  1. The K-77-M is substantially more durable with a 10w cont. rating. In a home setting they are not at much risk so you can defeat the KLiP diodes. I would not recommend that for Pro Audio.
  2. Yes, it was. The bulb and resistor form an L-pad (~1 dB, maybe 1.5] until the bulb heats and its resistance rises.
  3. Nice find! If you keep them, you'll want them on the floor and just a few inches off the wall or corner to get better bass from them. You can expect them to need several days for the woofers to loosten up and make full bass output. Ultimately, you may want a subwoofer, too. Many of us do.
  4. I heartily agree with Dean. I've had them and the Type AL is a miserable crossover.
  5. I have one and I don't know how you'd do it. My phones, etc, won't pair to 2 devices at once and have no provision to separate channels. It does have an aux input, so you might be able to make cables to send each channel to different Grooves.
  6. An H IV will be a better tonal match than anything else short of a 3rd CW III. I use a Heresy between my 2 La Scalas. I modified the crossover to be as similar to the LA Scala crossover as practical. It much like the HIP's crossover.
  7. Yes. If you send a forum PM, the recipient gets an email notice. That worked this time.
  8. I do not remember that lamp. All along I thought I was copying dtr20!
  9. There were probably more raw birch Heresy Is made that any other. Since the "finished" H Is are also made from plywood, there should be no difference in sound. MDF cabinets may not be as strong as plywood, but are strong enough and non-resonant. Better to buy the sound you like in the condition you want and ignore the material.
  10. A 2.5A fast blow will be fine and will limit the total power to about 100 watts. Outside of pro audio, they don't need it.
  11. I contacted Gil via PM through the forum. While I have an email address, he hasn't answered it in over a year, so I doubt it still works.
  12. I just acquired one of those rotten things. It uses the same mags as a carbine I have. Kind of a New West sort of thing. Despise the trigger. 🙂
  13. Actually, you did not state what and how many subwoofers you have. Having gone from 1 to 2 to 4 VMPS New Larger Subwoofers, that is another area where you can find improved performance. Have a look at the attached research paper. Mulitiple Subs - Number and Locations.pdf
  14. Gil and I exchanged e-mails, yesterday. He said to say "Hello!" to all of you. He is in a new facility in Chicago and finally getting PT. He is able to do some walking with a walker and is getting more use out of his left hand. He says it is slow progress, but I think it's grand! His old phone quit working and BIL Joe has shipped him a new one, due this week. Maybe he is a little harder on phones than some of us. 😉 I was getting concerned since he had been unreachable, but I think, now, that he's OK and getting what he needs.
  15. The K-700 makes for a nice sized lamp, nearly the same height as the ginger jar lamp that donated it's organs. It is now on my nightstand and the extra area of the base is usable for some of the stuff I usually keep there. A K-400, ..... hmmm?
  16. there is no difference in the performance due to the lead attachment method. But, but sure to use a good film and foil cap and avoid electrolytics in speakers.
  17. Not so much. Springsteen is sad and depressing. You know, it could have been an old Brubeck or Monk record.
  18. I would look at improving your room acoustics first (damp reflections and reverberation, the surrounds provide the intended reverberation). Then, look at upgrading your receiver. The RP-8000 speakers, at 98 dB/w/m will not challenge the power section of your Denon, so more power will only be noticed at very high SPLs. The preamp and processor sections of your receiver make a large contribution to sound quality and clarity, more than the power amp, in my experience. Adding a power amp to a receiver has become a fad, but I can't imagine why. Seems like racing tires on a tired Yugo to me.
  19. Thank You! It's a geeky sort of labor of love.
  20. I just tested a mounted K-700. When struck there is a short duration "ting". The K-700 is much shorter and has smaller wall surfaces than a K-400, making is naturally stiffer and less prone to ring.
  21. At 21 years old, you probably do not need new/refurbished crossovers (maybe not even at 41 years, in my experience). The sketchiest part is the replacement diaphragm and the skill needed to swap it out. I've got a squawker that had an open voice coil and I paid a well regarded shop in Nashville (they had some of Charlie Daniels' amps in for repairs) to replace the diaphragm and it buzzes on piano after. It was bought for backup, so I haven't tried to fix it again. The work looks deceptively easy. Your speakers only need regular use.
  22. You should use the center speaker designed to match your front pair. If your fronts are H IVs, use a 3rd for the center. If the RC-64 III matches your front mains, get a sound meter and calibrate your system. Sometimes movies are mixed so that dialog is not clearly audible. That doesn't happen regularly in my system, but it does. It must be a "style" for film makers.
  23. I didn't know you sold your MWMs! What I'd do is 2 MWMs and 2 La Scalas per side and cross the MWMs as high as practical. I would think that would be easier to find than a whole MCM 1900 rig. Maybe you could rent 2 KPT-1802 and some KPT-396s from Klipsch. I'll bet I can find a copilot or 2nd tow vehicle.
  24. On the floor and close to one, or more walls. Distance to taste. Most Heresies before the IV are a touch bright. I think they need a subwoofer because the response below 70 Hz is weak. I had 7 at one time. Four helped me buy H IVs.
