wallflower Posted July 1, 2007 Share Posted July 1, 2007 Are the dimensions of the 60th Anniversary Khorns the same as standard Khorns?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> After looking at the 60th Anniversary Khorns it appears the backs do not exactly complete the bass bin of the Khorn as was originally intended (?). It looks as though the backs are inset into existing Khorns which would seem to remove some (albeit little) volume and throw for the bass horn (ex. Volume = 3/4" X the area of the backs). Correct me if I'm wrong, but when Khorns are placed in a corner, the wall is what completes the backs of the cabinet and the wall rests against the back of the speaker rather than being inset in the speaker, as it appears on the 60th Anniversary Khorns, which leads to my following questions... 1. Is my assessment correct of the build of the 60th Anniversary Khorns OR did they change the design (i.e. increase the size of the cabinet) to accommodate the backs to remain true to the original design intent? 2. If they 60th Anniversary Khorns are of standard dimensions, does it really make much if any difference if the back is inset in the cabinet OR is PWK's original design somehow compromised by this alteration? It would seem if there's a compromise to the original design, that the easy solution would be to add backs truly on the back of the Khorns, which wouldn't be as aesthetically pleasing to the eye as the 60th Anniversary versions, but may be more exact in terms of completing the bass horn. With the help of a fellow forum member, we're about to undertake this project and before we start cutting I'd appreciate input from the forum. Thoughts?

Guest " " Posted July 1, 2007 Share Posted July 1, 2007 During the late 80's I built 2 pairs of Khorns with the attached corner arrangement as used in the 60th edition. One version started as acutal size, the other was 15% larger. In both cases I had to increase the size of the top section, and the top shelf of the bottom section, in addition to adding a false floor, sized extra to account for thickness of the attached false corner walls. The result was no change in exit path mouth size. I don't know what approach was used in the production model. Quote Link to comment Share on other sites More sharing options...
wallflower Posted July 1, 2007 Author Share Posted July 1, 2007 After checking the specs on the Klipsch web site, it appears the dimensions of both the standard Khorn and the 60th Anniversary editions are identical. So the question is, does adding a back on the Khorn -- like the 60th Anniversary edition, which is inset -- and which marginally minimizes the throw compared to a Khorn against a wall, compromise the bass extension of the LF coming out of the bass bin?

colterphoto1 Posted July 1, 2007 Share Posted July 1, 2007 are you thinking of buying a pair and wondering about the bass response, or just second guessing our engineers? Quote Link to comment Share on other sites More sharing options...

It would be one heck of a math drill to calculate the possible variation. Quote Link to comment Share on other sites More sharing options...
gaspr Posted July 1, 2007 Share Posted July 1, 2007 Wallflower. Good question and something I have wondered about as well. Anyone thinking of closing the backs of their khorns should be asking this very question. Seems pretty straight forward and should not be very hard for someone at Klipsch to answer???

wallflower Posted July 1, 2007 Author Share Posted July 1, 2007 Michael - I want to make sure about the way I'm going to put the backs on my Khorns. Judging from the pictures it looks as though the Klipsch engineers determined that putting the backs inset is not an issue. Just wanting to confirm what the pictures seem to indicate. Bob - Thanks I've already thoroughly perused that thread. Thanks! Quote Link to comment Share on other sites More sharing options...

gaspr Posted July 5, 2007 Share Posted July 5, 2007 Sure would be nice to get an answer to the original question here...maybe Speakerfritz has his anni-k's and would be kind enough to oblige??? Quote Link to comment Share on other sites More sharing options...
Guest " " Posted July 5, 2007 Share Posted July 5, 2007 "Sure would be nice to get an answer to the original question here...maybe Speakerfritz has his anni-k's and would be kind enough to oblige???" mine have not arrived yet. someone posted they were the same size, which means the back sections are inserted within the exiting khorn architecture. For that to work....you might need a false floor as well. Quote Link to comment Share on other sites More sharing options...
wallflower Posted July 5, 2007 Author Share Posted July 5, 2007 Well we (I and another wonderful forum member (Tom Keady)) just completed the 60th Anniversaryesque updates to my Khorns. I have to say that Tom's skills are extraordinary and there's simply no way I could have ever done something like this without his help. Thanks a million Tom!!! I have to report that the project was a complete and total success. We took many pictures throughout the process and will share them when I get the chance to upload the pics. I can also report that IndyKlipschFan is absolutely correct about the results. It's stunning. Currently I have perhaps one of the worst setups you could imagine for a pair of Khorns and they sound wonderful. The bass is deep, full, rich and extended. I don't even have a corner for one of the Khorns and it's still producing amazing bass. My entire basement is energized by these things. Before we put the backs on the Khorns they were completely lifeless in the bottom end when out and away from corners, but now they're tremendous. You can toe the speakers anyway you want and they sound fantastic.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Thanks to IndyKlipschFan for his many insights. Thanks too to the fine folks at Klipsch for their guidance. And thanks again to Tom Keady for being such a great friend and helping me undertake this rather large project!!!

IndyKlipschFan Posted July 5, 2007 Share Posted July 5, 2007 YES>>>>> Feels good, doesn't it, to be right? I am so happy you feel the same way. More people will do this IMO too!! I am glad all of our chats the last week or so have gone well and I "converted you" as a believer! If/ When (and I do think they will) Klipsch does this on regular production line K horns, watch the HUGE tidal wave of people do it as well.

Guest " " Posted July 5, 2007 Share Posted July 5, 2007 " I don't even have a corner for one of the Khorns and it's still producing amazing bass. My entire basement is energized by these things." I made a set of khorns (15% oversize) with such backs during the late 80's and used them for a picnic in an open field for 3000 folks.

tk49 Posted July 5, 2007 Share Posted July 5, 2007 Jeff, thanks for the credit, it was a pleasure. Where else am I going to get the chance to hear some fantastic speakers? I was astounded with the way they filled the room with live sound, the entire room was a sweet spot. The forum members are a great bunch, very supportive of each other and free with valuable information. The false wall mod is a major improvement when your floorplan isn't the best.
