DMSD Audio Tools speaker decouplers

High-end speaker decouplers from Italy. Set your desktop/bookshelf speakers on these to isolate them from a desk (or other surface) for a cleaner, tighter sound. This is a set of 8 decouplers (4 for each speaker). The maker of these offers two different models: the model I'm selling is the DMSD 50, which is for speakers that are 26.5 pounds or lighter. (The other model, the DMSD 60, is for larger speakers.) Bought them a year ago (May, 2018). Used them for less than a month, because I ended up returning the KEF desktop speakers I had bought (too bright for my taste) and replacing them with some Raidho floor-standing speakers. The decouplers have been sitting idle in their original box ever since. I chose these particular decouplers because of a favorable review from a mixing engineer. You can watch his review here: https://www.youtube.com/watch?v=Pm2d8uHtpHc They certainly improved the sound of the KEFs - increased clarity, tighter bass, less reverberation.

The DMSD Decoupling System has been developed with both the Studio and HiFi user in mind to provide an effective, professional grade speaker decoupling solution. Designed and manufactured in Naples, Italy by Dave Mastrodonato Studio Design, DMSD Decouplers are crafted using the highest quality aerospace grade materials, which have been carefully selected based upon Dave Mastrodonato’s prior two decades of industry experience. His ultimate aim, to create the most effective and versatile speaker decoupling solution on the market. DMSD Decouplers unique construction significantly reduces sound energy transmission from speaker cabinet to supporting surfaces during audio playback. This has the effect of dramatically improving perceived low frequency precision and tightening the stereo image, therefore providing an aural representation truer to the speaker manufacturer's intended design.
