Audio T Verdict
The IsoAcoustics GAIA-TITAN Series brings the company’s threaded directional isolation technology to exceptionally large floorstanding speakers and subwoofers weighing as much as 280kg.
Each set of four replaces compatible factory spikes or threaded feet, forming a strong connection with the cabinet while reducing mechanical energy travelling into the floor and limiting vibration reflected back towards the speaker.
Depending on the loudspeaker, room and supporting surface, this can help deliver tighter bass, greater clarity and a more open, stable and accurately focused soundstage.
Three models cover different weight ranges: Theis for cabinets up to 145kg, Rhea for cabinets up to 190kg and Cronos for cabinets up to 280kg.
Correct model selection, thread compatibility and orientation are essential. Each capacity applies to one complete set of four supporting one speaker or subwoofer, so a conventional stereo pair normally requires two sets.
IsoAcoustics GAIA-TITAN Speaker and Subwoofer Isolation Feet
The IsoAcoustics GAIA-TITAN Series consists of heavy-duty threaded isolation feet for large high-end floorstanding loudspeakers, subwoofers and compatible speaker systems.
GAIA-TITAN isolators replace the existing factory spikes or feet and screw into the cabinet’s threaded inserts using the supplied model-specific studs.
The high-quality stainless-steel construction contains IsoAcoustics’ patented directional isolators, designed to manage mechanical energy while resisting excessive lateral movement and oscillation.
Four Isolators Support One Speaker
Each GAIA-TITAN package contains four isolation feet for one speaker, subwoofer or compatible speaker assembly.
A conventional stereo pair normally requires two complete sets. The stated capacity is the total load supported by all four isolators, not the capacity of each individual foot.

Patented Isolation for Large Loudspeakers
A large floorstanding loudspeaker generates substantial mechanical energy as its drive units move forwards and backwards.
When the cabinet is connected rigidly to the floor through conventional spikes, some of that energy can travel into floorboards, furniture and the surrounding structure.
GAIA-TITAN provides a controlled mechanical connection that reduces this energy transfer while retaining the stable support required by a very large speaker.
Reducing Structure-Borne Vibration
Structure-borne vibration travels mechanically through floors and the building rather than through the air.
This can cause lightweight flooring, doors, cabinets and nearby equipment to resonate along with the loudspeaker or subwoofer.
Reducing the amount of mechanical energy entering the supporting surface can help the listener hear more of the speaker itself and less of the surrounding structure.
Reducing Reflections Back into the Cabinet
Mechanical energy can also reflect from a hard supporting surface and travel back towards the loudspeaker cabinet.
IsoAcoustics identifies these reflected vibrations as a potential contributor to bass smear, reduced clarity and a less precisely organised soundstage.
Managing this interaction can help bass notes sound more clearly separated and allow voices and instruments to occupy more stable positions within the stereo image.
What Improvements Might You Hear?
- Tighter and more controlled bass
- Improved low-frequency definition
- Clearer midrange reproduction
- Greater separation between instruments
- A more open soundstage
- More stable stereo imaging
- Reduced floor and furniture vibration
The scale of any improvement will depend on the loudspeaker, room, floor construction, positioning and original support arrangement.
Only the Lower Isolator Contacts the Floor
The GAIA design is arranged so that the external metal housing does not create a rigid path directly to the supporting surface.
Only the lower isolation element contacts the floor, allowing mechanical energy to be managed through the internal isolator rather than bypassing it through the outer housing.
This controlled path is central to the intended isolation performance.
Directional Isolation
GAIA-TITAN isolators are directional and should be aligned with the motive forces of the loudspeaker.
The internal design manages energy along the front-to-back axis of the speaker while resisting unnecessary sideways movement and oscillation.
Correct orientation is therefore an essential part of installation.
Align the Logos Towards the Listening Position
Install each GAIA-TITAN with the IsoAcoustics logo facing forwards towards the listening position.
The isolators may alternatively be rotated through 180 degrees with the logos facing directly backwards. Do not install them with the logos facing sideways beneath a conventional front-facing speaker.
Speakers with Side-Firing Bass Drivers
IsoAcoustics recommends retaining the normal front-facing orientation even when the loudspeaker includes a side-firing bass driver.
The logos should remain aligned towards the listening position rather than being turned towards the side-mounted woofer.
This keeps the isolators aligned with the overall motive forces of the complete loudspeaker system.
Threaded Connection to the Cabinet
GAIA-TITAN feet connect to the threaded inserts used by the speaker’s original spikes or feet.
The selected threaded stud is fitted to the isolator and then screwed securely into the speaker base.
This strong connection ensures that the cabinet’s mechanical energy is managed through the internal isolation system.
Confirm the Thread Size Before Installation
Do not force a threaded stud into the loudspeaker or subwoofer.
An incorrect diameter or pitch can damage the cabinet’s threaded insert. Check the speaker manufacturer’s information, compare the original spike or use the Product Selection Wizard below.
GAIA-TITAN Theis Threads
Theis is supplied with M8-1.25, M14-2.0 and ½”-13 threaded studs.
These sizes cover many large loudspeakers and subwoofers within its weight range, although compatibility must be checked for the specific cabinet.
GAIA-TITAN Rhea Threads
Rhea is also supplied with M8-1.25, M14-2.0 and ½”-13 threaded studs.
The difference between Theis and Rhea is their physical size and supported weight rather than their standard supplied thread selection.
GAIA-TITAN Cronos Threads
Cronos is supplied with M10-1.5, M14-2.0 and ½”-13 threaded studs.
The M10 option replaces the M8 size supplied with Theis and Rhea, reflecting the thread arrangements commonly found on some of the heaviest loudspeakers.
Alternative Thread Sizes
IsoAcoustics offers additional thread sizes through its distributors for speakers that do not match the three studs supplied with the selected model.
The correct alternative should be ordered rather than modifying, forcing or substituting an unsuitable thread.
Audio T can help identify the required thread size where the speaker model is known.
Speakers Without Threaded Inserts
GAIA-TITAN requires suitable threaded inserts beneath the speaker, subwoofer or compatible stand.
Adding threaded inserts to a cabinet is not normally recommended because drilling or modifying the base may cause permanent damage and invalidate the speaker warranty.
Where suitable factory threads are unavailable, a different isolation solution may be required.
Selecting the Correct Weight Range
The correct model is selected using the total net weight of one speaker or subwoofer.
The weight limits are based on the performance curve of the isolators rather than simply the structural strength of the metal housing.
Isolation performance remains strong up to the specified limit but declines quickly if the set is overloaded.
Move Up a Size Near the Limit
IsoAcoustics recommends choosing the next larger model when the speaker is within approximately 10% of the stated maximum capacity.
Do not deliberately exceed a GAIA-TITAN weight limit.
GAIA-TITAN Theis Weight Range
A set of four Theis isolators supports one compatible speaker or subwoofer weighing up to 145kg.
Where the cabinet is close to this maximum, the larger Rhea model may provide a more suitable performance margin.
GAIA-TITAN Rhea Weight Range
A set of four Rhea isolators supports one compatible speaker or subwoofer weighing up to 190kg.
Speakers approaching the 190kg limit should be considered for Cronos rather than loading Rhea beyond its intended operating range.
GAIA-TITAN Cronos Weight Range
A set of four Cronos isolators supports one compatible speaker or subwoofer weighing up to 280kg.
This makes Cronos suitable for exceptionally large high-end loudspeaker systems where the standard GAIA range does not provide sufficient capacity.
Installation on Hard Floors
GAIA-TITAN can be installed on suitable wood, laminate, tile, stone and concrete floors.
The supporting surface must be stable, level and capable of carrying the complete loudspeaker safely.
Isolation can remain beneficial on concrete because mechanical energy can reflect from the hard surface and travel efficiently through the building structure.
Strong Contact with Smooth Floors
The lower isolator can grip firmly once the full loudspeaker weight has been applied.
This helps resist unwanted movement during playback but means that a loaded speaker should not be dragged across the floor.
The cabinet should be lifted or carefully raised before any attempt is made to reposition it.
Do Not Drag a Loaded GAIA-TITAN
Dragging a very heavy speaker can damage the isolators, floor or loudspeaker.
Use suitable lifting equipment, furniture sliders or the optional IsoAcoustics F1 Speaker Jack when access is required beneath the cabinet.
Installation on Carpet
GAIA-TITAN can be used directly on thinner carpet where the isolators remain stable and properly supported.
For thicker carpet or substantial underlay, optional model-specific GAIA-TITAN Carpet Disks create a firmer connection through the carpet to the floor beneath.
The correct disk must be selected for Theis, Rhea or Cronos.
Optional GAIA-TITAN Carpet Disks
GAIA-TITAN Carpet Disks are made from solid stainless steel and are supplied in sets of four.
Theis disks measure approximately 69 × 22mm, Rhea disks approximately 79 × 22mm and Cronos disks approximately 99 × 22mm.
They are optional accessories and are not included with the isolation feet.
Remove Carpet Disks Before Moving the Speaker
Do not drag the loudspeaker while the carpet spikes are engaged with the floor.
Raise one side carefully, remove the disks, then repeat on the other side before repositioning the speaker.
Suitable for Compatible Subwoofers
GAIA-TITAN can be used beneath a compatible subwoofer with suitable threaded foot inserts.
The selected model must cover the subwoofer’s complete net weight and use the correct thread size.
Reducing structure-borne vibration can help improve bass definition and reduce unwanted floor resonance.
Suitable Beneath Secured Speaker Stands
GAIA-TITAN can be fitted beneath a speaker stand where the loudspeaker is mechanically secured to that stand and the two operate as one structure.
The supported load must include both the loudspeaker and stand.
The stand must also provide suitable threaded inserts for the selected studs.

Safety and Stability
The loudspeaker or subwoofer must remain upright, level and stable after installation.
Do not use GAIA-TITAN if the threaded studs cannot engage securely, the cabinet rocks or the installation creates a risk of toppling.
Power and signal cables should also have sufficient freedom so that they do not pull against or destabilise the speaker.
Do Not Modify the Loudspeaker Cabinet
Drilling or adding threaded inserts can permanently damage a speaker and may invalidate its warranty.
Use the Product Selection Wizard below or contact Audio T if the cabinet does not have a compatible factory thread.
