With its 62 cm height, this stand positions bookshelf speakers exactly where the tweeters should be: at ear level when seated. The S05 follows a proven structure at Triangle, the Picardy-based manufacturer located in Soissons since 1980: a central aluminum tube combined with a molded glass base and a non-slip top plate capable of supporting loads of up to 25 kg.
The central tube of the S05 is made of aluminum, a choice that combines mechanical rigidity and vibration damping. This column can be filled with fine sand or metal beads (sold separately under the reference “Stand Filler”) to increase the stand’s inertia and reduce the transmission of resonances generated by the movement of the drivers.
The bottom plate is a molded glass panel made at high temperature. The molding process gives the glass greater density and strength than ordinary glass.
Triangle supplies two sets of accessories to adapt the S05 to different floor coverings. The height-adjustable steel spikes are suitable for soft floors such as carpets or thick rugs: they pierce through the covering to anchor the stand directly to the hard surface underneath. The rubber feet are intended for hard floors (tiles, parquet, polished concrete) where spikes could scratch or slip. Protective discs are also included to safeguard delicate surfaces.
The total height varies slightly depending on the option chosen: 62 cm with rubber feet, 64 cm with metal spikes.
The plate that supports the speaker measures 18 cm wide and 29.5 cm deep. These dimensions accommodate most bookshelf speakers on the market, including compact models such as the Triangle Comète or Capella, as well as larger speakers from other manufacturers. The non-slip coating prevents any movement, even during dynamic passages at high volume.
A cable passage is integrated at the back of the tube. Speaker cables can thus run down inside the column and exit at the base, clearing the visual field and simplifying system organization.
Triangle offers a specific mounting kit for Comète 40th speakers. This system allows you to screw the speaker directly to the top plate of the S05. The whole assembly then becomes a single unit, with decoupling taking place only at the base of the stand. This option will appeal to those who want to maximize mechanical rigidity between the speaker and its stand, or who are concerned about accidental tipping (children, pets).
The dimensions of the plate (18 × 29.5 cm) and the maximum load of 25 kg allow the installation of most bookshelf speakers on the market. The non-slip coating holds the speaker in place without any fixing. Only the screw mounting kit is reserved for the Comète 40th.
Fine sand fills gaps more completely and adds extra damping thanks to friction between the grains. Metal beads (Triangle Stand Filler) provide higher mass for the same volume and present no risk of moisture. Both options work; the choice mainly depends on what you have available or your preference.
On thick carpet or rugs, the spikes pierce through the soft covering and stabilize the stand on the hard floor. On tiles, parquet, or concrete, the rubber feet prevent scratching and provide sufficient grip. If in doubt, try both configurations and keep the one that feels most stable.
The rear opening can easily pass a pair of standard speaker cables. For large-gauge cables or multiple pairs, check the available space before installation.
A pair of S05 stands can support the surround speakers for the side or rear channels. The 62–64 cm height places the tweeters slightly above a seated listener’s ear, which corresponds to common recommendations for surround channels. For the main front speakers, check that this height suits your setup.
No. The S05 works without filling, with a unit weight of 4.5 kg. Filling improves stability and reduces vibrations transmitted to the floor, but the effect varies depending on the speaker, the floor, and listening levels. Many users start without filling and adjust later.

Beautiful appearance, classy and high-quality, be careful with the thickness of the pre-mounted speaker cable, it's not always easy to feed it through the speaker stand

Must-have for your Triangle bookshelf.
Beautifully finished. The glass base plate looks very chic.
It comes with custom-made plastic bags you can fill with sand. This is recommended, as the stands themselves are not very heavy.
