  1. It looks like cosmetic damage, but, ........ You paid for new, undamaged. Make sure you get that.
  2. It does if you are building a crossover and need to match levels. I have specs for a tweeter on an exponential horn, but not the Tractrix I want to use.
  3. NO conductor does that. The electrons jump from one electron to the other by displacing an electron in the outer electron shell of the next atom. The outer shell, think Pluto, is the least strongly attached to the nucleus (Sun). The "jumps" occur randomly and, guessing, because the surface of the conductor is a discontinuity perhaps a slightly higher percentage of jumps occurs there. Maybe that is the source of the "skin effect" story. Stranded conductor wires are very flexible. Solids are not. Wanna read some nutty hokum? https://www.gcaudio.com/tips-tricks/electrical-delivery-systems-overview/ I worked for a power company for more than 30 years. The power system looks like drinking from a dam's spillway to any electronic component. Then, there are the "Green" electrons that always run on top so gifted people can see them. The coal-fired "black" electrons just hide deep inside doing the heavy lifting. We don't talk about the embarrassing blue glowing electrons.
  4. The online version does. http://www.klipsch.com/products/reference-in-wall-speakers
  5. Changes should be made to address a problem identified, not for fun.
  6. My 1967 H-700 has a black plastic pie slice logo like the ones Steve found.
  7. O.K., What is the change in sensitivity between a Tractrix and exponential horn using the same compression driver?
  8. Easy Peasey! Buy some open weave fabric like you see on cubicle walls. Make wooden frames 2" thick, install 2" duct board and wrap with your fabric to make it pretty. http://www.owenscorning.com/NetworkShare/EIS/57577-QuietR-Duct-Board-Data-Sheet.pdf http://www.soundproofcow.com/acoustic-panels/ You can also hang tapestries on the walls. Less effective, but potentially more attractive. If you have an issue with tones below 125 Hz, you need bass traps. I imagine your issue is in the 500 to 4000 Hz range.
  9. I think that's an Old Audiophile's Tale. Must sell newer snake oil! New electrons bump the outer/easier electrons from one atom, randomly, to the next until they spill out of the conductor at the other end. You don't remember the '90s fad of 20 ga single, solid cu speaker wire or the magnet wire fad of the 2000s?
  10. Yes. Klipsch did a double-blind speaker cable test at one of the Indy Pilgrimages. The braided CAT5 tested flat to something like 350 kHz. The nasty looking test lead wire was the 2nd choice. I have 10 ga equivalent, teflon insulated (reduced capacitance) braided CAT5. I could not tell the difference between my DIY CAT5 and old monster cables on my La Scalas. I chose the CAT5 40% of the time in the test!!! Fail. http://www.audioholics.com/gadget-reviews/diy-speaker-cable-faceoff Mr. Paul used what looked like 16 ga lamp cord.
  11. Why/how did you toast 3 receivers?! I had Parasound amps for a long time, including an HCA-1000A and enjoyed their sound immensely. However, I have to send the 1203 back twice because the speaker relays would get bad and cause low output in one of more channels and crackle/static noises. All under warranty, but the 2nd time I got it back, both went on ebay. I have had zero trouble with my Acurus amps. Better cables wouldn't hurt, but don't spend a mint on them. The cables I would recommend are not available. Look for cables with tight fitting, gold-plated metallic ends under $25. https://www.amazon.com/gp/product/B0009JR3R0/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 https://www.amazon.com/KabelDirekt-feet-Stereo-Audio-Cable/dp/B01IF3YW7U/ref=sr_1_12?s=electronics&ie=UTF8&qid=1495487584&sr=1-12&keywords=audio+cable+male+to+male
  12. t sounds like a placement issue to me, too. I wouldn't blow a bunch of money on $$$ speaker cables. In 2001, Mr. Paul was using 16 ga lamp cord.
  13. Welcome! You may be able to touch up the finish with spray lacquer. Even car wax may do the job, since they are glossy. As to the components inside, hook them up to an amp and gently, slowly turn up the volume while listening for unusual sounds and distortion. If all of the drivers are working and sound fine, enjoy. If not, this is the place to come! Collectively, we have lots of spare parts and know where to get new parts with even greater sound quality. If they are over 35 years old, I predict you will eventually want to replace the crossover capacitors to restore their crispness/livelyness. So far, speakers that I have seen that have not been used much and are also 40+ sound dull and need new caps.
  14. I believe clipping gets blamed because clipping is so often involved, but the real problem is the average power levels are too high. A clipped amp will be putting out a lot of average power, something like a compressed track. Add the HF required to create (created by) that square topped clipped off wave and the tweeter gets a double shot of energy. Van Halen's "Runnin' With The Devil" has a square wave generator applied to the guitar. This was my first clue that a clipped amp sounded worse than it was damaging. Square waves are found often enough in music that a speaker should be able to tolerate them.
  15. You always want several of the most capable subs you can afford. I often recommend 2 lesser subs to folks wanting to stay in a budget. More subwoofers will have more cone area and thus will generate XX dB with less cone motion (and stress) each. That will generate less distortion. Having had 1, then 2, and now 4 of the same subs, I can heartily recommend multiple subs. By being in different places they will not all excite a single room mode and you will get more even bass response throughout the room, in addition to prodigious output! You can always turn the throttle back, but you can't turn it up, if you're already max'ed out.
