jjptkd Posted January 17, 2022 Share Posted January 17, 2022 The extra 15lbs of weight is really the only unknown parts alone would not account for this much so has to be in the cabinet-- must have thicker panel(s) (maybe higher density?) and or added internal bracing. 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted January 17, 2022 Share Posted January 17, 2022 Would be nice to know of motorboard thickness 5000 versus 500. Quote Link to comment Share on other sites More sharing options...
OO1 Posted January 17, 2022 Share Posted January 17, 2022 the T-5000 is 14 lbs heavier /MDF Quote Link to comment Share on other sites More sharing options...

Sensitivity on Klipsch speakers is based almost exclusively on the woofer performance and horn drivers are dialed down to match. thanks. i will open them up & see what the insides look like, but 15lbs difference in woofers is a huge amount, could the k28s be a PRO woofer like the k48 vs a standard k24? just cant see the woofer or a few pieces of small wood for bracing being 15lbs heavier. anyone open up a pair of 5000s to see what the internal cabinets look like for bracing or different thicknesses??

The magnet on the k-76 is much smaller than the k-75 same diaphragm though 1 Quote Link to comment Share on other sites More sharing options...
jjptkd Posted January 17, 2022 Share Posted January 17, 2022 The k-79 in the Chorus line has the same size magnet as the k-75 but the Chief pointed out recently that there is a difference in the gap size to increase the sensitivity in the k-79 so all three tweeter magnets are different but the diaphragms and horns are the same. 3 1 Quote Link to comment Share on other sites More sharing options...
001 Posted January 17, 2022 Author Share Posted January 17, 2022 thanks for the info on these guys, answers my questions. now i just need to give them a listen to see how i like them compared to my forte2 & chorus2. also just pulled a tweeter real quick & the motor board is 3/4" thick but does look to be less dense than MDF but not quite as cheap as the particle board you buy for home projects at home depot etc. must be the majority of the weight difference, strange the brochures dont mention cabinet wood or MDF anywhere. 1 Quote Link to comment Share on other sites More sharing options...
geoff. Posted January 17, 2022 Share Posted January 17, 2022 That’s the 5000s in the picture. The lame attempt at bracing was an afterthought, I had them open to PL (adhesive) all of the joints. In another thread years ago I mentioned you could literally shine a flashlight inside the cabinets and see light through some of the joints on the outside. It “seamed” to be a common issue in similar threads. Might be a good idea to invest in a tube. The K-601 horn was an afterthought too. It actually fits flush in the cabinet and you could notch it around the tweeter or woofer, if you were so inclined, for the fun of it. Of note, I have had three pairs of K-601 horns over the years, and each pair had a different composition ranging from thin brittle plastic (pictured, probably first year) to thick non-resonating resin. ...starting to regret selling them, NOT, waaaay too many projects on the go, as usual. 1 Quote Link to comment Share on other sites More sharing options...

jjptkd Posted January 17, 2022 Share Posted January 17, 2022 Looks like some type of particle board not MDF I don't remember any bracing at all in my old 500's but it's been well over 10 years since I had those. I thought the panels were less than 3/4" on the 500's something like 5/8's IIRC but again it was a long time ago. I paid $250 for mine at the time and felt they were a great deal at that price very decent speaker for the money. 2 Quote Link to comment Share on other sites More sharing options...

Do a google image search of "particle board" there's numerous grades with various sized wood chunks what is seen in these pictures is a very common type / density.

These were a bare bones budget speaker offered at discount prices it seems hard for me to believe that they would reengineer the cabinets between these two models while keeping the same exact dimensions and cut-outs. My guess is that the listed weight is probably wrong in one of the two speakers from what I can see. 1 Quote Link to comment Share on other sites More sharing options...

MDF = Medium density fiberboard. Larger fibers = low density LDF HDF is smaller fibers & heavier I believe. (been a while) Very similar products. 1 Quote Link to comment Share on other sites More sharing options...
