Little Superior Carpet Spike: Loudspeaker/Subwoofer Decoupling
With nickel-plated brass spike coupled to a wide stainless steel disc and decoupling layer of Herbie's dBNeutralizer, Little Superior Carpet Spike neutralizes vibration, decouples, and holds loudspeaker cabinet motionless for superior performance. Ideal for use on all carpeted floors; anchors well to concrete, wood, virtually any floor material.
...
Utilizing a wide base for lateral stability, Herbie's Little Superior Carpet Spikes need no stud or adhesive (though optional pressure-sensitive adhesive or stud is available); just place three or four under each loudspeaker. Easy to install: just tilt your cabinet a little, place a Little Superior Carpet Spike under it, then set the cabinet down. dBNeutralizer gets a good grip, preventing the cabinet from moving or sliding.
...
With 3/4" nickel-plated brass cone, this footer gives a neat, low profile; loudspeakers look like they are sitting directly on the carpet, and in many cases are, though all the cabinet weight is resting solidly on the Little Superior Carpet Spikes. Recommended for loudspeakers, subwoofers, amplifier platforms, or other load weighing up to 65 pounds (30kg).

"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 carpet 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 carpet 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 Carpet 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 Carpet 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.
...
"However let me note that these spikes should be installed properly. Some users might find the same problems that I encountered with these and other speaker footers. The spikes sink firmly into my heavy carpet and appear to be stable but the sound does not improve because they do not contact the floor. So I got out my carpet piercing Exacto knife and put 2 small X slits where the cone point touches the carpet, I them rocked the big speaker until I felt them contacting the floor. I have many slits in my carpet from speaker mounting but once the speaker is moved the slit disappears. The next problem was the speakers' threaded inserts protrude about a sixteenth of an inch from the bottom of the speaker surface so the flat portion of the spike does not not contact the bottom of the speaker. This produces an overly bright treble. I made some wood washers a little larger in diameter than the top of the spike and a little thicker than the insert protrusion. Perfect."

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