  1. Ha! Yes, a pocket protector...and I'll go with a pencil sharpener.
  2. Know what you mean. Always fascinating when some random snippet on social media can trigger long-dormant memories.
  3. Get some unsalted shelled walnuts at the grocery store. Fresh nuts have a certain amount of oil in them you want on those scratches. Literally rub the nut into the scratch areas in all directions. It will crumble a bit and make a mess. Wait a few minutes then rub out the area with a clean cloth. This is about as cheap and easy solution as you get. It won't remove the scratches but will greatly disguise them.
  4. Personally, I would have no issue deviating from spec as you mention. There is always a a fair amount of variation in component specs. Sometimes they average out if you replace with a lower value, but not always. Capacitance meters are not that expensive if you want to go that route. Remember, you will need to scrape off the wire varnish if you reduce coiled wire in a higher value piece.
  5. Very nice, for sure. Some like all black finishes but for me the exposed wood grain finish is the only way to go.
  6. So, some comment on the pop report. That does not sound like an issue related to the caps in your xover. It is more likely that you are bottoming one or the other woofer coils at the very high sound levels you mention. If this is the case, then there is no quick remedy for that other than backing off the drive power. Are you using equalization of any kind to boost the bass response? Check on the passives in the back to make sure they are in good shape and not leaking air.
  7. The crossover topology for the III has some significant differences from the I that may be of interest if you drive the speakers to high sound levels on occasion. The III crossover may be more effective than the I in dealing with high power to the drivers.
  8. The foam is there to suppress some of the sound energy bouncing around in the enclosure. As sound waves pass through foam, fiberglass or similar, some of that energy is converted to heat from the friction of passing through the fibers/cells. The amount of foam or enclosure stuffing is always a balance in what you are trying to achieve. Here the amount of foam is relatively small and therefore targets mid range frequencies that could set up standing waves. Using a large amount of stuffing in a sealed enclosure may act in a way that allows the woofer to "see" a larger enclosure. But this also changes the Q of the speaker considerably so some amount of thought should be given in how you are affecting the enclosure and woofer as a system. Personally, I do not care for the sound of highly-stuffed enclosures. Too much constriction in dynamics. I have tried this on limited occasions so experiences may vary.
  9. Just to be clear, you purchased the equipment direct from Klipsch? Not a dealer?
  10. I have an ATI AT602 I have had for a long time. I use it as my dead-center-of-summer amp with the original Forte speakers. It does not have any audio cache to speak of but it is a very good quality, build and completely neutral, and runs barely warm. As an out of left field suggestion look at the Schiit Audio Aegir. Modest in size and power (20 watts) but runs very high into Class A bias and is a stellar performer for $800.
  11. If you block a port in an enclosure designed with a woofer optimized for that enclosure size you will end up with a too-large enclosure and a low-Q bass loading for a sealed system. You will end up with a shelved low bass response tapering off up around 200Hz and well down in bass response below 100 Hz compared to that same woofer in the ported enclosure. You might gain some power handling but you shoot the bass response all to heck. I would not suggest to anyone that plugging the port of the IV, or adding a vent to the III is a good idea.
  12. Do you the know the make and model of the woofer? Does it have a vent hole in the magnet? There seems to be enough movement to make sound waves but something is limiting the travel. So, a warped coil former, loose coil winding or something in the gap.
  13. Annoying is just what it is. What has come about lately in the audiophile community where "we" can finally accept speaker designs such as Klipsch? After decades of disdain and indifference? I hope that that it means that the elements that make reproduced sound seem more real (to paraphrase Guttenburg) have finally cracked through to the top of the list of sonic priorities.
  14. Do they fit down part way into the cutout? I was thinking cutting out a thick casket of cork or similar that will seal off the fitting without having to set down so far into the cutout. Appearances may differ but they are on the back of the speaker.
  15. Yes, apologies, I was not following the thread too well back to your original questions.
