Sound Addicted Subble 1.8" Isolation Feet for 6–8" Speakers

Sound Addicted Subble 1.8" isolation feet are adhesive silicone bumpers that reduce vibrations and decouple 6–8" speakers and small subwoofers for clearer, tighter sound.

These hemisphere-style silicone feet from Sound Addicted are engineered to sit discreetly under studio monitors, desktop speakers, and compact subwoofers to limit cabinet-to-surface vibration. With an elevated durometer rating and supplied 3M adhesive, the Subble feet deliver a stable, non-slip platform that’s easy to attach and remove, letting you optimize speaker placement without drilling, spikes, or bulky isolation pads.

How do these isolation feet affect bass and midrange clarity?

By decoupling the speaker cabinet from the desk or shelf, the Subble feet reduce sympathetic vibrations that smear low and mid frequencies. The result is tighter bass presence and better-defined mids, especially with nearfield monitors placed on work surfaces.

• Minimizes cabinet resonance transfer to furniture
• Improves transient response for punchier bass
• Reduces unwanted coloration from reflective surfaces

Will the 1.8" size fit my 6"–8" monitors and small subwoofers?

The 1.8" hemispheres are intended to tuck beneath 6"–8" speakers without visually dominating the footprint. They support monitors up to approximately 45 lb per set of four, so they’re suitable for most bookshelf nearfield monitors and compact powered subs.

• Compact footprint hides under most speaker grills and bases
• Recommended for 6"–8" drivers and similarly sized enclosures
• Each set of four supports up to about 45 lb total

How easy is installation, and will the feet damage equipment?

Installation is straightforward: peel the backing and press the supplied 3M adhesive pads to the silicone feet, then stick them to the speaker base. The adhesive is designed for a strong bond but removes cleanly in most cases, leaving little to no residue when peeled correctly.

• Includes pre-cut 3M adhesive for quick mounting
• Peel-and-stick method avoids drilling and hardware
• Removes cleanly if heated slightly and peeled gently

How durable are the bumpers and what material properties matter?

Subble feet are molded from silicone with a higher durometer (shore ~35) to strike a balance between stiffness and damping. That firmness helps control resonance without compressing excessively under typical monitor weight, preserving isolation performance over time.

• Silicone construction resists compression set and aging
• Higher shore hardness improves vibration control
• Hemispherical profile concentrates contact area for stability

Who this is for: Sound engineers, podcasters, desktop musicians, and audiophiles who use six- to eight-inch studio monitors, powered bookshelf speakers, or compact subwoofers will benefit most from these isolation feet. If you need a low-profile, non-invasive way to reduce cabinet vibration, tighten bass response, and prevent skidding on desks or racks, the Subble 1.8" silicone bumpers provide a small, professional-grade solution that installs in minutes and stays out of sight.
