  1. he should have been looking for zero on the left hand quadrant?
  2. most speakers have a 50% profit margin. I used to be a dealer with Paradigm, Yamaha, PSB etc. Even the higher end Paradigm lines. So a MSRP $10000 Khorn costs the dealer about $5k. Having said that, most specialty dealers need about 25-30% overal profit margin to survive. So haggle all you want, but let the guy make a living OK! BTW (selling price - cost)/selling = profit margin or "points" ($100-$75)/$100 = 25% profit margin or "25 points" ($8500-$5000)/$8500= 41% profit margin. Resonable for a Khorn, but you may do better. BTW, Plasmas, LCD tvs, DLP/LCD projection used to have 25% profit margin. while tube TVs and DVD players etc had 20% margin. I would not be surprised if the 42inch TVs now area at a 20% margin because of competition. Low end digital cameras where already at the 18% rate. Sure there where some volume rebates at the end of the year, but that is what put the food on the table. I use to say that even if I sold all my TVs, DVD players, Digital Cameras, and camcorders at full list price I would still not make enough profit to survive. Thus why the expensive wire, interconnect and accessory market has emerged.
  3. having spent some time in the audio retail industry, my feeling is that Klipsch needs to be big enough and have a large enough product line to be able to be a supplier to the big box stores. Klipsch by itself is still considered a high quality, but niche brand. In order to sell larger volumes to the big boxes you need low end speakers too. I do not think that Klipsch wants to lower the brand image of the Klipsch line. Jamo is also not that well known or recognised here. So with the 3 lines, they have a broad product line to offer to big box stores and specialty stores.

  5. What do you think gang? http://www.klipsch.com/news-center/press-releases/details/klipsch-group-inc-acquires-audio-products-international.aspx This is great. Together with Jamo, it gives the Klipsch group the size and product line to compete and stay alive!
  6. The HP ac voltmeter is way overkill if all you want to do is adjust levels. All you need is an simple voltmeter that measures AC at the voltage range you want. Most PCs have audio outputs that are dead flat and with free sw can generate sine waves, and you can also burn CDs. Use this flat output to test your voltmeter vs frequency. I just tested my el cheapo 30 year old analog multimeter. The 10V ac range is flat to over 10Khz.
  7. Couple of comments: Cardio is important, but if you are getting older, it is critical that you keep up bone mass and strength. Weight training is key to this. Bowflex vs weight machine vs free weights. It comes down to personal preference. The key is that you do it. We have had a True 550 treadmill for 5 years and love it. It is long and wide and I can run and sprint up to 12 mph with no complaints. Expect to pay $2K or more for a good treadmill. Stick with name brands such as True, Precor etc. Stay away from sears. While the Nordic Track ski machines have a good reputation, their treadmills are not very reliable. Consumer reports and Runners World have good reviews. As for weights, we have a Body Solid rack with barbell as well as hex dumbell sets. Something like this: http://www.bodysolid.com/Item.aspx?ItemID=489&ItemLabel=GPR378%3a+Body-Solid+Power+Rack add accessories like an inclide decline bench, leg curl/extension etc. You can get good discounts, delivered to your house from many discount fitness web sites. BTW I am 45, and have noticed that lots of simple chores around the house are easier since I restarded fitness training 5 years ago: up/down Ladders, chopping wood, taking out the gabage... moving the LaScalas, carrying my wife to bed... I would also suggest spending some money with a personal fitness instructor just to begin with for a few sessions. You can do lots of damage with bad lifting form and posture. This is especially true if you are getting older like I am. It is easier to get injured and takes longer to recover. Start easy and build up over time.
  8. The engineers at Monster must walk around with paper bags over their heads. No respecting engineer would stand behind this bullshit. Unfortunately, unless you have taken university level courses in electromagnetics, you are in no position to refute these bogus claims. And only a small fraction of the population has this level of education.
  9. What do you want to measure? Do you want to watch meters move while listening to music and try to see what sort of peaks you get? Analog meters will never capture the very fast peaks that cause clipping unless you can already hear it, unless then have some sort of active cicruitry and leds. Or do you want to measure power duing a constant tone?
  10. 2 issues here: 1:If you could measure, what would you adjust the output voltages to? This is a real practical question! 2:Choice of equipment. For measuring voltages there are several factors in the choice of a voltmeter: 1: range: Does the voltmeter have a low enough range to measure the preamp output of under a volt, and high enough to measure the 10-50 volt output of a Power amp? 2: Will it measure RMS and at what frequency? Most simple voltmeters will rectify the AC, and then convert the resultant DC peak to RMS by dividing by sqroot of 2. This assumes that the voltage is a sine wave, AND that the circuitry has the frequency response required. Most cheap voltmeters will read 60Hz sine OK, but may not measure 1KHz or 10Khz well. You could do all your tests at 60Hz, or invest in a better quality voltmeter. More expensive voltmeters also measure "True RMS" and will correctly measure the real RMS voltage of a severely distorted signal. But this is not your case. I just went to the Radio Shack web site and the key specs are sadly lacking . 3: The last spec is what the input resisance of the voltmeter is: How much does it load the circuit. This is normally given in ohms/volt. Cheap Analog meters may have 10K-100K while electronic meters will have 1Megohm or more. For measuring preamps and power amps, this is usually not critical since these have low output resistance. So, where does this leave you: Make a CD with a 60Hz tone, full amplitude. You can find lots of places on the web to get pc sine generators that will also make .wav files to burn cds. Then get a voltmeter that has a wide enough range of say 500mv to 100volts or more to measure all the outputs you need. Most modern HiFi equipment have very flat frequency response. You could burn a CD with higher frequency tones and test the response of your voltmeter!
  11. My wife and I are in our 40s, happily maried 14 years and have 3 kids. I see so many couples with kids getting divorced. My wife tells me the woman's side, which I presume is somewhat biased, so I will only comment on what I observed from the male side of disfunctional familes near me that have divorced or are on the verge: 1: Dad works weekends (That is not his fault, he does work hard), Is off on monday and tuesday and plays golf. I never see him playing with his kids. The kids are at our house more often than at home and I play with them more than he does. He spends more time with his golf and drinking budies than with his kids.... 2: Dad plays golf all the time. Spends 20K on golf membership. His kids need clothes and his boy has ADD. Where is dad when his kids need him? They divorced years ago. 3: 2 of my 3 kids are soccer age. I work all day, and then take them to soccer to give my wife a break. Where are the rest of the dads? Surely you can make a 7:15 game once a month? 4: Met a dad at a birthday party. The week after at soccer I asked the mom where dad was... She said they where separated. Um excuse me, Separated from you maybe, but did he divorce the kids too? Where the hell is he? I see far to many men not taking the responsability to be a father or a husband. Yet I know of a couple with 4 kids who are not that well off. Both work very hard and he held down 2 jobs while going to school to change carreers, then moved the family to where the job was. I take my hat of at this guy. Conclusion: Men can be real men if they want to, but some think that they are still in college.

    HDTV Antenna

    Most of the guys who install satellite TV dishes will also do antenna installs. Call you local independantly owned audio/video/TV/Sat store and ask them who installs the sat dishes for them. Try your local yellow pages etc...
  13. Didn't many Audi drivers do that while in reverse?
  14. Telemarketing is not so bad in Canada yet. Most of our illegal immigrants are secretly plotting to blow up something in the US, they don't have time with telemarketing jobs. I guess once they cross the boarder your great Homeland Security people thwart their plans and all they can do is telemarketing...:-)
  15. Go up a link and find lots of fun stuff http://www.roger-russell.com/truth/truth.htm
  16. I do think that if/when properly done the new HD dvds will be spectacular. I also think that the real big money is lost to large scale copying and not hacking by individuals. Those who have made hundreds of copies of dvds for home use would not have gone and purchased them! I have also seen some pirated DVDs purchased in HongKong. What a laugh! These are done by someone sitting in the movie theatre with a camcorder! Does Holywood seriously think that fancy copy protection will prevent that? do you think people that buy that garbage would actually spend the $25 to buy a dvd? I think that a much better business model would be to sell DVD for $10 That way you buy it inseat of renting or pay per vue. I will not take long bofore someone in China reads off the raw data stream from a HD DVD and stamps copies, data encryption and all.. .
  17. How to perfectly reproduce an instrument: Record in an anechoic room with a spherical array of microphones placed around the instrument. Using as many independant channels as there are microphones. Then reproduce with loudspeakers placed in the same posision as the microphones? Quadrophoncs and today's 5.1 SACDs try to do this but only on a 2 dimensional basis, and the recording studio acoustics are modified by the playback studio acoustics.
  18. Lower (thicker) Gauge is not always better. Thicker wire also means thicker insulation wich separates the wires more. The capacitance of the wire decreases with separation but the inductance increases. So moving from 14 gauge to 10 gauge decreases capacitance but increases inductance. A number of tests on Audioholics shows that 12 gauge is about the best you can get. Going lower can reduce performance because of increased inductance.
  19. There is lots of info on the web. Just google tremolo vibrato, amplitude frequency modulation leslie etc. I gotta get work done, but losely speaking Tremolo is amplitude modulation and Vibrato is frequency modulation. The modulating vane probably produced mainly AM/tremolo. The Leslie speaker had a rotaing HF horn (and also a bass) that not only produced AM modulation as the source moved near and far, but had more FM/Vibrato caused by the dopler effect of moving source. My understanding that these crude mechanical systems did not produce pure AM or FM. The rotating vanes also probably produced a bit of FM due to a small dopler effect.
  20. Since when do you listen to music though the power lines in your house? A standard household A/C line has 110-120 volts of juice along with up to 15 amps of current to easily push through the little amounts of resistance created by oxidation buildup on the lines to not effect anything. The effects of oxidation buildup is much greater to an audio amplifier due to the lower voltages and amperages. This statement is not only contradicting itself but not a good comparison to support the differences. First: Power amp output can be up to 50 volts AC or more, at many amps. So this is very similar to houshold current. For example, to deliver 200 watts to an 8 ohm speaker requires 40 volts at 5 amps. This is in the ball park of household current and voltages and thus we cannot simply disregard comparisons. If we were off by a factor of a hundred then OK. Second: Higher currents require better conductors and would be more affected by oxidation than lower current speaker requirements. A very low current may be unaffected by oxidation, while a higher current will. Source voltage is not a factor at all, since it is the IR loss determined by the current and resistance of the wire/interconnect that will determine the voltage drop. Terms such as "juice" and "push thru" are meaningless in a technical discussion. Furthermore, as long as the ends have good contacts, oxidation on the surface of individual strands would not affect conductivity much as long as it is not deep. If you believe that individually insulated Litz wire is good, then individually insulated by oxidation speaker wire should be good too! And of course skin effect is not significant at audio frequencies. This has been known for a hundred years and does not need to be redundantly re-proven over and over again! According to the scientific method by which our civilization survives, it would be up to cable companies to prove that skin effect is important, not the oher way around! And with that, have a good day Chops!
  21. OH NO SKIN EFFECT IS BACK! RUN FOR THE HILLS. LOCK YOU DAUGHTERS IN THE ATTICK! SAVE YOUR SOULS! I for one, don't bat an eylid for SKIN EFFECT. A double barrel 12 Gauge takes care of SKIN EFFECT nicely. My wife and daughters are safe.
  22. Its nice and melow. The smoke (you guess what kind of leaves) is cooled by the water. I dare say that smoking pot from a ****** is hell of a lot safer than risking your life on exctasy. A 13 year old died in my town because she took something real bad.
  23. She doesn't seem to get it. Giving your bride expensive jewelry is supposed to be insurance in case you do the unthinkable and she ends up on the street. Same thing for dowaries: the bride's parents are supposed to keep them for the day that the husband no longer finds her atractive. So what is she supposed to do when you come home with the young secretary from the office? Cary the Khorns on her back to the local woman's shelter? Arg! Where is her Lawyer? She needs some advice! Didn't she insist on a pre-nuptual agreement?
  24. Glowing review! http://www.audioholics.com/productreviews/loudspeakers/KlipschUltra2Systemp1.php
  25. And the Trinidad Sweeden game was one of the best so far. So what not scoring. but what action!
