  1. RCA will never die. I think it's been around more than 100 years. Sadly, though, it is now just a trademark, bought and sold by various others.
  2. As a child, I remember hearing Korean war broadcasts over our Emerson. I was especially interested in the cannon [artillery] fire. Kids had plastic Bazookas that fired ping pong balls. The Emerson was open backed. When the HiFi craze started in about 1952 or so* I got my parent's permission to use the Emerson's (12"??) speaker and cabinet as the speaker as my fledgling HiFi speaker (I didn't have the real thing yet, which a few years later was a JBL D130). I moved that Emerson all around the living room. Can you guess where it sounded best? The corner. *pre-Stereo, solidly mono, except reel to reel tape, a crazy Cook double cartridge record playing system and certain movies in CinemaScope, 70mm Todd-AO, etc.
  3. My parents had an Emerson console radio, c. 1937, that looked a little like this. I think it would look good perched on top of a Klipschorn.
  4. Some people replace the glass (with double glazed, the pane that faces into the room) with thicker glass. I think our inner panes are 1/4" or more. It would be best (maybe) if the inner pane was flush with the wall, not set in, without trim that sticks out. That way, not only your realtor, but your contractor, will think you're a bit odd. We searched all over the SF Bay Area for Klipschorn ready homes, then, when we found we could no longer afford that locale, we looked around Oregon for good corners. Found them! We ended up replacing the walls of the Klipschorn room with firmer ones, anyway. This is just a guess, but I would think that obstructions along the walls with the Klipschorn corners for 4 to 6 feet out, would be more important than a little indentation of the windows.
  5. Thus the efficacy of double blind tests. Also, the variable of "brain state" [concentrating on the sound to make a judgment v.s. letting the music wash over you when you are relaxed while listening the music for its own sake for a period of time (minutes to hours to weeks)] can be built in as an additional independent variable in a 2 way ANOVA or other design.
  6. Starting in about 1957 my friends and I would use 14 gauge, copper, stranded zip cord from a hardware store. We were cautioned against using 18 gauge for anything except the shortest runs by audio magazines, sound stores, even Boys' Life (I think I remember). Just about when I was considering getting some 12 gauge (early '70s), Radio Shack introduced two lines of speaker connectors: 1) Something laughingly called "speaker wire" that was about as thin as you can imagine. perhaps 20 gauge or thinner 2) A relatively cheap imitation of Monster Cable. I ended up getting real Monster Cable, since replaced by something else the name of which I've repressed, but not expensive.
  7. Yes, if the comparison set-up isn't double blind, or at least single blind, how will anyone know that the difference isn't due to extraneous variables such as 1) the appearance of the equipment 2) the reputation of the equipment?
  8. I think it was Hi Fi Revised 1958 edition by Martin Mayer. As I remember, it was a paperback with good photos and illustrations, very clearly written and fully understandable to me as a school kid, providing some technical background and history, and presenting what Mayer thought of as the best choices at various prices, but my memory is a bit rusty when it has to reach back 63 years! It mentioned the Klipschorn (ingenious, but "too efficient" ??? -- another vague memory), JBL Altec, Marantz, McIntosh, H. H. Scott, Bozak, Leopold Stokowski, Perry Como, etc. I rediscovered the book decades later -- it had been relegated to my parents' basement and looked remarkably like the Dead Sea Scrolls, so I discarded it. It's fun to remember The Way We Were. I maintain that if 15 ips, half track stereo tape was the source, the best sound of then was about the same fidelity as now, making some "audiophile" sound in ultra snooty high end stores sound pale, dead, and un-dynamic. As the late Art Dudley put it, " ... what did we give up to gain such easy access to [the virtues of modern equipment]? Natural-sounding dynamics. Impact. Pluck. Snap. Body—especially body. And soul." Martin Mayer was a man of (popular) letters. He wrote many, many books. In the introduction to one, he stands in front of a mirror and addresses himself as Fyodor. Need I say more? Here is Amazon's offering.

  9. A few hours sounds good to me, BUT ... One Klipsch engineer, whose name I forget (not Roy) said, speaking generally, "15 minutes." I've heard other people say "30 hours," but never "400 - 500 hours." Some manufacturers do recommend very long break-in periods. I'm suspicious that they are hoping that adaptation occurs, when, despite your best intentions, and intense self examination, you are fooled into thinking speakers sound better after you are good and used to them. This might protect manufactures against negative first impressions. That being said, back in 2005 I put AK5 updates in my Klipschorns. The kit (from Klipsch) included redesigned crossover networks with very different slopes, and new midrange drivers and tweeters. Yes, they sounded a bit different, and a bit better on some program material, right away. But I burned them in with all kinds of music, at concert volume, for about 2 weeks for an average of 3 hours a day. That would be about 42 hours. So help me, they improved, sounding smother, and better in all those wacko audiophile ways, like "better integrated," etc. Placebo effect is real. I, too, eagerly await your impressions.
  10. @Chief bonehead , are you reading this? What frequency range is the passive radiator tuned to? Would it work in a room like his? What about just turning up the bass control a bit (if there is one). Thanks! As to a kick drum:
  11. It's a sacrilege. I've never tried it, but I remember a caution in the old Martin Mayer book (1958!) to not "overdamp" a speaker enclosure with too much glass wool or cotton wool. I have no idea whether this is or not. By the way, until Star Trek misused it in the series beginning in 1966 (and ever after), it was "damping," not "dampening." It is still "damping" in orthodox circles. For instance, a power amplifier doesn't have a "dampening" factor, unless it is incontinent. Given the small panels, I wouldn't expect much in the way of resonances. Did you hear resonances before stuffing it? Call me naive, but I would think PWK would have added an inexpensive item like stuffing, if it would have helped. 1983 was late in the Heresy I's history, so there would have plenty of time (26 years) to discover and remedy an inexpensive limitation. The Heresy I's were discontinued 2 years later. Weren't the midrange drivers labeled or stamped PWK in 1983? Given no stamp/label, and the huge (10 dB) elevation of the mid and tweet (before you corrected it), I can't help but wonder if they are stock Heresy, or modified by the former owner. If it were me, I'd consider leaving the stuffing in just one Heresy, take it out of the other, and AB them (with the preamp switched to mono) with rambunctious, bass heavy music, followed by pipe organ, and seeing which sounded better, while noting any resonances. Or, use a frequency sweep for the woofer only. Then, for the sake of counterbalancing to eliminate order effect, switch the wool to the other enclosure, and AB them again. Good Luck! Be Safe! 😷
  12. Location: Oregon. So far, our home relies on public power, with moving water the largest single source. Many residents (who aren't under the trees, like us) use solar. It seems like this is increasing. There are some wind farmers, who were pissed a few years ago, when the state told them they had an oversupply of electricity and it would not buy energy from them for a while.
  13. I would think that even the sealed back ones would benefit from the boundary gain of a corner. Tight in your corner, one side of each Khorn would have an 18 to 20 foot extension to the horn! You could try a very slight toe-out v.s. a snug fit. Be sure to include both conditions, with identical bass heavy music, and a test tone recording or REW (Free, but you supply a calibrated mic that is USB ready -- $80 to $100).
  14. Ah! Please let us know what you decide. Good luck!
  15. Two different posters: @angelaudio and @rankaudio To angelaudio: I once had Klipschorns just about that far apart (8 feet), and they sounded fine, to a listener sitting dead center. For others, the sound was good in all ways except imaging (but still sufficient for me at the time). Are you expecting to move to a wider room eventually? My move to a larger room (4,257 cu. ft., and wide) was richly rewarded. How high is your ceiling? See Chris A's corner horn acoustics thread. It might be possible, but outrageous, to put the Klipschorns on the long wall of your room, pressed tightly into the corners, if you can afford to put in a horn loaded center channel (Belle or La Scala I, II, or AL5). I'd say they need to be snugly in the corners, unless you build artificial corners, and you put them in those. The K77 tweeters in the Khorns are probably good enough a bit off axis (but will show some attenuation above 10K Hz), to allow you cross their aim somewhat in front of you. If not, can you put your center listening chair (or center of a couch) at 8 to 9 feet away? Don't put too much absorption in the room, but do put 2 feet of absorbers on the side and front walls where a yard stick placed flat on the front of the Khorns will touch the walls, at the height of the "top hat" of the Khorns (midrange and tweeter section), and for 2 more feet into the room. Diffusion is O.K. Showing the acoustical absorber (the lower one) in the larger room:
