you want to recreate the classy ambience of the DMV or a Dollar Store.

    I doubt you'd be able to notice a difference between the Roman shades and plasic vertical blinds. I'd try them well sealed into the corners along the long wall before trying a center channel or false corners. It would be interesting to see if there's a difference between when the shades are up or down.

  3. for $60 i'll drive to your house and press copy to external hard drive for you....

    Will you do it within seconds of creating or changing a file and save it to an off-site location to avoid fire, flood, etc.? Also, Carbonite doesn't ask for a drink or to use the restroom.[:)]
  4. Hapy Burthday.

    We'd lose many valuable contributors if we got hung up on spelling. Al K. couldn't spell at gunpoint, but he knew filters. Unfortunately, his diplomatic skills were no match for his filter knowledge.

  5. Pedaling your wares of ripped off designs consisting of PWK's cabinets, ALK inspired crossovers, and Martinelli knock off horns and then having your minions post glowing reviews on the klipsch site...

    PWK was aware of Stenger's patent (granted in 1932) when the La Scala loudspeaker was designed. He learned from previous patents and taught in his. While ALK was not the first to use tapped autotransformers in crossovers (and I am not aware of any ALK patents), he clearly learned from previous work on RF filter design and considered both amplitude and impedance. His free disclosure of his designs is a valuable service to all DIYers who lack his knowledge and understanding. Paul Voigt used the tractrix design in the 1930's. Following Voigt's death in 1981, Bruce Edgar wrote about the tractrix design that was clearly learned by Martinelli.

    I own ALK universal crossovers and I have Martinelli 1" throat tractrix horns; while it is obvious that Greg learned from those designs, or the designs that preceeded them, Greg has made changes that may be of interest to the readers of this forum. "Ripped off" would be approptriate only if you have identified patent or trademark infringement. Other knowledge in the public domain is free for anyone to use.

    Discussion of competitor products on the Klipsch forum provides Klipsch free market research related to their product lines. When there is considerable interest in a modification or competing product, Klipsch (or the current owner) can use to update their designs and/or offer new products. The discussions here of both strengths and weaknesses would also be useful in future planning.

    [Y] Well stated. Conclusive proof that Jubilees don't cause brain damage.
  6. After I got them home it became clear that the person that performed the upgrades on the speakers had no idea what he was doing... All of the hardware was replaced with cheesy brass screws, most of which were of incorrect size and didn't grip the holes. I'm surprised the tweeters didn't fall out during the trip home. The Fastrac horns didn't have L brackets supporting them either.

    And then I opened the woofer chamber. Both speakers had their woofers loosely held in by two brass wood screws instead of the 10x24 machine screws. One woofer was loose in the doghouse, the other wasn't flat against the slot board. The installer made new screw holes next to the existing hardware, and only started to grind one side of the woofer baskets.

    The lesson to be learned here is that it makes sense to check such things on any vintage speaker, especially ones that have been modified.

    Even Klipsch employees have been known to make mistakes. I've seen drivers wired out of phase, steel screws attaching inductors, etc. It's no secret that PWK engineered and manufactured to meet a market price.

    Hobbyists are not so constrained. For example, while it makes economic and marketing sense to use only 4 T-nuts and machine screws to attach a La Scala woofer, the hobbyist is well advised to go for redundancy. The woofer has 8 mounting holes. The same can be said regarding back mounted versus flush mounted horns. To PWK, flush mounting, "doesn't make a dime's worth of difference," but it cost much more than a dime, so it didn't happen.

    It's surprising that someone would have the interest in the upgrades, but lack the fundamental knowledge to install them properly. Admit it, you would have taken them apart regardless. Now you can enjoy them with the knowledge that you made a good thing better.

  7. Carbonbite. Less than $60/year.

    Carbon Bite? Fruedian slip? :)

    Possibly. I hadn't noticed the typo. I hate it when someone says, "Your slip is showing."[;)]

    Carbonite backs up on the fly in the background. I've been pleased with it, but I've not yet tried to recover any backed-up files.

  8. . . . you probably think this [thread] is about you.”

    There are—and were—several prolific contributors to this forum who perceive any difference of opinion as a personal attack. Some feel disrespected if their recommendations or opinions are not accepted by other forum members as gospel.

    Feeling disrespected under those circumstances is unfortunate enough, but the problem is exacerbated when the aggrieved "experts" feel compelled to personally attack those with whom they disagree. It’s especially troubling when relatively new members are called names or criticized.

    A few such members have ultimately been banned from this forum, which resulted in a terrible loss of valuable resources to the forum. Others have drifted away voluntarily.

    Unfortunately, several forum members fit this description, therefore, this observation is not directed at any one individual, but if you feel it’s directed at you, it probably is, because . . . you’re so vain . . .

    Feel free to disagree, but please keep it civil.

  9. I think that I'll stand by what is written...I think most people will find it useful...(maybe not everyone...)

    Big Smile

    As well you should. I find it interesting as well as useful.

    It's counterintuitive. Most people incorrectly assume that the big Klipschorns require more power than my small BBC LS3/5As, when, in fact, the opposite is true.

    The LS3/5As are excellent speakers for their intended use as mobile monitors. A premium was placed on a compact foot print. Nonetheless, they require a prodigious amount of power to prouduce limited bass and limited dynamic range and increased distortion, as compared to Khorns, but Khorns would be miserable as mobile monitors.

  10. Many years have gone by. The esteemed mdeneen has retired, lynnm has passed to the listening room in the sky, Marvel is recently married and Craig now has sewer problems. The Sovtek 7199s were indeed the problem. Unless others have had more recent positive experiences with Sovtek, I'd avoid them.

    It is fun to show the boxes with the hammer and sickle to friends.

  11. People who know how to spell velocity have determined that fatalities can and have occurred from guns fired into the air.

    http://www.straightdope.com/columns/read/1199/can-a-bullet-fired-into-the-air-kill-someone-when-it-comes-down

    Can a bullet fired into the air kill someone when it comes down?

    “Experiments on cadavers and such have shown, for example, that a .38 caliber revolver bullet will perforate the skin and lodge in the underlying tissue at 191 feet per second and that triple-ought buckshot will do so at 213 feet per second.”

    “For the first time ever, they deemed this one busted, plausible, and confirmed. All of their tests, from the pig's head to the 9mm firing to the balloon, showed that a bullet fired perfectly straight up into the air is not lethal. However, it is also very difficult to shoot perfectly straight up into the air and, with the cases cited by Dr. Mohler, they have confirmed that people have died from bullets falling from the sky.”
