STEG Q4C – High-Precision Concentric Speaker for Exceptional Clarity

Concerto Art of Sound

The STEG Q4C is a premium concentric speaker designed to deliver unmatched accuracy, natural tonality, and superior soundstage performance in compact applications. Engineered with STEG’s Italian acoustic technology, the Q4C provides crystal-clear detail and exceptional stability, making it ideal for high-end car audio systems that demand precision.

Perfectly Balanced Sound in a Compact Design

Thanks to its concentric driver architecture, the Q4C ensures that all frequencies originate from the same point source. This creates:

  • Improved imaging

  • Accurate sound positioning

  • Smooth phase alignment

  • More realistic vocal and instrument reproduction

Despite its compact size, it delivers powerful detail across the full spectrum — from crisp highs to articulate mids.


High Efficiency with Excellent Power Handling

With 95dB sensitivity (2.83V/1m), the STEG Q4C offers impressive efficiency, allowing it to produce high output even with low power.
Its 30W rated power makes it perfect for OEM upgrades or high-fidelity systems requiring precision without distortion.
