  1. Driving along the road I noticed two bug black boxes sitting on a footpath just off the road. They'd been put out for a hard rubbish collection with other offs and ends. I was very curious. They looked an odd size for a floor standing speaker, but definitely some kind of speaker. So I turn around and drove back to take a look. These were a large black speaker box with cloth grills intact. I got out of my car to take a closer look. Klipsch. Apart from some minor chipped edges these looked ok. I pull off the covers and everything looked sweet. So I picked up these heavy buggers and stuck them into my back of my vehicle. When I arrived home late in the day I pulled the speakers out of my car and plugged them into my little Marantz amp. Wow!!! They sounded sweet. So I've dug around and found that I am now the owner if a pumping set of Chorus ii speakers. So things have rapidly progressed. I've picked up an Onkyo Integra a-8067. The place is pumping now!!! What are the chances, such a fantastic find. I am stoked.

  4. Good morning. It's Friday. Opening day at Comerica Park in Detroit. There's snow on cars and a forecast of 40s at 1pm game time with precipitation after 4pm. Whether the weather cooperates, we'll have a good time. We're dressed for a football game. I dug out some thermal underwear. I look like a cross between the Pillsbury Dough Boy and a waffle. Our new to Detroit starter, Jordan Zimmerman, grew up on a farm in Wisconsin. The cold won't bother him. I'll try to post a photo from our seats. Go Tigers, beat the Yankees.

  8. Morning all... Yessssss............it's Friday.............I don't what the hell that means, cuz I'm working at the shop all the time...... but I like Fridays and it's not like I get paid every Friday. The BOSS makes me sign a check once a month. Then she just take the check It's my moms birthday today. We will be going out for dinner tonight. Not a whole lot going on at the shop today.... Got a few cars to work on for the used car maggots. So it'll be an early day.... I will get the Pilot in the shop before I leave tonight... gonna start putting it back together. Will be picking the cylinder heads up from the machine shop this morning. OK.... Check-in later..... A good Friday to all MKP :-)

  11. Happy Friday All, Well its supposed to rain on and off all weekend here in sunny southern California. Time to get some inside chores done. Leaky shower valve to replace, leaky kitchen faucet also needs replacing. Hope I can get a least one of these tasks done without breaking 10 other things. Hard water sucks! Plumbing sucks! Took my wife to the airport yesterday, she's off to see and take care of her Mom in Peru. MIL is still not back to normal after her fall last June. On the brighter side I picked up a third RSW-15 on the way back from the airport. Perhaps I can also get that puppy cleaned up and into the house this weekend. Cheers

  13. At the moment I've got a half-width (15" wide) Tuba HT subwoofer loaded with a 12" driver (Dayton DVC 310-88). Corner-loaded and using a Radio Shack SPL meter set to "C weighting / slow" with a 20 Hz test tone from the Bink CD, the unit measures 100 dB SPL on 2.87V at 6" from the mouth. I also measured what voltage it took to maintain 100 dB SPL, one meter into my room.

  19. Since you bring up PWK, could you tell me some of the SET amps he used? Or for that matter any tube amps that he used later in his life when SS became a viable option to the tubes? Forgive my ignorance but I am only aware of his early favorite (modded Brooks 12A 2A3 PP of 10W. or so), and latter the various pro SS amps from Crown, BGW, etc. I think we have somehow created our own “red herrings” that we are now chasing upstream. In many of the articles where we have jumped to conclusions that Paul was promoting one type of amplifier topology over another, our conclusions appear to be incorrect and he is really expounding upon how well-engineered his Klipshorn speakers are. When it comes to amplifiers, I believe that PWK was primarily pointing out a simple mathematical relationship and facing an economic reality of the times he lived. After reviewing a multitude of evidence for which I have outlined a few key points in more detail below, I tend to hold the view that I don't think PWK can be used as an advocate of low powered SET amplifiers any more than he can be used as an advocate for mid-power solid state amplifiers. Although, in one of the “Dope From Hope articles” he does state that “In a typical living room or small theater, our present all-horn systems offer concert-hall levels with a mere 10 watts peak input.” There again, PWK specifically stated 10 watts, not 5 watts, and I believe his statement was a tribute to the engineering of the loudspeaker in that it could reproduce concert-level SPL with fairly low power (e.g., doing the math), not an endorsement of any specific amplifiers or amplifier topologies. The simple fact of the matter was, is, and always will be, the Klipschorn speaker efficiency allows a person to use very low-powered amplifiers if that type of amplifier meets that person’s listening requirements, regardless of whether that choice is SET, SEP, Push-Pull, solid state, or otherwise; and as I have noted in other posts, the Klipschhorn will reveal very quickly if the amplifier sucks or the source sucks or both suck. After spending a very substantial amount of time revisiting the “Dope From Hope” articles and various other documentation (including the pages of “Klipschisms, quotes and anecdotes" attributed to PWK on the main website), I also could not substantiate that PWK explicitly voiced, or had written the quote often attributed to him that "What this country needs is a good 5 watt amplifier." Without specific credible evidence, especially given that PWK was looking for concert-level reproduction of 115dB SPL at the listening position, I'm now wondering if the quote is a type of urban legend that has proliferated over the internet, similar to the Robert Hartley situation I describe below (e.g., in PWKs situation outlined below, 5 acoustic watts = 20 amplifier watts, not 5 amplifier watts). Jim Hunter, just where are you when we need you? Since the written records appear to clearly show that PWK loved his push-pull 10 watt per channel Brook 12A amplifier, he may have actually been complaining that amplifiers of his time were not powerful enough, in addition to not being good enough. The written information appears to show that, in addition to PWK liking the Brook 12A amplifier at first, he then moved to a variety of mostly solid state amplifiers in the range of approximately 60 watts per channel. I have also found references where he used a lot of different brands including Crown (D60) and BGW (model 100). An interesting side note with the Klipschorn history in relation to the Brook amplifier is that Paul (and Brook) collaborated to squeeze more [power] from the 12A amplifier (a 2A3 push pull design) and developed modifications to address some bass deficiencies that were revealed by the Klipschorn speakers. The modification subsequently became a factory mod available to optimize the amplifier to the Klipshorn and was given the catalogue number of “12A3-KI.” I have also found that there are many other references in his literature where he recommended 20 watts per channel amplifiers as a minimum for Klipschorns. Keeping in mind that one goal that PWK had often articulated in both verbal and written form, was that his loudspeakers were capable of reproducing concert-level sound of about 115dB at the listener's position, and here is one such reference from the "Dope From Hope" Vol. 14, No. 2 May 1974 titled "Power Ratings." "[''What size amplifier shall I buy?" This is really the first of two questions. The answer, applied to KLIPSCH speakers, would be a maximum of 100 watts (sine wave rating) per side. If a higher power is used, precautions may be needed to prevent speaker damage. Crown suggests a one ampere fuse for each channel. The second question, I think we can assume, is fishing for a realistic relation between sound pressure level and amplifier power. Accept the figure that 115 dB peak sound level pressure at the listener's ear will be as loud as what you would hear at a live concert. (A sound level meter would read 103 dB at "maximum" swings, because a V.U. meter has a "delay" or "lag", and instantaneous peaks are about 13 dB higher than the meter reading peaks). In a typical 4000 cubic foot listening room, this requires 40 peak amplifier watts to feed a group of high efficiency loudspeakers: assuming this to be 2-channel stereo, 20 peak watts per channel or 10 watts average sine wave power rating per side is required. For a low efficiency speaker (of the typical so-called air suspension type) over 100 times as much amplifier power would be necessary: that makes over one kilowatt of sine-wave rated power for each channel.]" In the "Dope From Hope" (Vol. 8, No. 1 July 11, 1967) article titled "Guarantee Void" PWK stated that, "[back in the good old days of 10 and 20 watt amplifiers it was uncommon to experience loudspeaker failures. When 75 watts became common, occasional tweeter failures began to occur. Then with the advent of large solid-state amplifiers with their 240 instantaneous power peaks, tweeter failures became epidemic and woofers began to come apart at the compliance rings and voice coils began to tear loose from cones.]" Another misnomer that I found was that PWK often referred to “acoustic watts” and invariably magazine writers (e.g., Robert Hartley), among others would drop the “acoustic” and just state watts, which was misleading and only perpetuated inaccuracies. The following are PWK definitions published in the "Dope From Hope" (Vo. 9, No. 2 June 1973) article titled "Definitions." WATT First of all a watt is a unit of power or rate of doing work, whether electrical, mechanical, thermal or acoustic. Equivalents are 0.738 foot pounds per second, 0.238 calories per second, or w = e^2/z Where w is watt, e^2 is electrical pressure or electromotive force in volts and z is electrical impedance in ohms. The acoustic watt may be similarly expressed in terms of acoustic sound pressure p in dynes per square centimeter and the acoustic impedance of air which has been derived as the product of the air density times the velocity of sound p thus w = p^2/z. When the sound pressure level is 100 dB, the sound power transmitted is 10^6 watt per square centimeter. (The 100 dB level is referred to zero dB = 0.000204 dynes per square centimeter: thus 100 dB = 20.4 dynes per square centimeter). ACOUSTIC WATT Translating the above numbers into something quickly useful, it turns out that a sound source radiating from a trihedral corner with a uniform polar pattern will be radiating one watt of power when the sound pressure measured at 4 feet is 118 decibels. Essentially, it came down to PWK’s literature recommending 20 watt amplifiers as the minimum for Klipschorn loudspeakers to meet his Klipschorn design goal of producing concert-level sound of 115dB SPL at the listener position. In my reference to Robert Hartley, I’m referring to excerpts from his book titled, "the Complete Guide to High-End Audio" where the excerpt can also be found in the article "How Much Amplifier Power Do You Need" where he writes that “loudspeaker pioneer Paul Klipsch conducted a demonstration of live vs. reproduced sound with a symphony orchestra and his Klipschorn loudspeakers. His amplifier power: 5W. The Klipschorns are so sensitive (an astounding 105dB SPL, 1W/1m) that they will produce very high volumes with very little amplifier power. Klipsch was attempting to show that his loudspeakers could closely mimic the tonal quality and loudness of a full symphony orchestra.” If anyone has been following the various posts in the “high power amplifier” thread, I would have a hard time believing that someone could still conclude that a 5 watt amplifier would attain that type of concert level SPL in a theater where a symphony orchestra was playing. The reference indicates that PWK talks about a symphony orchestra and 5 watts; however, he is not talking about a nominal 5 watts. I believe that PWK is actually talking about 5 "acoustic watts" as he has defined an acoustic watt in the Dope From Hope that I have excerpted above. Note that PWK has also put into print, including references in the Dope From Hope, a 20 watt per channel amplifier is suggested for full live symphonic dynamics (e.g., 115 dB at the listening position). To achieve the 5 acoustic watts in the room that PWK is talking about, he had two Klipschorns and a Belle with each channel connected to 20 watt amplifiers. Once I crunched the math considering the definitions in the "Dope From Hope" (Vo. 9, No. 2 June 1973) for an acoustic watt, it became pretty obvious what happened in that I suspect that Hartley may not have understood the concept of an acoustic watt or just dropped the word "acoustic" in his text. Essentially, there you have it in that it seems that PWK has outlined various situations that appear to indicate that for 2-channel stereo, 20 peak watts per channel or 10 watts average sine wave power would cover the concert level SPL THAT he had personally strived to achieve.

  28. Didn't realize this was still here, left over from the old forum...an old measurement of a SE/ss bi-amp setup. Sure looks to me like room modes are of far greater concern than any tube amp misbehavior (although those harmonics definitely do result in subtle tonal colorations). I'm sure PWK would ridicule this discussion, I can see him asking if we intend to play our records as though they were guitars, but it's his own fault for giving us the speakers amenable to such ridiculous (as well as fun and educational) approaches in the first place. If I didn't own Klipsch speakers first, I would never have gone down the tube rabbit hole. DIY, do it inexpensively, have fun with it. (Not trying to be preachy with that, just sharing experience to help 2B and whoever else navigate the terrain and avoid the puddles.)

  39. Trading RF-7's for in-wall speakers??? Go listen to a pair of in-wall speakers and if that doesn't convince you of your mistake, then check yourself into the nearest mental health facility. I'm sorry but a few a few square feet of floor space isn't worth that trade.

  40. Update... Atmos is up and running with all 4 ceiling JBLs. I just got my 2 signs for the HT back from a friend who made the frames for me. They came out great but one of them got scratched. When I order more signs for other components I will most likely order a replacement for the DTS-X one.
