  1. How does this turn into a 300% price increase? Shipping is pretty bad to some places and approaches $85 but unless there is a huge import fee I don't see how it gets a price tag like that. Oddly enough the worst country I have had to deal with has been Canada. Expensive, slow and they damage things.
  2. I quit trying to make these work because other projects were more important. I still think there is something good to be had there and have passed them on to someone who knows a lot more about this type of thing than I. He will be trying these out on my new 14 x 7 wood horn. I will say that on my Super MWM's here I had crossed over at 500hz before I have found 650 to 700hz sounds better. This is new diaphragm material on the 314 and the next offerings should be improved, if they do offer more. I have been advised to have the lowest crossover point possible to the horn but playing around with the Xilica is leading me to believe that does not always work. There are potential medical problems with my wife that have me concerned but I am fine. I want those 314's to work. The first time I head them it was pretty striking. I think it was the percussion and higher string notes were so clear but over time as daily listening went further I began to realize I was missing other things. The mind can play tricks on you with initial impressions. Hope things are OK for your family.
  3. Yes and as our hearing degrades over time it is nice to be able to to boost HF and be able to hear certain sounds again.
  4. I have thought about experimenting with different colors of paint on crossover boards and adding various powdered metals to the paint.
  5. I use them only on one driver. Like on the KPT 904 to tame the 510 horn + DE75 down with the factory crossovers as they were to strident otherwise. There might be better ways to do this but it is all I know to do and I am not a crossover expert to know what to alter to balance the HF to the LF on a two way like the 904.
  6. Well I wanted to sit next to the 32' organ pipes and that was a specific goal. I wanted that realism and those double 15" woofer bins you now have are what made me wonder just what was possible.
  7. So Jim you have made the transition from 1 15" woofer to two and see the difference. Wait until you hear the KPT 415-LF's. Nothing quite like watching someone get sucked into the dark side of Pro Klipsch.
  8. Word of warning. DO NOT listen to any variants with that big ugly no good 402 plastic horn on them.
  9. You are DOOMED! Once you hear them you can't go back.
  10. I wondered about that too. Those new CF4's are a tightly integrated system and I for one would never second guess what Roy has done. I am thinking if I was not happy with them I would start looking at pro line speakers. I understand the fun of experimenting but not on something like CW4's
  11. That was my old Solid Edge CAD program blog. Since I no longer work professionally doing that and I am no longer part of the Solid Edge fan boy club I have changed the title and main topic. Not much posted yet though.
  12. On wood not much. Carbide will last a long time. On metal parts it depends. If you match the right carbide grade and tool for the job + correct coolant + hydraulic tool holders and then run it with a good CAM program you can get a lot of life out of things. One of the biggest improvements in tool life for me was adopting high speed machining tool paths. Tooling can be a significant one time expense still with new tool holders but carbide is no longer as expensive based on parts cut with each carbide tool.
  13. Get a piece of fine Scotchbrite like the maroon 7442 pad and very lightly buff with it.Heavy preasure will leave to much scratch pattern.Also dont swirl it around but rub it back and forth in one direction along the long axis of the wood. Fine steel wool might be even better but remember to start with minimal preasure no matter what you do.
