  1. The subwoofer driver would probably be grossly less sensitive than the Cornwall woofer.. plus it wont go high enough in frequency to meet the midrange cross over frequency at 600Hz. Plus honest.. the Cornwalls go down to 30Hz . you dont need more for all music apart from the most extreme pipe organ or electronic music with lots of exaggerated bass.
  2. who was the collector? I purchased a pair of LaScalas 15 years ago from user name "Dodger" he had lots of Klipsch.. and a wife that didn't appreciate it.
  3. yes it is all the internals of a KLF10 including the single port. (not shown) Yes I have 6 KLF C7 Woofers... Sadly for you they are being used as my center and 2 surrounds.. I got those parts before I found well priced C7s locally.. I was very lucky. I am sure the KLF10 would make a great center... in a smaller sealed cabinet.. but... in my small room its really overkill I also have3 KG4 tweeters and x over..
  4. try posting some pictures.... or try searching the web https://www.vintage-radio.net/forum/showthread.php?t=140793 http://audiokarma.org/forums/index.php?threads/a-tube-amp-restoration-walk-through.655366/ you can remove the bell ends if they are really rusty and refinish them. As for the laminates, Seems a good approach would be cleaning off with wire brush or light abrasive scrubber . Then prime with one of those rust transformer products and then rust spray paint. I would advise against rust removers as they will get into the laminates and continue corroding the steel. https://www.theruststore.com/Rust-Converter-FAQs-W48.aspx Have fun!
  5. Older thread I know. . what is the impedance of each woofer? 8 ohms or more? because the KG4 spec says 6 ohms. I have KG4 crossovers and tweeters, but no woofers.. wonder if the little Eminence Alpha 8 would do the trick. I have 4 of them!
  6. here is all the info read down and you will find link to official history
  7. What about just any set of klipsch speakers that have dual woofers, and redo the front board with the mids/tweets in between? KG4, KLF10, KG 5.5 any of the RF line with dual woofers and a tweeter. does it have to be a 2 way? What about sandwiching the mid and tweet of a KLF20 or KLF30 between the 2 woofers?
  8. Wow thanks for this thread. I just sold my Fortes today and kept my KLF20s and a pair of Heresys. I had misgivings of letting the Forte's go. Thanks for the chearup!
  9. yes these are mine... all original. https://www.kijiji.ca/v-speakers/ouest-de-lile-qc/klipsch-forte/1348268886
  10. I saw that too. I just don't understand where the come up with that other than their ***. Tin would theoretically increase the resistance as it is part of the outer circumference of wire. What they mean by "current jumps" is puzzling. Honest I don't know how skin effect changes between a solid conductor and stranded. Maybe the tining acts as an insulator between strands. If indeed that is the case, then it would allow the current to flow individually in each strand as opposed to the outer layer of the overal wire. But this difference would be so tiny. Theory yes, but practice, no.... it is so easy to make up this BS. It's fun. lots of "audiophiles" simply have no clue and no way of separating even remotely possible physics from total nonsense. And they get very angry when you point that out.
  11. Sounds like normal wire.. when the price is right. The description is hilarious though. Can't anyone just sell speaker wire anymore? This is just as good and much cheaper https://www.monoprice.com/product?p_id=2747
  12. May the Smith Chart be with you! Not intending to teach crossover design. but perhaps some basic L and C circtuits.
  13. As an engineer I try to help explain basic electronics such as ohms law to non technically inclined or to people that wish to lean more. There are many sites that have electronics tutorials but I have not found any that relate the knowledge to what you need to know as an audio buff. Lots of examples on ohms law but very few on how to apply ohms law with basic circuit theory to do some rough calculations on speaker cables and impedance, bi-wiring, bi amping etc. or other basics as applied to audio. Trying to give people enough knowledge to differentiate snake oil from what matters. Anyone find something that is just enough for beginners in a audio context? Thanks.
  14. would be interesting to see what is inside those switches. Most of us just want a switch for 2 amps and 2 or more speakers. Those switches have transformers and volume control so that the amp does not see too low an impedance load. Could you open it up for us? What is the volume control? An L pad? "just need a switch"
  15. there are no labels anymore. But I figure that there where not many finishes that had the end grain ply wood visible. Others would be veneer.
  16. Help in identifying these.. H1 of course but what finish? You can see the end grain of the plywood sides on the top in the photo. Sn 171y737 y implies 1983 I gather from the Heritage codes sticky. thanks
  17. And its difficult to find the good old jewel boxes. Not the thin ones, the originals. Not that they where much better, pretty much every one ends up breaking.. So I found someone selling all their old unwanted CDs.. I don;t blame em.. mainly country music... at less than what I could buy new jewel cases for... like 50 of em for 20... so I have enough to last till I go deaf.
  18. Seems like Indigo Electronics in Canada was a major supplier of these BASH amps to many companies. I found identical schematics in Klipsch, JBL/Infinity subs and powered speakers. Trying to fix mine!
  19. Repairing mine now. The Indigo Bash amp is the same as in others including JBL and Infinity subs. Some of those service manuals are more complete, including bias adjustment after mosfet replacements.. and they had the value of my burned inductor.. 150uH. Making one myself. Already found 2 Mosfets blown in the PWM power supply. Have my parts list ready to go.
  20. caps will vary depending on voltage: For double the voltage breakdown you need 2x the plate separation for the same volts/meter. Dielectric constant: if the material is 2x the Er then you get 1/2 the plate separation. Equivalent series R: related to plate conductance and different choice of dielectric. Will really all depend on the construction and materials used and specs desired
  21. Hope you got them! its been a few days!
  22. Went to the Montreal Audio show last night specifically to listen to what Klipsch had there. They had a pair of ForteIIs! Just wow! Very well balanced, gorgeous cabinet. Perfect imaging. (and that is what I went for) The only thing was that considering the size and market share of the company, they could have had a bigger room with more wow factor to really show them off, considering they where the cheapest of the lot that I liked.. The local shop is not that big. The other makes that struck me in a positive way where the Yamaha NS5000s, $20,000 Paridigm Persona $30,000 and Muraudio $14000(made in Ottawa!) electrostatics. Source material makes a huge impact though, maybe other demos where just not my type of music. Lots of $5000 power cables too! Oh boy. try getting into a conversation with the reps on those types of products.. Lots of BS and real anger when you ask good questions. The same sort of response when you ask CAM people about reiki and homeopathy... its all woo.. and lots of Quantum Energy Fields!
  23. a good car audio amp will do . Most today are digital. You can get used ones on most local classfied pretty cheap. Pioneer, Alpine, rockford fosgate are good makes. There are many. You will have to connect to car ground and battery with hefty wire.. 8 gauge minimum. Depending on the use, like many said, they are very efficient you only need a few watts. what about a 12 to 120 v inverter and a normal amp/receiver? Or just use a car am/fm head unit.. also for sale used cheap.. most will put out 25wpc x 4 peak a good 15 watts pc clean.
  24. To everyone, and to Jerry (TFR1) in particular. Please accept my apologies for my overzealous reply. Sorry Guys. My bad.
