Q Acoustics Concept 300 Tensegrity Speaker Stands (Pair)

The Concept 300 Tensegrity Speaker Stands sit at the top of Q Acoustics' stand range as a purpose-built support system for the flagship Concept 300 standmount speakers. Rather than a conventional column or pillar design, these stands apply the structural principle of tensegrity — a term coined by Buckminster Fuller in 1960 describing structures where rigid elements in compression are held in place by a continuous network of elements in tension.

Tensegrity Construction

Each stand forms a tripod from precision-machined solid stainless steel rods (the compression elements) connected by thin stainless steel cables (the tension elements). This creates an inherently stable, self-supporting structure with an extremely low surface area. Q Acoustics' research found that conventional speaker stands vibrate three times as much above 300Hz compared to this tripod geometry. With minimal contact area between stand and speaker, re-radiated sound is reduced to virtually nil.

Isolation Base Suspension System

Integrated into the top plate is Q Acoustics' Isolation Base Suspension System, which uses four springs to decouple the Concept 300 speaker from the stand structure. This suspension prevents vibration energy from passing in either direction — floor-borne vibrations cannot reach the speaker cabinet, and cabinet energy is not transmitted down through the stand to excite the floor. The system is tuned specifically for the mass of the Concept 300 speaker (14.5kg each).

In the Box

Each pair includes two stands, six spikes with rubber spike covers for hard floor protection, six top plate screws, eight speaker mounting screws, and an owner's manual.
