Srinath Posted May 20, 2020 Share Posted May 20, 2020 My pictures are failing upload - not sure why. But my question is about wood vs plywood vs MDF. I know Khorn has 54 pieces of wood per speaker. I know the top is made of edge glued wood. I know the visible painted parts of my bass bin are plywood. I'm wondering what is wood vs plywood vs MDF on an 86 and if its changed from then to the new ones. I saw a clip of the designer say mdf when talking about new Khorns recently.

JBryan Posted May 20, 2020 Share Posted May 20, 2020 I have a pr of '87 Khorns I've worked through the bins and tops a few times and I never came upon any MDF - only plywood. Quote Link to comment Share on other sites More sharing options...
Srinath Posted May 20, 2020 Author Share Posted May 20, 2020 Nice, good you saved me that trouble, and the top hat seems to have edge glued wood on top for sure and likely also the bottom ? Quote Link to comment Share on other sites More sharing options...

Sorry, Wrong on both accounts. The finely-veneered panels on YOURS are ACTUALLY poplar-lumber-core-plywood, finely-veneered on one side, and birch veneered on the other...which was also delivered with fine-veneer edge-banding already attached where edges are visible from the front of the speakers when properly installed into room corners.so are the top-hat side panels and the bass bin front panel. The bottom panel of the bass bin will be approximately 1/2" thick Baltic Birch plywood, because it was assembled separately as a bass bin "wing assembly", originally! IIRC, Your K-horns will also ONLY have three SOLID wood pieces in each bass bin! One will be the "splitter" which is mounted to the inside of the front panel of the bass bin, opposite from the compression slot of the woofer motor-board...the other two will be reinforcing blocks for POSITIVE-LONG-TERM-construction assembly for the upper and lower "wing assemblies" which make up portions of the two rearward-bends of the bifurcated Bass horn lens....you can see all of these three solid wood pieces if you open the woofer access door...and look upwards , then downwards to find the pair of reinforcement blocks...then remove the woofer and look thru the compression slot of its motor-board and you will see the "splitter" in front of it...mounted to the bass bin front panel's back side. . Trust me, they will al be there, as mentioned, I outta know! I fabricated all of them during that time era method of K-horn production! Other than those three items, everything else "wooden" in your K-horns is either poplar-lumber-core plywood, Baltic birch plywood, OR cabinet-grade custom-ordered 3/4 inch birch plywood. Anything else is one of two types oi glue, or a mixture of the metal stuff: screws, finishing-nails, staples, and T-nuts. EDIT: Sorry, I forgot!....I left out two more solid wood pine or fir pieces of 2/4 lumber per K-horn...they are at each end of the top-hat H/F motor-board...just look into the rear of the top-hat and you can see them...one on your left, the other to your right...with grill cloth wrapped around them and then stapled to them. 2 Quote Link to comment Share on other sites More sharing options...
Srinath Posted May 25, 2020 Author Share Posted May 25, 2020 Oh cool, thanks from someone who may have built mine - Very nice. Let me read and google and learn etc - but you're saying the top pentagon shaped piece is Poplar lumber core plywood ? Not edge glued wood ? Cos I seem to have distinct grain which changed in a sharp line and when viewer from the back edge where its painted black the wood grain also changes as though it has a glue line - but I should also say - its the tightest cleanest most undetectable glue line I have ever seen. So maybe its not. Quote Link to comment Share on other sites More sharing options...
Srinath Posted May 25, 2020 Author Share Posted May 25, 2020 Oh I saw that on some of the 70's Khorns the top hat doesn't come off. Do the side panels come off on those ? What year did the top become removable. And new Khorns are MDF ? when or if - did that change ? Quote Link to comment Share on other sites More sharing options...
Srinath Posted June 3, 2020 Author Share Posted June 3, 2020 Also I see some where the tweeter is to the side of the mid horn. Mine has it on top. Did they change it or were they both running concurrently depending on the sub model ? Quote Link to comment Share on other sites More sharing options...
JohnA Posted June 3, 2020 Share Posted June 3, 2020 Side tweeters are modifications or Speakerlab SKs. 1 Quote Link to comment Share on other sites More sharing options...

Not speaker labs (which are IMHO fantastic as well I have those 901 copies, solid stuff). But these are the genuine Klipsch ones. No side tweeters either - they are on top and have the square magnets - making them the M series and all 100% Klipsch. Quote Link to comment Share on other sites More sharing options...

Srinath Posted June 5, 2020 Author Share Posted June 5, 2020 Yea mine got a little beat up in a move - which is what happens when you hire gorillas to move stuff I guess. Some scratches but I would still play them every hour of the day no problems. Quote Link to comment Share on other sites More sharing options...

You are looking at two or more different cabinet builds, and thinking they are all the same...There was D-style, C-style, and yours which are B-style! All different specific buids and each priced differently....with B-style the most expensive of them all! B-style has a trap panel pon thope of the bass bin...then another one atop that but with a collar between the two...then the very top trap panel. C-style has one trap on the top pof the bass bin...NO CLLLAR AT ALL, and another trap above that one with sides connecting the two traps...one above the other...only the bottom trap is NOT removeable...the rest is! D-style is no trtaps at all...the bass bin front panel actually extends upwards to become the motor-board for the H/Fsection...no removeable wood above the bass bin body , itself! I'm leaving the rest of your questions for JRH to answer...over an hour of typing your answers already and that is enough FOR ME...good night! . 1 Quote Link to comment Share on other sites More sharing options...
