  1. I would sure like to know where you guys see all these cheap Chorus's. I have been watching and nothing anywhere within hundreds of miles from Nashville for anything even remotely close to that for about a year now. Forte's are selling for $650 around here in a heart beat. If you are including the whole United States that might be true but then the 1000 to 1400 mile round trip kind of removes the value of that "cheap" price. I would like to buy some from you if you have any for sale at the average price
  2. Before you ever go to look at another speaker do this. I have and it works very well. Go buy a $38 lepai amp from Parts Express. Add to that a small AC inverter that plugs into your vehicle power point or cigarette lighter. Next time someone says they can't play them you just hook up the Lepai from your vehicle and have enough power to check things out for big problems like drivers being fried. $100 spent will prevent anyone from ever hiding behind I cant play them from ever happening to you again. A wall outlet works just fine too and it has a USB port so load your flash drive with test music and have at it.
  3. They sold for that too in four days.
  4. THANKS John, it was the physics of the situation I was wondering about and you have explained it.
  5. Need to get one maybe two of these.
  6. Moray let me try to explain it like this. A direct smaller connection will have a smaller volume of air to deal with. Air is compressible and therefore my thought is larger volume with the whole speaker interior to cushion the effect of sound waves, reducing compression so to speak, would not yield the same compressive transfer of energy to the passive as a controlled direct square pipe between the two would. The answer is something not addressed yet and it is will this work and does it make sense or no it will not work and here is why. Yes I get the idea of volume for bass but is there a way around that is the question I am trying to ask. I am figuring to some degree sound is like air. Blow it into a box and yes it will hit the other side and every other part to. I blow that air into a sealed chamber between two points it goes from point A to point B and does not fool around with dissipating its energy. I don't know how to explain what I mean better than that. Listening to how directional the sound output from my La Scalas are tells me that sound can be directed and channeled. Horn designs have an angle of sound coverage. So to my mind without technical training in this field shape can improve sound wave transmission.
  7. I have a re-coned K-1001-K Quartet woofer and a re-cone kit for the same. I am tired of fooling around with trying to sell it on EBay and figure if I am going to give it away it should be done here. So pick up the price of shipping and I will send these to the first respondent. Thus ends my sojourn into the world of re-coning.
  8. I had a quote recently for K-42 and they were $194 each plus shipping. I want to say a number I heard recently for Klipsch direct k-43 was around $224.00. I ended up buying Eminence woofers recommended elsewhere on the forum as a replacement for the K42 for $124.00.
  9. OK maybe sealed chamber would be better as a description. I can still take and recreate the volume of the, lets say a Forte, and make the cubic feet inside the chamber the same as the open area inside the Forte. What my question really is does a a contained "stiff" column of air offer any improvement over a box with air which would I assume act to some degree as a shock absorber and be subject to potential interference from mid range sound waves freely roaming in the same area? That is an interesting site John. Do you suppose that plastic tubes would be a violation of sonic purity construction methods
  10. OK a picture is worth a thousand words and here is what I mean. A sealed chamber from front to back and side to side. Besides adding stiffness does this accomplish anything? I ponder improvements and recognize the genius of Klipsch. Someone will come up with the exact perfect acoustic variables some day I suppose but are we there now? I go back to everything is a compromise in manufacturing and what we can do today as individuals does not depend on some CPA penny squeezer cutting corners. I am interested in utilitarian solutions and wonder if this plenum idea would work.
  11. Hi John, JAMS? When I last spoke to him he was moving, too busy and recommended the guy who is sitting on my money and K-42 core. Since re-coning is turning out to be such a chore and results not optimal I have ordered two sets of Eminence woofers. By the time the dust settles I have something right away, price is at worst no higher and in this case cheaper. Mailing two ways and then paying the East Nashville dude would end up running me about $135.00 and the new Eminence I went with is $125.00 each. I would prefer getting the original K-42's re-coned but I have no good answer yet.
  12. Catching up and these replies are not encouraging. If I am not going to get factory specs with the re-cone kit I might as well buy new Eminence woofers. By the time I pay the re-cone dude in Nashville for incorrect parts I am over two thirds of the way to new. Actually in the case of 15" K33 woofer replacements I am money ahead by buying direct from Eminence. Surely there is a better answer.
  13. OK I find I have a need for five K-42 woofers. Klipsch quotes for retail customers is $194.80 each plus shipping. The Eminence Delta Pro Eminence Delta Pro 12-450-4 4 ohm speaker. The Eminence Delta Pro 12-450-4 is a 12" 4 ohm speaker. The Delta Pro-12-450-4 speakers available here. is $109 each plus shipping. Is there any reason not to use the Eminence? If I were to get these old K-42's re coned does anyone have an outfit they use that can restore to exact factory Klipsch specs?
  14. Please check your mail.
  15. Question for you experienced speaker fixer uppers. I had a K-43 re-coned here in Nashville a while back. It was supposed to be an exact duplicate of the factory specs. I recently ordered a re-cone kit for a K-10-K from Simply Speakers and it had a lower Db rating by about 1.5 if I remember right then the factory original. They said it was their K-10-K re-cone kit but it was different than factory specs. This re-cone guy orders kits too and the K43 he re-coned now requires the balance adjusted to favor it since it appears to need more watts to drive it. No wonder he said both should be done to make the sound equal. Now you know the back round my question is where does one go to get exact factory spec re-cone work done preferably close to Nashville? Coulter has suggested an outfit in Indianapolis and I have an email into them but no reply back yet.
