  1. A friend of mine from years ago had a Filipino wife and she made something with anchovies and other stuff. Chuck called it dirty socks and she was forbidden to cook it inside. It tasted really good on green peaches though.
  2. Good morning OD and great to see you flogging your tired horse again! Cant say I have found any voids in Baltic Birch yet but the Chinese version of it is full of them. I expect that from them though. Remember to stop in and hear a real system when you have a chance. I did not pay a lot of attention to the plywood used in La Scalas until I considered making my own speakers and alterations and then this was what I saw. On the last five sets of LSI's and LS's here the ply's in the plywood were not like the ply's in the Baltic birch and were typical of what you would see in regular plywood at the lumber yard. I have had a number of sets before this but did not pay attention to them. I remember reading somewhere that Klipsch used Fir plywood too and this might be what these had. After having cut into a number of sheets of true Baltic Birch I have yet to find a void. The Chinese stuff however was full of it and even the wood was a different density and much lighter than the real thing and had a different tone to it if you would hold a piece up in the air and tap on it. Grossly inferior material.
  3. You have to ask the voices in your mind and then decide which one you want to listen to. They will let you know what is real.🙃

    Yes and they won't be there long I figure.

    I saw your post after I posted but left it up anyway just to let people know John is OK to deal with.

    I have dealt with John a couple of times and he handled himself well each time. $2300 asking price https://nashville.craigslist.org/ele/d/murfreesboro-klipsch-klipschorn/6938926458.html

    500hz it will be. You are right to caution on going deaf. Since these arrived my wife complains she has to repeat herself. It is too easy to turn these up and I have had to get a DB meter to monitor things. On my final plan I went with a circle drawn at the end of the plenum that would contact the sides and back and also the faces of the diverter figuring to keep the expansion rate as high as it could be. Is this a what you would consider a zero to positive expansion rate?

    You need to buy two so you can sell me your 904's cheap. As a matter of fact if you wish to not get your hands dirty I haul big hard to handle objects free sometimes.

    Yes I did and it does sound good. What was even better was a Japanese fireworks video I downloaded from Youtube. Fantastic fireworks and up to 48" shells so lots of boom which these do rather well if I must say.
  11. So why are you even asking this with a pair of tasty 402's in hand? Are you looking to build out parts you have sitting around? If I owned Cornwall III's AND owned K-402's I would be selling the Cornwalls to fit something good under the big bad horns. Cornwall tweets and mids are quite anemic compared to 402's. If you needed to save space for another listening area my choice would be to sell the Cornwall III's and find a good set of Chorus speakers to upgrade and use the money left over for something else. If you are

    Not analyzing as much as looking for best practices from people who have been there before. It is a shame there is no way to visualize sound waves as they propagate and see what works best. They have FEA software for many things now but I don't remember reading of any for sound waves and I expect the market of potential buyers is to small for programs being written for it. Really I am quite happy with the results but if there is improvement beyond electronic tinkering to be had I am interested. You never know until you seek the answers and at some point in time someone has to try it too. Sound propagation seems to be one of the fields that does not have specific rules laid down with proven singular best practices and so we see all the competing designs and no clear cut winner. I regard Paul as a genius having come up with what he did and I assume some math and lots of intuitive engineering insight to do what he did before computers and software was around.

    Actually what I would do would be to open the cad file and derive precise dimensions and prebuild the whole thing and then make a removable panel on the back side which would allow me to change things around at a whim. By the way on the Edgar attachment I never had a page 13. This does make sense in that it does more uniformly continue expansion where the straight dumping from the plenum end to around the bend does not have that as is.

    Yes this is my plan. I might still pursue a better splitter or diverter after I get things set with the xilica just to see.

    I had thought about cutting a square panel out of the back side that could be mounted back in with various sizes of deflectors. I really only need that section to be removable. The idea of a curve on the deflector on the backside and the inside corners to make sound "flow like water" with fewer ripple inducing disturbances is something I had discussed before but seemed to draw no interest or definitive answers. With limited knowledge but thinking practically about things it just seemed to me that sound could handle to some degree like water or air flow and curved transitions would enable more uniform flow with fewer "eddies" in it causing audio problems. I see tons of sharp angular transitions in speaker cabinets though. I would think curved corners would also break up any standing wave problems these S-MWM's might have.
  16. Yeah I know what you mean. Last night the wind was howling through the grove of trees on the ridge when the thunderstorm blew in. 🤩
  17. Absolutely. The goal you are pursuing is well worth the trouble. When you get it all dialed in watch the faces of your fellow music lovers when they first hear them. I buy fix and sell old Klipsch and I NEVER let them hear the big box until we are all done and they agree what they bought is nice. Then I let them hear much better than nice. You listen to pro gear set up right as your daily music source you can forget what it sounds like to someone who has never heard it before. Familiarity does not breed contempt but you can forget how thin all the other stuff is in comparison and the look on customers faces when the big boys fire up reminds you of that. Darned right. Familiarity will never breed contempt for what you will have but it is nice to have new listeners remind you once in a while what you really DO have. I never let buyers hear my personal system until they have decided they like what they came to hear and buy them. THEN they can listen to what is not for sale.

    Also a bump on what the lowest practical hz limit is on the 402+1132 combo. I have seen the literature on various drivers but asking for practical real user experience or tech advice from someone who knows.

    Scrolling back through this thread to reply to someone and I was thinking how hard it is to get information sometimes. I had discussed a splitter with the La Scala being bigger and having an arc to it with with corner rounds on the outside internal corners also figuring sound might behave like water and rounded transitions would create less "turbulence". Among those who responded the idea was it generally poo pooed and that is why I did not consider this for the S-MWM. I had also posted pictures of the splitter before install but I guess no one caught that to tell me other wise. There were also comments to the regard that PWK did not have splitters in the MWM and so they are not needed. So what I am doing today is trying to get definitive best practices for the splitter and the outside corners. Due to the size of the cabinet and the degree of difficulty in holding it all squarely in place I had to make the back to be glued in and change is not going to be simple or easy. I am willing to consider doing this is it will bring about significant improvement. I would like to hear from those with real practical design knowledge and or hands on build results they can tell me about that incorporated this kind of idea. It is possible to make this from say 1/8" formed aluminum and screw these things in from the front without removing the back.
  20. True as the subtleties of Tannerite are better witnessed than discussed.
  21. It is also nice to see droll humor is also successful here 🤣
  22. Say if you are ever in the area stop in and hear a real system. Then we can migrate to the ridge top for a little target practice, carcinogenic bar-b-cue and Tannerite.
  23. Buy the 20 pack of 1/2 pounders then. You do know the main goal is entertainment right?
  24. Looks like a home build. Construction inside the mid horn bin is not Klipsch and the mid horn driver and crossovers are not either as far as I can tell with the grainy picture. Basic box looks good though so the right components will give you a great speaker. No telling what your woofer will be. I have had K-43's and K-33's, generic Eminence (more than one type) and speakers marked "Taiwan" for the brand name and model number.
  25. They might be but that does not stop the satisfaction of giving them a hard time in a most entertaining way.
