  1. Don't let the above comments about the "missing" tweeter deter you. I don't think there are any missing pieces.
  2. Guys this is a garage sale forum. Let the poor guy hawk his wares. If you don't want to buy them, then don't. Although, I do think this guy (vendor) would do himself a favor by not trash-talking other vendors.
  3. I am afraid you folks are missing the point. Reading the original description over at DIYaudio is important. In the test, you listen to music (from a CD of your choice) as loud as you like it (and then some). At this point the "volume knob" is not touched. Now you put in the test tone that has been recorded a specific amount (dB below full scale). This tone simply provides a steady state signal. With this steady state signal, you measure the RMS voltage at the speaker input. The value is squared and the resulting number is equivalent to the wattage the amplifier needs to provide. This number includes "headroom", "transients", "steady state" etc. The amazing thing is the number is small. For high efficiency horns, the number is very small. Again this includes dynamics, head room and all the other stuff. Unlike what is stated by others above, you really do not need a 100 watts, In fact you only need a few watts (if even that). Ignore all the conjecture about head room etc since that is already rolled into the original "adjustment". This test really is an eye opener. An amplifier with a few watts may be sufficient (high efficiency horns with a reasonable impedance ). IOW, your listening peaks are certainly less than 85 watts ..... much less.
  4. I agree. Unfortunately, most dressed up speakers end up that way. Why do most think that furniture (this ultimately is what a speaker cabinet is) must "stand out".
  5. ------------- If this is the signal Pano used, then you are off by x2. Simply measure the test tone at the speaker input and square the value
  6. You need not worry about the dynamics or headroom. That is already taken care of when you do the initial test. First, have a look at what Pano did and assumed for this demo over at DIYaudio
  7. Sine waves are not the issue in this demo. They are simply used to provide a steady state signal when you measure the set up with a volt meter. Have a look at what Pano assumed and did for this demo over at DIYaudio.
  8. That is an unfair summary. ALK is well-respected by a number of folks.
  9. I agree with the above. If it really takes 5 people a full year to build two pair of cabinets, the company will quickly go broke. I also agree the horn is probably a JBL 2360. If it is, that is not JBL's best effort. edit: taking another look, it might be an Altec. The JBL had an "extra" section on the throat that the driver bolted to. I can not see it in this picture As far as the veneer goes, yes it is a pretty veneer and finish. However, given the cost it does not seem that attractive and your wife is sure to hate it. You will end up having an expensive veneer item "sentenced" to live down in the basement
  10. For those of you in the mood: CraigsList (Eastern CT) has a pair of Chorus and La Scala for sale. The asking prices seem competitive. Other than that, I know nothing about them. Specifically, they are located in Norwich CT

  12. It is a long shot, but check the Craigslist for Rhode Island. It is a pawn shop, I guess, in Providence that has some Belle Klipsch. That have had them for at least a few months. Perhaps you can make a deal with them. Who knows
  13. John, I am glad you found an amp that you are satisfied with. You did make one comment that I find curious. Did you really mean to equate the Nelson Pass products (Pass Labs, First Watt) as being for the "Kool Aid types"?
  14. Congratulations! I know you will enjoy them and I know you will give them a loving home.
  15. Guys let's keep the perspective in mind. The Pass labs amplifiers are not special purpose, rather they can be used with a variety of speakers. The First Watt amps are designed for situations where 25 watts or less is adequate (perfect for horns). The BAF amps are meant as instructional devices. Although they may have some nice qualities, I don't imagine they are meant as final substitutes for Pass Labs or First Watt products
