Huiez Posted March 12, 2017 Share Posted March 12, 2017 What is the best way to reinforce Chorus II cabinet? Can anyone point me to some specific directions and materials? I notice just a bit of a buzz in one of mine at certain mid-bass frequencies. Also do the speaker gaskets need to be renewed or replaced? Thanks in advance for some direction.

absolve2525 Posted March 13, 2017 Share Posted March 13, 2017 Are you sure its the cabinet? It's a pretty heavy and well made box. Sounds like there's an air leak, possibly through the gasket material. Check the rear passives also, and that screws are tight. I had to redo the gaskets on my Tangents. You can buy gasket tape from Parts Express website. Quote Link to comment Share on other sites More sharing options...
jason str Posted March 13, 2017 Share Posted March 13, 2017 Pull the passives out and make sure the cones were not overextended. Quote Link to comment Share on other sites More sharing options...
moray james Posted March 13, 2017 Share Posted March 13, 2017 see pictures of post #31 on the page below. This cabinet is a Quartet but is very similar layout to Chorus 11 you can brace the same way, notice how the stringers are used to tie all the braced sides together. Cross brace below and above of the woofer and mid horn and important to cross brace below and above the passive. moray james. http://audiokarma.org/forums/index.php?threads/starting-to-mod-klf-20-cabinet-crossover.372783/page-2 Quote Link to comment Share on other sites More sharing options...

Maybe some plastic wood to fix where it pulled out of the MDF? Quote Link to comment Share on other sites More sharing options...

Is this type of mod going to offer much at mid to low volumes or is this going to help out just at ear bleed levels? I would guess a more rigid cabinet would help overall?

Lightly push on the inside of the outermost part of the cone and make sure it is still attached to the frame, if it is loose it will need to be re-glued. Use a flashlight if needed.

jason str Posted March 13, 2017 Share Posted March 13, 2017 About the stripped screw hole simply break a few toothpicks and wood glue them back into the stripped screw hole & re-install the screw. 1 Quote Link to comment Share on other sites More sharing options...

Well that makes sense! Thank you. I will double check that passive as well, I am pretty sure it is intact. Quote Link to comment Share on other sites More sharing options...

We have some woodworkers who post here, so listen to them, not me, but I've always heard putting a mixture of wood glue and sawdust in the hole was a good solution. Edit: I just saw where Jason weighed in and gave you a solution ^^^ using toothpicks. He's the woodworker, listen to him. 1 Quote Link to comment Share on other sites More sharing options...

I am showing my ignorance going to start to evident from mid to higher levels. What you will find is that when you clean things up and you lower distortion you are going to find yourself listening at higher and higher peak levels simply because it is much more realistic. The interesting thing is you probably won't realize that it's happening. Quote Link to comment Share on other sites More sharing options...
