This lineup represents unprecedented value; only the finest materials are used and all products are manufactured and/or assembled in-house. By experimenting outside the traditional, conventional "box," we have solved several of the frustrating problems associated with loudspeaker coupling, decoupling and isolation, achieving new benchmarks for home audio loudspeaker performance.


Fat Dots: made with Herbie's dBNeutralizer(tm)

Big Fat Dots, 1-5/16" diameter

Reviews

This firm yet loosely crosslinked material is formulated specifically for blocking mechanical soundwave energies. Wide footprint gets a good grip and provides excellent lateral stability. Each Big Fat Dot supports and isolates from five to more than 200 pounds (90kg).

Big Fat Dot is 1-5/16" (33.3mm) diameter by 1/4" (6.4mm) thick. Perfect for floor-standing speakers, monitors, loudspeaker and stand decoupling, module decoupling, subwoofers, electrostatics, amplifier platforms, equipment racks.

Big, Small, Square, and X-Large Fat Dots are the same thickness and can be mixed and matched, or stacked, for unique applications. Use only as an interface between broad, flat surfaces (for use between spike and flat surface, use Herbie's Decoupling Glider or Cone/Spike Isolation Bases. For use on carpet, use Herbie's Fat Gliders.)

Fat Dots are not weight-specific. The major factor is the amount of vibration-blocking "beef" involved. Because of the wide variation of vibrational environments Fat Dots may be employed in, specific recommendations are not always possible. Various Fat Dot sizes have a lot of overlap in their capacities, so choosing between them in many cases in not critical. Standard Big Fat Dots, however, have proven to be particularly effective throughout a wide range of vibrational circumstances and loudspeaker types. Square Fat Dots are very popular as an isolation and decoupling interface between monitor speakers and stands (four under each speaker cabinet is recommended).

Small Fat Dot (3/4" dia.): $4.19 ea.
Square Fat Dot (1.06" x 1.06" square): $8.29 ea.
X-Large Fat Dot (1.5" dia.): $13.95 ea.
Giant Fat Dot (1.8" dia. x 9.5mm): $19.95 ea.

Adhesive: Monitor speakers often sit on small stand plates, causing a potential for a speaker being accidently bumped off the stand. Blue Tac is a common remedy. Though achieving some isolation benefit, this material induces some linear compromises, sonically falling significantly short compared to Fat Dots.

dBNeutralizer Fat Dots are available with a mild pressure-sensitive adhesive applied to one side or both. Though this unique adhesive makes only a moderately strong bond compared to conventional pressure-sensitive adhesives, Dots can be difficult to remove if adhered via both sides because getting adequate leverage can be difficult. When separated, the adhesive layer might remain on the stand or speaker instead of the Fat Dot, though the adhesive layer and Dot can usually be repositioned quite easily. Adhesive on one side only is recommended whenever appropriate.

Sticky Big Fat Dot and Sticky Square Fat Dot are the same as Fat Dots above (6.4mm thick), with the added adhesive not increasing overall thickness significantly. Sticky Small "Thin" Fat Dot is thinner (3.2mm thick).

Sticky Fat Dots:
Sticky Big Fat Dot (1-5/16" dia.): $12.95 ea.
Sticky Square Fat Dot (1.06" x 1.06" square): $10.59 ea.
Sticky Small "Thin" Fat Dot (15/16" dia.): $4.74 ea.

Von Schweikert Special: For module decoupling, eight Big Fat Dots plus two Square Fat Dots. Use four Big Fat Dots per speaker, one near each corner, with a Square Fat Dot in the middle.

Von Schweikert Special: $87.29


Ascendo C8 Special: Ten specially sized, extra-thick 35mm x 9.5mm Fat Dots, upgrade replacement for the ten rubber pucks used between a pair of Ascendo C8 speakers and stands. C8 Fat Dots can be used for other loudspeakers and other decoupling chores as well.

Ascendo C8 Special: $135.49

C8 Fat Dot (35mm x 9.5mm): $14.98 ea.


"Thin" Fat Dot

"Thin" Fat Dots

A thin layer of Herbie's dBNeutralizer material for decoupling and isolation in a moderate vibrational environment. Great as an interface between top of loudspeaker cabinet and weight. Polished granite slab, sandstone, paving block, ceramic tile, or other material placed on top of a loudspeaker cabinet or subwoofer can help to stabilize cabinet vibrations. Using "Thin" Fat Dots as an interface makes these materials even more effective and at the same time eliminates any sonic character the material might introduce.

Also great under vibration-control platforms and other general decoupling applications where a semi-firm interface is desired.

Same as Big Fat Dots above, but 1/2 the thickness (1/8").

"Thin" Fat Dot: 1-5/16" diameter.

(Small: 15/16" diameter.)


Floor-Standing Loudspeaker & Rack Isolation and Mobility

In addition to superb isolation, floor-standing loudspeakers need mobility for fine-tuning soundstage and imaging, to find the best interaction with room acoustics, and for aesthetic or social reasons. Conventional casters are terrible for audio applications, because various rollers and wheel housings introduce reverberations from floor and loudspeaker vibrations, adversely affecting the loudspeakers' performance.

Loudspeakers and equipment racks scarcely need to be rolled rolled around, not like a service cart at a hotel. They just need to be moved a little from time to time. Rather than rolling on wheels, an ability to slide across the floor is sufficient. Herbie's loudspeaker Gliders enable mobility on bare floors and carpeted floors while providing superb decoupling and sonic improvement. Besides general overall benefit throughout the sonic spectrum, deeply extending, linear bass with pronounced definition is the most consistently reported improvement achieved with Herbie's Gliders.

Positioning, like toeing the speakers in or out just a little, moving them closer to a corner or away from a wall, can have dramatic acoustical effect. Bass response, linearity and soundstage imaging are among the acoustic phenomenon addressed by speaker positioning. With any change in room decor or upgrade of components or accessories, some readjustment of loudspeaker positioning is often needed to maintain proper phase relations and keep everything synergized at an optimal level.

Special note about Gliders: when moving speakers on Gliders, always push cautiously from the bottom of the speaker cabinet or rack, not from the top.

Loudspeaker spikes are more effective when used in conjunction with Herbie's dBNeutralizer decoupling, especially with wood or suspended floors, whether carpeted or bare. Likewise, if your spikes couple firmly to your cabinet and are themselves solid and relatively free of coloration, they will complement Herbie's Decoupling Gliders very well by easing some of the workload and making the Gliders even more efficient. (Herbie's Cone/Spike Decoupling Gliders are used under your present spikes or cones.)

Features fiberglass-reinforced dBNeutralizer(tm) decoupling base and extra-thick brass, stainless steel or titanium disk. Fitted into Magic Sliders, they can be used on virtually any kind of floor, bare or carpeted, with easy-sliding mobility. Extra-deep conical indentation prevents spike from slipping out when lateral pressure is applied. Suitable for audio racks, stands and loudspeakers of virtually any weight. 1-3/8" diameter by 1/2" tall. With speaker load, height from bottom of Glider to bottom of conical indentation is about 5/16" (8mm).

Brass: superb hi-end results with most audio systems (our default recommendation).

Stainless steel: superb hi-end results with most audio systems.

Titanium: best-looking and best-sounding results possible.

Cone/Spike Decoupling Glider

brass: $16.89 ea.

Name: Vidar
Message: Hi. I have hardwood floor and DIY loudspeakers. (ATS4 troels gravesen). Bass cabinet weight is some 75kg. Mid treb cabinet is 18kg. What do you recommend?

Webmaster's reply: Four Giant Fat Gliders under each bottom cabinet (or Giant Cone/Spike Decoupling Gliders if using spikes). Four Big Fat Dots between each pair of speaker modules.
Name: Chris
Message: Hi. I need to decouple a table as much as possible from the bare wooden floor surface. On the table there are heavy speakers, a keyboard, a computer so the weight is a lot. What do you suggest?

Webmaster's reply:Assuming the table has wooden legs or non-pointed legs, a Giant Fat Dot under each leg, or for easier mobility of the table if needed, a Giant Fat Glider under each of the legs. Also consider four Big Fat Dots between each speaker bottom and table top.
Name: Gerry
Message: What would you suggest for Spendor A6 spikes on a hardwood floor?

Webmaster's reply: Either a Cone/Spike Decoupling Glider under each of the stock spikes, or Threaded Stud Gliders in place of the stock spikes altogether.
Name: Damijan
Message: Hi I have DIY speaker about 40kg each with spike on tile/concrete slab floor. Is there any benefit to decoupling them from the floor, and if so what would you suggest? Thx!

Webmaster's reply: A decoupling and isolation interface between speaker and floor is always sonically beneficial. For 40kg speakers, Cone/Spike Decoupling Gliders under the spikes is our most popular solution. Or, you could use Threaded Stud Gliders in place of the spikes. With either, you'll most likely achieve better bass definition with subtle sonic improvements throughout the audio spectrum, plus easier mobility of the speakers when needed.
Name: Mark Ambert
Message: Thanks so much for a GREAT product! i set up my speakers & the X-Large Fat Dots work like a charm. The benefits were immediate and easily recognizable. The top speaker is an SP Tech Timepiece 2.1 monitor which weighs a hefty 65lbs. I have them positioned on a stereo pair of ACI Titan Subs that i use as speaker stands (see pic). These subs put out some serious low end and needed to be isolated from the monitors - the Fat Dots more than did the trick and resulted in more clarity and a much better sound stage. I will be looking to buy more of your products to further isolate other components in my system. Vibration control is the key to improved dynamics and clarity in a high resolution system.
Name: Todd
Message: Hello, I have a pair of B&W 685S2 speakers sitting on the desk which causing vibrations, the room is too small there's no way that i can put them on speaker stands.

I'm wondering which product would allow isolating from the desk and the speakers?

Thanks,
Todd

Webmaster's reply: Either Medium or Large Soft Fat Dots should work very well for isolation between the desk and speakers.
Name: Ben
Message: Hi, I am using Focal 1027BE speakers where the base is an odd shape, please advise what type of footers will be best. Thanks.

Webmaster's reply: Regulard Cone/Spike Decoupling Gliders under each spike on the bottom of the loudspeaker would work very well for the Focal 1027BE. If used on very thick carpet, Giant Cone/Spike Decoupling Gliders would be more appropriate, especially if you plan on moving the speakers frequently.
Name: David
Message: What would you suggest using under Merlin VSM speakers? These have spikes and are designed to be firmly attached to the floor. I have hardwood floors.

Also, on the same surface what would be best for a component rack system with spikes?

Thanks so much, I love your products.

Webmaster's reply: For VSM speakers, a Cone/Spike Decoupling Glider under each of the stock spikes. For the component rack, a regular or Giant Cone/Spike Decoupling Glider under each spike.
Name: Rob
Message: Good morning STEVE:
which do you recommend to place under Vandersteen 2Cs on stands, on a padded carpet, Superior Decoupling Spikes or Giant Fat Glider.
Thanks!

Webmaster's reply: Giant Fat Gliders.
Name: Jordan
Message: Hello - I'm considering getting the Giant decoupling gliders to isolate my rack - I think it's a high vibration area because I have buses going outside my window...

If this is not the case will the isolation performance be reduced compared to the normal decoupling gliders?

thank you!

Webmaster's reply: I don't think there is any circumstance whereby Giant Gliders' isolation performance would be reduced compared to regular Gliders. Giant Gliders have much more vibration-absorbing and blocking "beef" for the job.
