VIABLUE QTC Spikes
The VIABLUE™ QTC Spikes are the definitive solution for audiophiles seeking to eliminate resonance and maximize sonic clarity. Designed to prevent disturbing vibrations from transferring to furniture or floors, they provide a vivid, clean, and detailed sound profile. With a massive 200 kg load capacity per set, QTC Spikes are engineered to support and isolate even the heaviest floor-standing speakers, tube amplifiers, and high-end turntables with absolute stability.
KEY FEATURES
- Massive Load Capacity: Supports up to 200 kg per 4-piece set, ideal for heavyweight reference gear.
- Integrated Height Adjustment: Innovative mechanism allows for 2 mm fine-tuning directly at the spike body.
- Vibration Elimination: Bundles and discharges resonance through premium stainless steel peaks.
- Surface Protection: Includes extra-large Ø 25 mm QTC Discs with stainless steel inlays.
- German Precision: Two coated metal bodies connected with a massive 20 mm fine thread for smooth alignment.
- Versatile Mounting: Includes adapters for M6 threads and compatible with optional M8 or threaded inserts.
PRECISION HEIGHT ADJUSTMENT
Unlike standard spikes that rely on loose thread sticks for leveling, the QTC Spikes feature a smart, integrated adjustment system. The two coated metal bodies are connected by a massive 20 mm fine thread, allowing you to adjust the height by up to 2 mm simply by rotating the spike itself. VIABLUE says the large thread diameter guarantees maximum stability.

MAXIMUM PRESSURE FOR ACOUSTIC PURITY
The engineering philosophy behind the QTC Spikes is to pool the body weight of your speaker or device onto one small point of contact. This creates maximum pressure on the underlying surface, which VIABLUE says eliminates all disturbances. Vibrations are bundled and discharged through the exchangeable premium stainless steel peaks, and VIABLUE says the result is a vivid, clean and detailed sound.

COMPLETE MOUNTING FLEXIBILITY
VIABLUE™ ensures the QTC Spikes fit a wide variety of systems right out of the box. Each set includes premium stainless steel "diameter decreasers," allowing the spikes to fit standard M6 threads securely. For equipment without threads or different sizes, the spikes can be adapted using optional thread sticks or inserts. The set also comes with four extra-large Ø 25 mm QTC Discs with premium stainless steel inlays, to protect underlying surfaces like wooden floors.
