Loudspeaker & Rack Decoupling/Isolation

Giant Cone/Spike Decoupling Glider

Herbie's Audio Lab is proud to introduce a completely new, revamped and upgraded lineup of audio loudspeaker and rack isolation feet. This new lineup of footers represents great value; only the finest materials are used, and all are manufactured and/or assembled in-house. By experimenting outside the conventional "box," we have solved several of the frustrating problems associated with traditional loudspeaker isolation, achieving new benchmarks for loudspeaker footer performance and versatility.


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

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/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 speaker cabinet-friendly medium-tack adhesive applied to one side or both. Sticky Fat Dots bond the speaker/stand interface more strongly than Blu-Tac and are removable without damage to speakers, stands, or the Sticky Fat Dots.

Sticky Big Fat Dot and Sticky Square Fat Dot are the same as 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 Mobility

Floor-standing loudspeakers sometimes need mobility for room aesthetics, acoustic experimentation, social and other reasons. Conventional casters are terrible for audio applications however, 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 anyway, 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.

Having glider mobility makes it easier to fine-tune and maintain ideal loudspeaker positioning. Positioning, like toeing the speakers in or out just a little, moving them closer to a corner or away from a wall, has dramatic acoustical effect. Bass response, linearity and soundstage imaging are among the acoustic phenomenon addressed by speaker positioning. With any change or upgrade of components or accessories, some readjustment of loudspeaker positioning is often beneficial to bring everything up to the next 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.

Giant Cone/Spike Decoupling Glider: Same attributes as regular Cone/Spike Decoupling Gliders described above, with more dBNeutralizer "beef" and broader base. With embedded brass, stainless steel, or titanium disk, Giant Cone/Spike Decoupling Gliders are ideal for extra-heavy duty, for severe vibrational environment, or use with speakers and component racks on deep, spongy carpet. Appropriate for use on any kind of bare or carpeted floor. 2-3/8" wide by .67" tall (conical indentation is .144" deep). With convex off-white polymer bottom.

Name: Bob
Message: I have a cabinet with a plywood shelf that will sit on the horizontal legs of 10 L-shaped shelf supports. The horizontal leg of each support is 1/2" wide x 5/8" long. (The shelf will carry over 100 lbs of equipment, so I'm installing more than the usual 4 supports per shelf and reinforcing the shelf with aluminum stiffeners.)

Although I already have quite a bit of isolation and vibration control installed system-wide (including some Herbie's products), I'd like to further isolate the shelf from the cabinet by placing either a 3/4" diameter Small Fat Dot or a 5/8" diameter Extra Thick Grungebuster Dot under the shelf on each support.

Which product would be more effective for isolating the shelf from mechanical vibrations entering through the cabinet?

Webmaster's reply: A 1/2" regular grungebuster Dot between each shelf support and shelf should be sufficient and provide a superb decoupling interface. (If you have severe footfall or other macro-type vibration issues, Extra-Thick grungebuster Dots would be appropriate for a turntable shelf.)

Message: I have a SOTA Moonbeam turntable...and while happy with the table, have sat upon making certain improvements to it. First was replacing the thin and flat platter with a Music Hall Acri-Plat. It not only looked better...it sounded better. Then I replaced the hard plastic feet with Herbies Threaded Stud Gliders. These also made a visual improvement as well as a sound improvement. Audio is now more focused and far less smeared!

Message: Hello, I have some of your Herbie's "fat dots" and love them. Recently my daughter moved into an upstairs unit and she asked me to help her with isolating her Pioneer HPM100 loudspeakers from the downstairs neighbors. Thought that I would ask your opinion on this and maybe you could refer me to one of your products.

thanks,
Thom Middlestadt

Webmaster's reply: If on bare floor or stand, four Big Fat Dots or Giant Fat Dots under each speaker. If on carpet, four Giant Fat Gliders under each speaker (Gliders are appropriate on bare floor, also). If on stand, a dBNeutralizer isolation product between stand and floor is additionally beneficial as well.
Name: please recommend
Message: I have Mirage OM-12 floorstanders sitting on laminate wood flooring. Could you suggest which product will help improve the sound?

Webmaster's reply: Cone/Spike Decoupling Gliders placed under the stock spikes is a popular choice with these and similar speakers.
Name: Mike
Message: I bought new speaker stands. They are big and filled with 3 bags of sand each weighing about 150lbs each. Tried moving one before placing the speaker and it ripped a spike out.

I now want to just remove the spikes all together. Would the big fat glider be a viable option?

Webmaster's reply: Sure.
Name: tom chi
Message: I have 380 pound evolution acoustics speakers. Can your product handle this weight.

Webmaster's reply: Yes. For 380-pound speakers which generate a lot of mechanical acoustic energies, you'll want a beefy product for the isolation/decoupling interface. For Evolution Acoustics, a Giant Cone/Spike Decoupling Glider under each of the stock spikes, or four Giant Fat Gliders directly under each speaker cabinet would be ideal.
Name: Tom
Message: I have a pair of Aperion Verus Grand Towers on ceramic floors (basement level) (60+ lbs each). They are on the bases that they came with. The floors aren't perfectly even, so they shift ever so slightly when handling them. What product would you recommend?

Webmaster's reply: Threaded Stud Gliders in place of the stock spikes.
Name: Chris
Message: Hi, I need some feet for my rack, which is about 120lbs and holds about 130lbs of gear. I have suspended hardwood floors. Would threaded stud gliders be up to the task of supporting my rack, or should I be looking at cone/spike decoupling gliders or even Giant decoupling gliders?

Thanks!

Webmaster's reply: Threaded Stud Gliders are more than capable, sufficient, and up to the task. Either of the options mentioned would do very well.
Name: Chris
Message: Greetings! I own a pair of Paradigm Phantom V2 floorstanders that are placed on an interlocking laminate floor (which was installed over hardwood). In your opinion, would the threaded stud gliders be a good match, or should I look at spikes + decoupling gliders? Thanks for your time! Cheers!

Webmaster's reply: Threaded Stud Gliders are ideal for this kind of application. Using a Cone/Spike Decoupling Glider under each of the stock speaker spikes would do virtually as well. With dBNeutralizer isolation though, there's really no need for spikes at all; when used with Gliders, spikes function primarily as just an extension of the speaker cabinet. If spikes are needed for leveling or tilt, Threaded Stud Gliders will readily accommodate those tasks, as well as provide the isolation to bring out the best sonic potential of the speakers and allow easy mobility when needed.

Message: I just purchased Tekton Lore speakers they weigh 55lbs. I live in a old house with hardwood floors. I can feel base notes through the floors what product do you suggest

Webmaster's reply: A Cone/Spike Decoupling Glider under each of the stock spikes. Or, four Giant Fat Gliders under each cabinet in place of spikes altogether.
