Description
Spikes are used because point support can improve perceived focus and speed by reducing unwanted contact area. The problem is practical: many users avoid placing spikes directly onto floors or shelves due to the risk of damage. Traditional spike cups solve the damage issue—but often at a sonic cost, because the cup material can introduce a recognizable “tone” or coloration.
The QSB-3810 is Acoustic Revive’s answer: a spike receiver made from solid natural quartz, designed to act as a protective interface while still improving sound quality rather than dulling it. Acoustic Revive states that natural quartz resonates far outside the audible band, so it does not generate its own “material sound,” allowing the system to remain natural, lively, and texturally rich while upgrading perceived quality.
Why natural quartz for a spike base plate?
Quartz is selected here for its unique mechanical behavior and high hardness. Acoustic Revive positions quartz as a material that avoids the typical sonic “signature” of spike receivers, helping preserve the original character of your speakers or equipment while tightening focus and improving clarity. In systems where you hear “ringing,” “thickness,” or a tonal shift when using metal cups, quartz can be an attractive alternative because it is intended to be more neutral.
Designed for real-world setups: protect surfaces, keep point support
The QSB-3810 is not just a flat disc. It includes a spike pocket (receiver) to keep the spike positioned and stable: approximately 3mm deep and 18mm in diameter. That makes placement easier and reduces the risk of the spike slipping, while still maintaining point-contact behavior.
Where it works best
Use QSB-3810 under:
-
Loudspeakers with spikes (especially on delicate floors or racks)
-
Audio racks and stands with spiked feet
-
Power distributors and heavy components fitted with spikes (where applicable)
Because each piece is solid quartz, it can be a strong choice for high-resolution systems where even small resonance changes are audible.
Natural crystal characteristics and handling notes
Acoustic Revive notes that natural quartz can contain cracks or inclusions, describing these as evidence of natural origin. They also warn that while quartz is very hard, it can be weak against sharp, concentrated impacts—so avoid pressing spikes with excessive force and avoid dropping the pieces from height.
Limited edition availability
QSB-3810 is offered as a limited edition with a stated global limit of 700 pieces (not sets). It is sold as 3-piece and 4-piece sets.

The ultimate spike receiver that improves sound quality has arrived.
Audio equipment and speaker spikes are designed to provide point support by being inserted directly without spike receivers. However, many people are hesitant to do this because it can damage floors or rack shelves.
Using spike receivers to prevent scratches can degrade sound quality due to the inherent tonal characteristics and quirks of the receiver material.
The QSB-3810 spike receivers are crafted from rare natural quartz crystals. Because natural quartz has a resonant frequency far beyond the human audible range, it does not impart any inherent tonal characteristics to the material itself. This allows for a natural, vivid, and vibrant sound and texture, resulting in a significant improvement in quality.
Natural quartz crystals are formed over hundreds of years.
It is said that natural quartz takes 1 million years to grow just 1 mm.
The quartz crystal used to carve the QSB-3810, which measures 38 mm in diameter and 10 mm in height, must have been formed over an incredibly long period of time.
It is no exaggeration to say that receiving spikes with the QSB-3810 is equivalent to supporting audio equipment and speakers with the Earth itself.
*The QSB-3810 contains cracks and impurities, which are proof of its natural origin. We hope you can feel the pulse of the Earth.
*While natural quartz has very high hardness, it is extremely vulnerable to sharp, strong forces. Please be careful not to apply strong spikes when placing it on the ground, and do not drop it from a high place.
