trav0810 Posted November 18, 2018 Share Posted November 18, 2018 I currently have a pair of Cornsacalas. They seem to be just a bit "boomy". Most of the other speakers I have owned have used some kind of dampening materials in them. Are there any recommendations for using any packing or Black Hole type resonance cancellation material?

moray james Posted November 18, 2018 Share Posted November 18, 2018 I would suggest that the boom is a placement issue not a problem with the loudspeaker they are a time honored reflex design and are perhaps the favorite among Klipsch speakers for bass quality especially impact the only other Klipsch which has such great impact is the KG5.5. The reflex vent is what damps the driver/cabinet system resonance. Leave the box alone and play with the placement that should get you where you want to be. 1 Quote Link to comment Share on other sites More sharing options...

Shakeydeal Posted November 19, 2018 Share Posted November 19, 2018 I agree that placement can make a huge difference. But one of the things that bothered me about Bob's cornscala was that on some material the sound was a little "boxy" sounding. One certain bass notes you could actually hear the contribution from the cabinet from the rear panel flexing. I added some dynamat to the rear panel and that helped quite a bit. This might help in your situation too. Shakey Quote Link to comment Share on other sites More sharing options...

jason str Posted November 28, 2018 Share Posted November 28, 2018 A simple motorboard to rear panel brace would not be a bad idea. Quote Link to comment Share on other sites More sharing options...
parlophone1 Posted November 29, 2018 Share Posted November 29, 2018 +1 Internal bracing is the way I would go. Quote Link to comment Share on other sites More sharing options...
