  1. Thanks. I hope to get the measurements in a couple of weeks. I am having nearly all the flooring replaced in my house next week and we are very busy unloading bookshelves and getting stuff off the floor for the crew.

Thank you Michael for having the courtesy to respond. "You need to review the entire thread. THere are dimensions for the grille, motor board with back mounting, motor board with 601 and K77 flush mounted in rabbets." I've reviewed the thread and all the drawings. No where is it explicity stated that the drawings are for the K601. No mention of K-79 tweeter. I can template from my own pair 86 CW IIs for this,and I'll be glad to post those results. I thought the aim was to have a common baseline that could be changed to reflect all known variants of the Cornwall (vertical, CW I, CW II with K600/K77 flush mounts, later CW IIs with flush K601/K79s, etc). ----------------
  3. Maybe the thread has died for lack of general interest, but I would still like to know if the dimensions of the 'final' drawing posted are for the Cornwall II with the flush mounted K601/K79 horns, or for the earlier CWI with the back mounted horns. Thanks
  4. The losses folks are taking on this overpriced "equipment de jure" are enough to buy several all-Heritage 7.1 systems!
  5. Allen was more restrained than I would have been. After the interviewer flaunted his "taste" in gear, I would have told him-on the record-to sell that overpriced dreck and buy Klipsch.
  6. Quoting Don Davis: "Home construction of this complicated device has a long history of unsatisfactory end products". If I'm going to build anything, it would be a Jubilee clone.
  7. I do think it's a spoof, albeit a very clever one
  8. http://members.aol.com/TerryR6525/ Terry is an engineer who has done some excellent radio work for me. He may know someone who could help you. Also, try Duke Lejeune at: http://www.audiokinesis.com/home/content_aboutus.htm BTW, I am a former New Orleanian and I also have CW IIs!
  9. I am looking for two more Cornwall IIs, specifically, the models with the front-mounted K601 mids and K-79 tweets. I am looking for local pickup in a triangle bounded by Baton Rouge, Atlanta, and Jacksonville. That triangle can flex, a little. My first pair were from e-bay but arrived with cab damage due to poor packing. So, pick up is really what I'd rather do this time. TIA
  10. I may have missed a post here, but are these latest drawings for the "last version" of the CW II, with the front-mounted K43 woofers, K601 and K79s?
  11. They were very expensive by contrast with other good turntables, and to my knowledge, only Pioneer and B&O made them. Somebody else made a vertical format table that vanished pretty quickly. I think Radio Shack also sold a rebranded Pioneer. The higher cost and the lack of audible difference (to most folks) made them the perfect solution to a non-problem. Garrard marketed a TT with a pivoting cart shell (the X-100 I think) that was said to achieve the same degree of tracking accuracy, but improved cassettes pretty much sealed the doom of mass-market vinyl before CDs came along.
  12. The reason you have not received any replies is that there are no hi-fi publications that are truly neutral, nor can there be so long as a magazine accepts advertisements and manufacturer's samples. About the most neutral reviewer is Consumer Reports, since they accept no advertising and buy their samples on the open market. My advice is to read any publication with skepticism and get basic technical education in electronics so you can detect the many fantasies running around out there.
  13. Interesting set of products. The keyed power switch is a little too A.R. or cutesy, (take your pick). Reminds me of the fortress listening room in "Edward Scissorhands".
  14. I agree with everything you said, save for the last part. I've heard several pie-in-the-sky omni systems that have elaborate back stories about point sources being the supposed Holy Grail of speakerdom. It's all baloney. The omnis of the 70s-remember the Design Acoustics DA-12 dodecahedrons? were mediocre speakers with cheap drivers blasting every which-a-way. Then there were the lemmings who followed the Bose 901 with cutesy designs based on crystal shapes. Live musical instruments are not point sources, and after being processed through the recording chain, recorded music is nowhere near a point source. The point source boys-among them Amar Bose-took a leap from single-frequency electromagnetic radiation in free space and tried to fit acoustics, and practical loudspeakers into it. Going back to PWK, the ideal radiation pattern of a speaker is 90 degrees uniform over every audible octave. If you have cornered, high quality speakers you are getting the closest approach to that. I add the caveat that speakers designed for very wide dispersion don't do well in corners due to early sidewall reflections. I built a pair of systems that has about 120 degree dispersion up to the 9th octave. It sounds mediocre in corners due to these reflections. That's one reason why they were replaced with Cornwall IIs.
  15. just a little tutorial here, folks...the 'crossover distortion' to which this article refers is _not_distortion arising from a speaker crossover. It is refering to the distortion produced by an amplifier when the signal 'crosses over' the zero line, going from a "positive" to a "negative" wave form and back. This was a real problem is germanium based transistor amps but with improved silicon devices is now a non-issue.

In years past, some tweeters have been made this way. There are a number of variables that make such a blanket assumption risky. Moreover, an inverted dome will strike the pole piece sooner than a "proud" dome, and decreases the amount of air trapped between the dome and the magnet, affecting Xmax and high-frequency resonances. Secondly, every speaker manufacturer wants to make his product distinctive, so, surround color, cone color, non-functional doo-dads of all types are added to make a product stand out. Inverting the dustcap is pretty much a no-cost means of making a speaker look 'different'. In sum, I would give the inversion, or non-inversion, of a dust cap ZERO weight in considering the merits of any driver.
  17. You can't compare the interface of a mouth to that of a driver on a horn. The impedence mismatch with a mouth is too great.
  18. Style B has always had the 'riser' or "collar" between the bass horn and the mid/tweet section. Look at: http://www.hifilit.com/hifilit/Klipsch/Klipsch.htm The first article has a picture from 1951 showing a style B. It has a riser and a narrow kickplate. I think the kickplate grew over the years, as a glance at the pictures from later in the 50s shows. The picture from 1951 is a personal favorite since it shows the cats enjoying the warmth coming off the receiver (a Pilot?). My old cat used to spend hours on top of my Pioneer SX-1250 which was a real 'stove'.
  19. I am considering the Samsung 30 inch HD series. If anyone has any experience with these please let me now. I have found a few opinions on the web and all are positive.
  20. Back issues of Speaker Builder (now folded into AudioXpress)have many good articles on what and what not to do.
  21. Thanks. If the K79 is 3dB less efficient than the K77, then could the stock network (whatever that maybe for a particular Khorn) be adjusted without resort to L-pads or another autoformer?
  22. I am wondering if anyone has considered retrofitting Klipschorns with K-79s. I prefer them to K-77s, and they might *just* fit. The availability of K-79s is another question of course. Another question: Is the K52/K600 combo one item that cannot be dissaembled to change the diaphram? Thanks!
  23. I have Cornwall IIs and they are fine with ANY music, rock included. One hint: keep them about 2 feet OUT of the corners (sorry Paul). They have a strong bass and corner placement makes them just too tubby. I listened to the remastered Thick As A Brick the other day and it was like being pelted with diamonds, the clarity and power brought tears to my eyes, and I am a well-seasoned audiophile.
