ricktate Posted September 21, 2003 Share Posted September 21, 2003 I dont think false corners made out of cork is good idea,,,,might be ok in a pinch,,,but do make proper corners for your K-Horns and seal them to the corner tight....it does make it work better,,,rick Quote Link to comment Share on other sites More sharing options...
edster00 Posted September 23, 2003 Share Posted September 23, 2003 ricktate is absolutely correct, the false corners need to be very substantial. I made mine similar to the construction plans I posted, out of 2x4s, ¾" plywood on the speaker side, ½" plywood on the back side and floor (for the speakers to stand on rather than stand on carpet). I stuffed the interior of the false corners with insulation before attaching the back side plywood. Quote Link to comment Share on other sites More sharing options...
Hel Guedj Posted September 24, 2003 Author Share Posted September 24, 2003 But my cork panels are 3 inches thick Isnt' it enough ? Quote Link to comment Share on other sites More sharing options...
Hel Guedj Posted September 24, 2003 Author Share Posted September 24, 2003 And what if I double my cork panels with plywood ? Quote Link to comment Share on other sites More sharing options...
edster00 Posted September 24, 2003 Share Posted September 24, 2003 I believe that false corners need to be very sturdy, heavy, and solid to re-direct the bass sound waves as a true wall/corner would do. I think of cork as light weight and a 'porous' material, more suited to absorb sound than reflect it. Before I finished my basement listening room I used ¾" plywood panels nailed to the back of the bass bins for false corners. At louder volumes my panels would come loose from the pounding of the bass. When I finally built substantial false corners I couldn't believe how much tighter the bass became and how much bass I had been missing. It can't hurt anything to try your cork panels, I am sure they would be much better with ¾" plywood on the side against the speakers, but they need to be tightly against the speakers with a good seal maintained between the tailboard and the corner.

ricktate Posted September 24, 2003 Share Posted September 24, 2003 I think we need a pic to see what your idea is,,,,i would use your idea till i made a proper false corner with a base on it ,,,instead of making a 2x4 wall....just take seveal 2x4 and lay them down on wide face and screw into 4 foot square 3/4 inch plywood base, build it up like logs ,,crossing over at the corner ,,every other one will be different length...screw into each other and to 3/4 inch base ...you will end up with a very soilid corner.Then finish it with drywall,paneling,etc. Then seal speaker to the base and corner ,you will be surprised im sure of the results....with this set up you can then point the K-Horns into the room any way you want,,,you only need the false corner as high as the bass bin part of speaker.....just make one and try it next to what your using now to see if it improves.....i think it will be a lot better....and easier to make than you think....rick..p.s. let us know what you decide Quote Link to comment Share on other sites More sharing options...
WMcD Posted September 24, 2003 Share Posted September 24, 2003 A friend, in private, has pointed out I'm quite wrong about the "Organ" being the 9th. Rather, it is the 3rd. I hope no one ran out and tried to buy a recording. Gil Quote Link to comment Share on other sites More sharing options...
WMcD Posted September 24, 2003 Share Posted September 24, 2003 Here is the Dope from Hope on false corners. I'd think the cork idea will work well too. Gil Quote Link to comment Share on other sites More sharing options...
