  1. The Yamaha SP 2060 has two direct digital AES/EBU inputs, . Not sure about the others I recommended.
  2. Look at the used market for EV DX-38, EV DC-1, Yamaha SP 2060, Xilica, or Ashly Protea processors. They turn up around that price from time to time.
  3. Since the Khorn woofer is about 4 feet out of phase (greater than one wavelength) with the mid at crossover, along with the aforementioned crossover phase shifts which push the woofer even further out of phase with the mid horn, it's no wonder changing the woofer's electrical polarity yields little audible difference. Phase shifts greater than 1/4 wavelength do not allow for coherent summation of the woofer and mid horn outputs. The arrival times from each driver within the speaker need to be the same before polarity differences between the drivers can be consistently heard.
  4. They are screwed to the bass bin from the top, It's been a while but there are 4 screws, IIRC. Look inside the top hat for the screws that hold the tops down. I finished a decorator model and used wing nuts to secure my top hats.
  5. A long as you don't play full blast you will be OK with the 30V supply. What speaker are you using?
  6. What are you going to do about the mid-woofer alignment?
  7. 50 cent speaks .
  8. Print media is declining for sure. This may be a good thing, as most of the surviving audio magazines are of dubious value. Stereophile is about the best if the survivors, The Absolute Sound is about the worst. I would not consider any current consumer audio publication trustworthy, as the equipment reviews are opinion pieces, influenced by advertising dollars and freebies from the manufacturers.
  9. I believe most audio enthusiasts would achieve much better results spending $400 on some room treatments than wasting that money on a freaking fuse. Audiophile fuses, cable elevators and magic rocks, along with a lot of other silly stuff, are a total waste of money. Lots of ignorance in audio, and PWK warned of this sort of thing about 50 years ago. I would like to see what he would say about audiophile fuses. I'll bet on the bullshit button getting flashed.
  10. 240 V house power is single phase, so no alternating pulses. I would run one 10 ga. extension, wired conventionally, and plug both amps into that. The current draw will be low because of the transient nature of music, should sound good.
  11. FIRs can do many functions "at once". Amplitude and phase response can be adjusted independently, crossover points, EQ, delays and other adjustments can be written into one program. The tradeoff is pre-ringing on impulse response measurements. There are techniques for minimizing these artifacts. Here is a company that sells a program for writing FIRs:
  12. This looks like a shell similar to the ones Electrovoice made for the Georgian horn, except made to resemble the factory Khorn. The factory Khorns that look like that are two pieces and the top hat is removable. What you have is not a Klipsch product, though it may have been made by someone to fit a decorator series Khorn. Most people who dress up a decorator series Khorn would veneer and edge band the bass horn then build and veneer the top hat.
  13. Electrolytics will dry out eventually, other types will last longer. On a 1980 piece I would change all of the electrolytics first then power the unit up and check to see if it is within specs. Do other repairs as necessary.
  14. Seven time Grammy winner Al Jarreau died at the age of 76 today. Sad news to hear. RIP.
  15. The trend is your friend.
