Superior Decoupling Spikes

shown with

1/4"-20 x 3/4" stud

Constrained-layered carbon fiber between mounting stud and spike achieves superior rigid decoupling between loudspeaker and floor. Precision-machined stainless steel spike pierces carpet and underpad for exceptional lateral stability. Threaded Superior Spike is adjustable for leveling and can be locked in place with optional-use jam nut (included). Ideal for tall, narrow speakers on spongy carpet, outriggers, and other applications where a rigid isolation and decoupling is desired.

Recommended for loudspeakers, subwoofers, platforms, racks, stands, or other load up to 100 pounds (45 kg) total.

"The Superiors absolutely trounced the stock spikes that came with my Von Schweikert loudspeakers. In an instant my high end was smoother, detail increased, bass was better defined, and the soundstage clarity increased. The entire presentation was noticeably faster."-John Zurek, Positive Feedback Online

"I am very happy with the carpet spikes, they work very well under my Martin Logans, better than their proprietary spikes. And they work very well too under the power outlets (conditioner). Smooth trebles yet a lot of details. Well defined bass and very good scene. The system sounds less 'digital.'" -Stefano Amico, Livorno, Italy

"The spike/grounding base combination: great surprise. Once installed, the bass tightened up appreciably and deepened, it was good before. Detail increased from the midrange on down. Really astonishing. Katherine came home from work and the first words were, "Alright, what did you do? This is huge."-Frank Englander, Colorado Springs, Colorado

"Steve, the decoupling spikes arrived the other day and have been placed under my sub-woofer. I had been having some boom from the subwoofer but I didn't know if it was system; the coordination of the sub and other speakers; or the way the sub sat on my carpeted floor. Well, I have found a large difference adding the decoupling spikes. I think the way you have integrated the damping material into the spikes is the answer as not only is the sub suspended a little above the floor but the damping seems to clear up the boom; the sound is now much more refined and clean. Thanks for the suggestions." -Ken McGuire, Calgary, Canada"

"I have a Spectron Class-d amp, with a granite slab on carpet under the amp. I just purchased and received your Superior Decoupling Spikes and very much like the improvement."-Will Gibbons, Arizona

"The last thing to be isolated was my subwoofer. After all the successive improvements I had heard so far, I knew that I would hear some kind of improvement. But I was not prepared for what I heard. There are not enough WOW's for this one! OMG, I was hearing deep bass like I didn't know existed.-Brent Tuthill, Hendersonville, North Carolina

"I have now installed your Threaded Superior Spikes and used them about 4 days. I installed the spikes on my Silverline Sonata MK III 110 pound speakers, capable of 25hz and noticed an immediate change. The sound became more transparent, the bass was deeper, more articulate and firmer, the treble was smoother, and the upper mid range that is grainy on large orchestral pieces lost some of the etch, violins had a nice sheen. These are the best speaker cones I have used through the years of pursuing this hobby and also the most reasonable.

"Good job, Herbie."-Marty Thomas, Modesto, California
