AudioControl A1 Altitude Series 1" Component Tweeters, 50W RMS, 4 Ohms (Pair)

The AudioControl A1 Altitude Series 1" Component Tweeters are a standalone pair designed for precision high-frequency detail in premium automotive systems, pairing a silk-dome diaphragm with a compact, durable polymer housing for easy installation and seamless integration.

• Power (RMS): 50 Watts — provides clean, continuous power handling for clear highs without clipping when paired with a suitable amplifier.
• Impedance: 4 Ohms — a standard car-audio load that works well with a wide range of amplifiers for efficient power delivery.
• DC Resistance (Re): 3.2 ohms — affects how the tweeter interacts with the amplifier and crossover network, influencing system design.
• Voice Coil: 0.8 in (20 mm) — a larger coil supports better heat management and stable high-frequency performance under load.
• System Frequency Response: 1,500 Hz to 20,000 Hz — covers upper midrange to treble, delivering detailed highs when paired with compatible drivers.
• Sensitivity: 86.5 dB 1W/1M; 89.5 dB @ 2.83 V/1M — indicates the expected SPL at a given input, helping size the amp for your build.
• Tweeter dimensions (overall footprint): Overall Diameter (with housing) 1.67 in / 42.5 mm; Cut Out Diameter 1.37 in / 35 mm; Mounting Depth 0.39 in / 10 mm; Overall Depth (with housing) 0.73 in / 18.5 mm — compact form factor suited to tight dash or door installations.
• Crossover Dimensions: Length 3.6 in / 92 mm; Width 1.3 in / 34 mm; Height 0.94 in / 24 mm — provides the physical footprint for the accompanying network in a component setup.
• In the Box: (2) A1 1" Tweeters, Manual — two tweeters accompanied by installation guidance for straightforward setup.
• Designed and Engineered in USA — built to exacting standards with American engineering principles.
• Silk Dome Diaphragm: Smooth, accurate sound reproduction with minimal distortion.
• High-Strength Polymer Housing: Durable construction with enhanced mechanical properties for vehicle environments.
• Wide-Bandwidth Response: Enables seamless system integration with other components.
• Compact Design: Small footprint ideal for vehicles with limited mounting space or challenging installation locations.
• Simplified Installation: Quick-release housing, direct wiring, and universal sizing for hassle-free installs.
• Prop 65: To our California customers: Please view your Prop 65 warning here.

In a premium component system, the A1 tweeters deliver precise highs with minimal distortion, while the compact form factor and quick-install features reduce install time in dashboards, doors, or kick panels. The 4 Ω load and 50 W RMS handling ensure compatibility with a broad range of amplifiers, enabling clear, extended high-frequency detail that complements midrange and bass components for a balanced soundstage.
