AudioCircle Stuttgart Line 6.5" 2-way component speakers

The "Big Easy" of German Hi-Fi.

The AudioCircle Stuttgart Line (SL-C6.2) was engineered with a singular philosophy: "Simplicity meets Superior Sound." While many German-engineered speakers demand high-power amplifiers and complex installations to perform, the Stuttgart Line is designed to be the ultimate daily driver upgrade. It retains the precise, tonal accuracy AudioCircle is famous for but packages it in a high-efficiency design that wakes up your factory radio or entry-level aftermarket system.

The Tech

The secret to the Stuttgart Line's performance is its 3.2 Ohm Impedance. By lowering the resistance slightly below the standard 4 ohms, these speakers naturally extract more power from your source unit, giving you free volume and dynamic range without straining your electronics. The woofer utilizes a rigid Polypropylene (PP) Cone for snappy, weather-resistant midbass, while the 16mm Silk Dome Tweeter delivers smooth, non-fatiguing highs that reveal details lost by factory speakers.

The Experience

This is not a "clinical" or "sterile" studio monitor; it is a musical, enjoyable speaker designed for the real world. The sound is warm, punchy, and surprisingly detailed. Because they are designed with Inline Crossovers, installation is a breeze—no finding space for bulky crossover boxes inside your doors. Whether you are running them off a stock head unit or a small 4-channel amplifier, the Stuttgart Line delivers that premium "European Sound" signature—effortless, balanced, and refined.
