merkinman Posted November 6, 2020 Share Posted November 6, 2020 I'm thinking about drilling in some threaded inserts for spikes on my CWIVs. With other speakers I've had decoupling the speakers really helped clean up the bass and improve the imaging. Anyone try this? I think the base is particle board...a little worried about it splitting. 2 Quote Link to comment Share on other sites More sharing options...

KROCK Posted November 6, 2020 Share Posted November 6, 2020 I have my Corns on 4" Maple platforms, which have spikes under them. 👍 2 Quote Link to comment Share on other sites More sharing options...

JohnJ Posted November 6, 2020 Share Posted November 6, 2020 `Mornin, Something about a hollow space below speakers I have never felt comfortable with except small factory risers. After having Heresy for almost three decades, I tried something prior to getting new speakers. This actually did what you talk about improving the bass for them, it was immediately noticeable. Recognized their name from the Pyle-Driver speakers I had in an old car that were great. https://www.amazon.com/gp/product/B00SVRLR06/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 They don't stand out because they are dark, there is no movement between the item and anything else due to gravity. 1 Quote Link to comment Share on other sites More sharing options...
KROCK Posted November 6, 2020 Share Posted November 6, 2020 @JohnJ That's an isolation platform, I think the O P want's to decouple not absorb the base from his CW. 2 Quote Link to comment Share on other sites More sharing options...

Hey @KROCK Cool. I mentioned it because they did what the title said he was looking for. It literally refreshed the 25 plus year old Heresy that I had then. The bass was more articulate and deeper to me and they had been in that location for four years at the time! 1 Quote Link to comment Share on other sites More sharing options...
MicroMara Posted November 7, 2020 Share Posted November 7, 2020 You ´ve followed the placement recommondation ? Which speaker have you used before ? 1 Quote Link to comment Share on other sites More sharing options...
KROCK Posted November 7, 2020 Share Posted November 7, 2020 @JohnJ ,we all know or get to know every system is different. What works for me , might not work for you. There's a lot of factors to consider. Do you agree? 1 Quote Link to comment Share on other sites More sharing options...
Peter P. Posted November 7, 2020 Share Posted November 7, 2020 I installed spikes on my kg sw subwoofer. The factory feet were missing so holes were already present. I bought my spikes from Meniscus Audio and was referred to them by Klipsch, when I e-mailed asking if I could get replacement feet for my subwoofer. I followed the directions for drilling the proper pilot hole size, then threaded in the female inserts using an allen wrench, I believe. I'd recommend you buy a plain board, cut it to size, and install the spikes on it, rather than the speakers themselves. Mount the speakers on the spiked board and test to see if they make the difference you're looking for. If you're satisfied, THEN install the spikes on the Cornwalls. 1 Quote Link to comment Share on other sites More sharing options...

B&W, Tekton, GoldenEar, Tannoy, Harbeth. Decoupling with spikes made a pretty big difference in most cases. Quote Link to comment Share on other sites More sharing options...

The OP's Cornwall IVs are leaps and bounds ahead of those Heresy IIs I was talking about and they were on hardwood with a lot less deep digging into bass territory! Environment is a big factor for all audio endeavors! 1 Quote Link to comment Share on other sites More sharing options...
merkinman Posted November 15, 2020 Author Share Posted November 15, 2020 I was able to install threaded inserts to the base without any issues. Ironically I prefer the sound without spikes. At least now I know. 1 Quote Link to comment Share on other sites More sharing options...
